The regional conventionswill replace the NAB Fall Conferencesand the RAB Management Meetings.
Organizers plan to cover the entirespectrum of interest to broadcasters in-cluding government relations, sales,general management, engineering,legal, and FCC problems.
The Regional Radio Conventionswill be held on the following dates,which are the same as for the previouslyannounced NAB Fall Conferences: Oct.13-14, Atlanta/Fairmont; Oct. 16-17,Boston/Marriott; Nov. 10-11, New Or-leans/Monteleone; Nov. 13-14, Chica-go/Pick Congress; Nov. 17-18, Den-ver/Brown Palace; Nov. 20-21, SanFranc isco/Fairmont.

NAB Faults FCC OnAscertainment PoliciesThe National Association of Broad-casters has urged the Federal Commu-nications Commission to abandon itsproposed community guidelines infavor of a simple narrative statementreviewing steps taken to discern localproblems, plus a listing of those prob-lems and programs to meet them.
NAB said in comments filed with theFCC that the Commission's proposednew guidelines are arbitrary and in-flexible and, like the old primer they aredesigned to replace, "misfocus atten-tion upon ascertainment methodologyand only secondarily, at best, consider

MDS To Give Boost ToPay -TV In Many CitiesBy using the Multipoint DistributionService for some part of the haul to thesubscriber, pay -TV operators areabout to expand their services rapidlyin a number of cities, with plans formany other cities on the boards.
Cox Cable Communications andMicroband National Systems Inc, thelatter the operator of MDS in a numberof cities, announced at the end of Julythat Cox would use Microband's facil-ities to expand pay -TV in 12 majorcities, beginning with Atlanta. TheMDS, which is a "private" televisionbroadcasting service operating at 2150MHz, will carry the Cox programs toantennas on apartment houses andcondominiums not reached by Coxcable service. Programs will be dis-tributed to subscribers via each build-ing's MATV system.
A closely similar joint operationwith Microband has been announcedby Sammons Communications, cableoperator in Kansas City, to take pay-tvprograms to apartments, etc., in thatcity. And another will be set up inPhoenix, Arizona, where Microbandwill serve the American Cable Televi-sion Co. (see news item in BM/E,August).
In Chicago, which has no cable TVoperation, Video Entertainment Inc.will use Microband to, again, serveapartments, condominiums, hotels,etc., with pay -TV programs. TheMDS signal is converted to a mid -bandfrequency in each building, which

A spokesman forVideo Entertainment told BM/E that,even though the service was not slatedto start until sometime in September,they were getting a substantial numberof subscribers simply based on newsstories of its coming.
In every case the staple program-ming fare for the operations an-nounced is first -run movies, at leastinitially.
Looming ahead is national net-working of MDS-served pay TV. DonFranco, president of Microband, an-nounced an agreement, in principle,with Western Union for using theWestar Satellites to join Microband fa-cilities coast to coast. Implementationis expected within about 18 months. Invarious cities joint ventures have beenformed by several MDS applicants.

Satellite EarthStations Spread RapidlyA sampling of recent FCC announce-ments shows that applications for earthstations to help form various satellitecommunications channels are risingsharply in number. It is another in-dication that use of satellites will mush-room in the coming few years, bringingsomething of a revolution in manyareas of telecommunications.
An informal survey by BM/E ofearth station applications filed duringthe latter half of July showed that atleast 30 to 40 new earth stations weresought during that period. Many ofthese are for the satellite systems whichwill carry radio, telephone and televi-sion to many previously unreached sec-tions of Alaska. RCA promises launch-ings of new satellites this fall; WesternUnion, American Satellite Corp. andothers important in satellite expansionare all stepping up activity.
FCC ACTIONS
Cable ReconstructionDeadline CancelledAs reported in a BM/E bulletin inAugust, the Federal CommunicationsCommission has cancelled the March31, 1977 deadline for the reconstruc-tion of major market cable systems inexistence prior to March 31, 1972, tobring them into compliance with thechannel capacity and access require-ments of the rules (Docket 20363).
How the rule will ultimately be ap-plied to such systems depends, the FCCsays, on the outcome of a rule -makingproceeding begun June 3rd (Docket20508) addressed to that question.
Meanwhile, the FCC emphasizesthat the cancellation of that particulardeadline does not affect the followingrequirements which must still be met:major market stations must furnish byMarch 31, 1977 "composite" accessservices on available channel space,

AT KY -3-111,
THE BRAND OF REPORTINGAND THE BRAND OF FILM HAVE
A LOT IN COMMON.When the people in this
picture wave 3 fingers in the air,what they're saying is, "We'renumber one" at Springfield,Missouri, Channel 3. Thanks tohard-nosed reporting and hard-hitting promotion, KYTV is theundisputed broadcast king in theQueen City of the Ozarks. By amargin of 3 to 1.
In addition to top-notchjournalism, smart programminghas meant taking maximumadvantage of both videotape andfilm. And when the film camerasroll, the film they use is Eastmanfilm.
Over the past year, Channel3 news cameras unlocked thesecret of behavior modificationprograms in a Missouri federalprison; dug up a problem in theunderground water supply;whooped it up at a genuine hoe-down; and made friends with amountain hermit whose onlyother visitors dropped in by UFO.
Besides winning viewers,their documentaries have won a
silver gavel from the AmericanBar Association, a certificate ofachievement from the state med-ical association, and an Emmynomination.
For station manager DonMoeller, film is a logical choice:the equipment is rugged enoughfor any job, portable enough foreven the tightest spots, and the endproduct "looks absolutely greaton the air."
When the KYTV camerasaren't recording news, the KYTVpeople are busy making it,through locally produced sportsand entertainment shows. TakeVirgil Ward (front row left) andthe capable assistant you seeperched on his lap. You can catchtheir weekly fishing show on 87
markets in the U.S. and Canada.And when Virgil packs his rodand reel, he includes a reel ofEastman film.
Then there's Promotion Di-rector Clarence Martin (frontrow right). His 10 -second -filmID spots for the station not onlybuilt awareness, but they helpeddevelop a new market for locallyproduced commercials.
In the words of News DirectorBill Williams (2nd row, 4th fromright), "Film is essential to every-thing we do. After all, TV is thevisual medium, and it wouldn'tdo to have a person on cameramerely reading a piece of paper.We use film to tell our story. And,besides, our anchormen justaren't that pretty."

Rules for AntennaStrobe Lights are AdoptedIn a rule adopted July 8, 1975, the FCChas made high -intensity strobe lightspermissable for lighting of antennastructures, as an alternative to thestandard painting and red obstructionlighting (Docket 19931). The rule, theFCC says, does not obsolete acceptabil-ity of the painting and red lights, nordoes it make strobe lighting in anysense mandatory.
However, the FCC reserved the rightto specify, on new antennas, whichmethod would be required in accord-ance with FAA recommendations orwhen the standard marking proves to beconfusing, inadequate, or otherwisedangerous.
Broadcasters who want to start orshift to strobe lighting must get specificFCC authorization.
New FM TranslatorPolarization AllowedIn January, 1974, the FCC indicatedit would permit FM translator servicefor individual communities to be pro-vided by a combination of signals verti-cally and horizontally polarized. Theamendment allows the radiation of ver-tically and horizontally polarizedsignals either from a single antenna orfrom two antennas, each fed from aseparate radio frequency amplifier.
Cable Report FormRevised by FCCThe Commission has adopted a rulerevising form 326, the cable systemannual report form, with the aim ofmaking it both more complete as tofinancial data and less burdensome onthe cable operator (Docket 20247).
Among the changes: A new format closely resemblingnormal bookkeeping schedules A new schedule of all basic balancesheet accounts, replacing one that car-ried only original cost and depreciationdate Removal of the requirement thatcable systems report on a calendar yearbasis-they can now use their fiscalyear Elimination of the five -communitylimit on consolidated reporting in favorof a restriction to systems within a 40 -mile radius of the "lead" system
Cable operators whose, fiscal yearends after October 31, 1975, the effec-tive date of the rule, should make surethey have the new forms.
Institutional OwnershipLimit Increased by FCCThe FCC has proposed rule changesthat would set a 5% limit on in-stitutional ownership of broadcast andCATV companies. The proposal wouldamend the Commission's rules relatingto multiple ownership of AM, FM andTV broadcast stations and cross -ownership of CATV systems.
The rules now set a 1% limit forshareholdings in broadcast or cableoperations that have more than 50voting stockholders. However, mutualfunds have a 3% benchmark and banksa 5% benchmark for holdings on suchcorporations.
The proposed change comes after sixcompanies petitioned the FCC to makethe change.
Rules Revised forStation ApplicationsThe FCC has amended its rules to limitthe period for filing competing ap-plications for new FM and TV stationsand for filing petitions to deny, and theeffect of certain amendments to ap-plications for construction permits forAM, FM and TV broadcast facilities.
The rule changes provide a cut-offdate of 30 days after publication of theapplication which is similar to thosenow provided for AM new and majorchange applications. This date willavoid the disruption of applicationprocessing that occurs when a new,mutually exclusive application is re-ceived after processing of the originalapplication is nearly complete, the FCCsaid.
The FCC said its action was not in-tended to reduce the number of com-parative proceedings (although it rec-ognized this Might happen) but to"avoid serious (and occasionally re-peated) disruptions of the processingprocedure."

TEKTRONIXANNOUNCES
A newconcept in portable
instrumentationThe TEKTRONIX TM 515 Traveler Mainframe looks like fashionable flightluggage, compact and easy to carry, or slide under an aircraft seat.In reality, it's a five -compartment power module/mainframe that providespower and interface connections for TM 500 plug-in modular instrumen-tation. Plug in the new (two -wide) SC 502 15 -MHz dual -channel oscillo-scope, and you have the beginnirgs of a powerful take -along instrumen-tation system.
You can optimize a TM 500 system to your needs by selecting from morethan 30 plug-in modular instruments. With the TM 515 Traveler Main-frame and SC 502 Oscilloscope as a nucleus, select from DMM's, coun-ters, generators, power supplies, signal processors, and even blank plug -ins for your "home -built" circuits. Intended applications include areasfrom digital field service to medical, from audio/communicatons to on -site industrial controls maintenance.
The SC 502 is Tektronix quality, featuring clean triggering characteristics,delay line input, trigger view, trigger holdoff, 1 mV sensitivity, and thecapability of working through the rear interface circuit board with otherTM 500 instruments. It features a specially brilliant crt designed andbuilt by Tektronix for use in areas of high ambient light. Include a DD 501Digital Delay alongside the SC 502 and gain the capability of delay-by-events-you can then obtain stable digital displays from electromechani-cal sources like disc drives that would otherwise be too jittery for accur-ate viewing on any conventional oscilloscope. Include the DC 505A Uni-versal Counter and DM 502 Digital Multimeter to complete your TM 515package, and discover the benefits of simultaneous counter and DMMcapability with trigger level readout at the touch of a push button.
The TM 500 concept lets you take along on field servicing trips the sameinstruments you use in the lab or for production testing, thereby enablingyou to maintain the same standards on the "outside". The SC 502 Oscil-loscope, for example, may be used as a bench instrument in any multiple -compartment TM 500 mainframe, and it offers unique systems capabilities,as well, when operated in a rack in the RTM 506.

INTERPRETING THE&
REGULATIONS
AM Restrictions EasedBy Frederick W. Ford and Lee G. LovettPittman, Lovett, Ford and Hennessey, Washington, D.C.
In a move surprising for its swiftness, the Commissionrecently relaxed its AM acceptability and "suburban"policy restrictions, thus "opening the door" for existingAM stations to seek power increases and for new stationsto secure assignments.' Essentially, the new AM ruleseased past restrictions in four areas: 1 existing AMpower increases, frequency changes and fulltime ser-vices, 2 new stations proposing daytime or unlimitedtime operation, 3 creation of a new power classificationand 4 easing of "suburban" policy requirement.
The new AM rules eased considerably those institutedby the Commission in 19732 which were designed toconserve the remaining AM spectrum space for the as-signment of stations that would provide service to under-served areas and to encourage in areaslacking radio services. Pursuant to a rulemaking inquiryinitiated in 'November 1974, the Commission hereinfound the 1973 rules to be "unnecessarily restrictive incontrolling the rate of expansion of the standard broad-cast service, and that in some cases they failed to affordreasonable opportunities to satisfy developing needs fornew and additional aural service." The new AM rulesare designed to encourage community -oriented radioservices to many additional separate and distinctlocalities, especially newly -emerging suburban popula-tion centers. Comments on the four central areas ofCommission action follow.
Existing AM Station ChangesThe Commission loosened its power and time restric-
tions and opened its doors for applications for powerincreases and night-time services, so long as interferencestandards are maintained.
Existing daytime stations may seek power increases tothe maximum permitted on their channel so long as theymeet Commission interference standards3. That is, ineffectuating its power increase, the station may not causeor receive new interference; if the station presently re-ceives interference, it may continue to receive same solong as its total interference is not greater than that pre-sently received.
Existing daytimers may also apply for fulltime serviceon its present or another frequency upon a satisfactoryshowing that the community for which the station is'Report and Order in FCC Docket 20265 (lune 27, 1975).'Report and Order in FCC Docket 18651 (February 21, 1973).'FCC Rules and Regulations, Section 73.182(o).
proposed presently has fewer than two independent auraltransmission facilities during the portion of the day forwhich the new service is proposed. Put another way, inorder to secure fulltime service, the daytimer must showthat it will provide the first or add a second fulltimefacility to the community of license and, that no unusedFM station is allocated to said community. Note:AM -FM combinations, licensed to the same owner in thesame community, are considered as one. In addition, its"less -than -two -services standard" would not apply if anexisting daytimer proposed a new unlimited time stationif such would provide a first or second nighttime facilityfor the community. In the alternative, if the aforemen-tioned criteria do not apply, proposals which meet the"25% white (discussed in "New Facil-ities" section below) would be accepted.
An existing daytimer or fulltimer may also apply tochange its frequency to obtain a better allocation withoutbeing subject to the restrictions which apply to new sta-tions. Like applications for increases in power, ap-plications for changes in frequency need only meet thestandards covering overlap and daytime and nighttimeinterference. Regarding existing nighttime stations, theymay likewise seek power increases on their present fre-quencies and make changes in directional antennaesystems providing they do not cause interference to otherco -channel stations. The 50% rule on RSS applies hereand a Theoretical design may be utilized for the DA.
In addition, a nighttime station proposing to change itsfrequency must meet the same interference standards asdiscussed above. Note: The directional antenna designmust be a Standard design in accordance with the rules.
New Facilities
The AM rule changes will permit new nighttime ordaytime assignments to communities which meet the fol-lowing standards.
Assuming the availability of a frequency, the Com-mission will accept applications for new nighttime ordaytime AM assignments to communities with fewerthan two aural facilities licensed to said communityduring the relevant portion of the broadcast day. Ofcourse, the Commission still maintains its existing over-lap and nighttime interference standards.
If a community has two or more fulltime aural facil-ities, applications for new stations may still be tenderedproviding they meet the following exceptions. First, the

Introducing a Color Correctorfor Electronic News Gathering.
Electronic News Gathering makes tough demands upon the broad-caster. Color imbalance and colorimetry problems are frequently encoun-tered. Matching remote camera shots to indoor studio programs orassembling tapes from different locations or cameras is "chancy" at best.Often that fast -breaking story doesn't allow for camera rebalancing!
Thomson-CSF Laboratories now provides a solution to such difficultencoded signal color problems. With the Model 5500A Color Corrector,you'll be able to rebalance and match video signals after encoding. It canbe used either after the play -back tape machine or following the micro-wave receiver during live coverage. In most cases, a noticeablyimprovedcolor picture will result. For ease of operation, a Remote Control unit isincluded as standard equipment.
As an added feature, an optional automatic Sensor unit is also avail-able to control the Color Corrector for telecine use.
Whether for Electronic News Gathering, tape production or tele -cine use, the Thomson-CSF Laboratories Color Corrector System shouldbe working for you. Interested? Give us a call.

applicant must demonstrate that its facility would serve a25% "white area," i.e., that area lacking in inter-ference -free, full primary service from either an AM orFM station. Note: "Primary service," in its "whitearea" context, refers to a 1 mv/m AM or FM signal fromanother AM or FM station. As mentioned above, theserules obtain both to (1) new facilities and (2) daytimersseeking to go fulltime.
New Power ClassificationThe new AM rules also create a new 2.5 kW power
classification to provide an intermediate step between thepresent 1 kW and 5 kW classifications specified in therules. Power classifications permitted by "station class"are listed below.
Station Class:
IvIIIAIIIB
IAIIB oi D
Power Level
250, 500 watts or 1.0 kW1.0, 2.5 or 5,0 kW500 watts, 1.0, 2.5 of 5.0 kW10.0, 25.0 or 50.0 kW250, 500 watts, 1.0, 2.5, 5.0,10.0, 25.0 or 50.0 kW10.0, 25.0 or 50.0 kW
The Commission felt that the creation of a new stepbetween 1 kW and 5 kW "facilitated the maximum useof facilities" in cases where power greater than 1kW wasfeasible, but not as much as 5 kW.
Suburban PolicyThe new AM rules also relax the heretofore trouble-
some "suburban" The Com-mission's "suburban" policy, adopted in 1965, requiredapplicants for AM stations in suburban communities torebut the presumption that if the proposed station de-livered a 5 mv/m signal over a nearby larger community,the facility was intended to serve the larger community.In its new AM rules, the Commission will now foregoapplying their "presumption" to (1) uncontested ap-plications for new stations and (2) increases in power ofexisting stations. Hence, the rule will be limited tomutually exclusive applications that are involved in acomparative hearing. Note: The Commission issued itscaveat that applications for power "clearly in excess ofthat necessary to serve the proposed community of li-cense and its immediately surrounding areas" will beexamined carefully.
ConclusionIn relaxing its acceptability restrictions and "sub-
urban" policy for AM stations, the Commission hasopened the door for a flood of AM applications seekingnew or changed facilities. If a large backlog of un-processed applications develops, it said it would likelyimpose measures to control the rate of application filingsby declaring "open" and "closed" seasons for the filingof same. These measures will, if implemented, be tem-porary and advance notice will be given. The rulechanges are effective August 22, 1975. Applicants fornew or changed facilities should stay current with theCommission's processing schedule. BME

How To Backtime With Your PocketCalculator By Mary F Zoller
As an air -director for 39 TV's -Eyewitness News,- the author foundher attention focused on the second hand of a too -small clockhanging on a dark wall fifteen feet away. To determine whether thestation was running early or late she turned to the calculator as adigital backtimer. "It's the greatest aid since the stop watch,- she says.
If you ever have trouble backtiming or adding a columnof minutes and seconds, here's an efficient method youcan really count on.
Adding segment times, predeterming reel changes,backtiming, totaling commercial material in an hour, andfilling breaks can all be done quickly and accurately witha regular eight digit calculator. Any eight digit standardfour function calculator can add and subtract hours,minutes and seconds without changing the figures totheir decimal equivalents.
Because calculators function differently from model tomodel, you may have to set up the procedure a littledifferently i.e.: as to whether you punch + before thenumber you enter or = afterward. Regardless of thesequence, the events are the same, and the results fast.
Directors, both on -air and production, can utilize thecalculator with ease; as can traffic, accounting and sales.The method is simple, but like anything new, it takes alittle getting used to. To compute time, use the followingprocedure, watch how it compares to clock time as illus-trated in the left column.

Now insert this series as one entry. Your commercialbreak runs 1:05, so add 1, a 0 for the colon, and 05 as asingle entry.

3:30:02 Your total is 3029062
Here now is the key to the system. Because theseconds total over 60, add 940 to the total.

Whenever your seconds show up as 60 or more, add

940. You can keep adding 940under 60. For example:
until the seconds read
clock time calculator display4:00:00 Your program hour starts straight up at 4000000
20 Movie open runs 2034:15 Reel one of the movie is 34015
2:30 Break one at 4:10 runs 20302:50 Break two at 4:20 runs 2050
+ 2:40 Break three at 4:30 runs + 2040
4:42:35 The total is 4040155
The seconds are way over 60 so add 940 + 940
4041095
The seconds are still over 60 so add 940 again + 940
(4:42:35) This is the converted total OR timefor a reel change.
4042035
940 is the key. What you are doing with the additionof 940 is to carry the hundred digit over past 0 which youhave in place of a colon.
Use 940 to convert seconds to minutes.Use 940000 to convert only minutes to hours leaving
the seconds undisturbed.Use 940940 when converting both minutes and
seconds simultaneously, as in the example below.
4:42:35 To the previous total add 23:50 4042035+23:50 + 230505:06:25 To convert this total in both minutes 4065085
and seconds, add 940940 + 940940(5:06:25) The correct time stands at 5006025
The same principles apply to subraction. For example:
5:30:00 Local news ends at 5030000- 1:30 Last commercial break runs - 1030
5:28:30 Last Commercial break should start at 5028970To convert, subtract 940 - 940
(5:28:30) 5028030Sports segment runs 4:40 and includes
- 4:40 :45 for bull session. Subtract - 40405:23:50 Sports would start at 5023990
To convert, subtract 940 - 940
(5:23:50) 5023050
The only pitfall to avoid when learning to count timeon a calculator is to remember to use the 0 in place of acolon. Once you've mastered that small obstacle, you'vegot it. BM/E

Picking the Right ENG System forYour Market by Rupert Goodspeed
If you don't have $75-100,000 for a high quality ENG system, youdon't have to let the Revolution pass you by.
We take you now to Portland, Oregon.. .
Stand by Portland, five second roll. . .where our correspondant, Ross Hunter, has
the latest word on the fishing rights.. .
Okay, New York, sync lock. . .controversy between the U.S. Government
and the Umatilla Indians.Switch to PortlandGood evening, we're standing at Celilo Falls and
off to the north you can see.. .
Looks good Portland
It had better look good, Portland, because your effortsat the moment are being directly compared to those ofother network news gathering crews throughout thenation.
Network news groups, network owned -and -operatedstations, and key network affiliates in major marketshave an obligation to present a quality product to theviewer. It's not an easy obligation to fulfill, because youhave to be in the right place at the right time, with theright kind of equipment to cover a fast -breaking story.
Electronic news gathering techniques have beenpioneered by the networks and their owned -and -operatedstations. The networks have indicated to equipmentmanufacturers the kind of ENG gear they require and themanufacturers have responded. The problem for thesmaller broadcasters who want to be able to provide afeed on a hot story originating in their area is coming upwith the capital. And the move to ENG may be resistedby news crews who fear that it could trim their ranks, oreven eliminate jobs.*
Previous to the advent of electronic journalism every-one had about an even break: 16mm film was equallyaccepted everywhere. But now the station who can offerimmediate 'direct from the scene of action' through ENGviewing has gained the upper hand.
But it's not easy for the smaller or medium sizedmarket to find the $75,000 to $100,000 to set up a firstclass system. To match 16mm quality, a 3 Plumbicontube system plus a good video tape recorder is necessary.Is there a reasonable alternative? Of course there is, butyou trade off something for the lower dollar cost; namelyquality of finished product. And because of the reducedsensitivity of your lower cost equipment there are limita-tions on where, and under what conditions you canshoot.
Two -tube color camera systems have proven capableof doing an excellent job under a wide variety of con-

ditions, as long as there's adequate light. Some 1/4 -in and1/2 -in videotape recorders even include an assembly editmode, allowing a reporter to field edit an article or fea-ture. In the case of fast breaking news stories this tech-nique does not seem practical because you don't knowhow the story will end, and a taped story cannot be builtin any logical sequence. Therefore you'll still need avideotape editing capability and you'll have to use a$14,000 time base corrector in order to meet FCC specswhen you air your finished tape. All of which brings usto a total of $35,000 for a single camera electronic jour-nalism package of this performance level.
There are still other approaches to ENG for somesmaller market stations. Most stations already have aquad videotape machine, and by judicious scheduling thenews department can usually be allocated some time onit to put their shows together. Using a one- or two -tubecamera and a mating helical scan portable VTR, news-men can cover an event, bring all the tapes back to thestudio and then transfer them to quad through a time basecorrector; after which the product can be edited and as-sembled like a regular television show. The ENG in-vestment now comes down to approximately $25,000;(including the time base corrector) assuming of coursethat the station already has color editing capability inhouse on quad VTRs.
An even more economical approach to ENG is toobtain a one- or two -tube camera with a matchingVTR-either cassette or reel-to-reel-and invest in oneof the lower cost time base correctors. Here again there'san inevitable trade off for the cost reduction. Less ex-pensive TBC's use a different technique to accomplishtheir goal, resulting in a slight degrading of SNR anddefinition in the finished picture. The originating pack-age has come down to about $10,000, but you still facean editing problem. A 1/2 -in EIAJ color editing machinecan cost as little as $1,900 but that's really the hard wayto edit.
The most satisfactory solution appears to be investingthe required $13,000 in a decent editing system dedi-cated only to news and special events; to put your showtogether on this equipment and air it directly through atime base corrector.
It's been suggested that the most economical and prac-tical method, although not exactly electronic journalism,is the use of super 8mm film with the newly availablebroadcast super 8 color scanner (Kodak VideoplayerVP -1). Requiring only the investment in some super 8single system mag sound cameras, an editing system for
"However, except for the small two -tube hand-held cameras, ENG equip-ment weighs 50 lbs or more (not counting the VTR). Thus, two -man crewsare necessary whereas one man can handle a 16mm film camera.

super 8, and one of the super 8 scanners, this entiresystem can be put together for under $3,000; (exclusiveof the rapid processor). A lot of people knock super 8,but if you want to see a really surprising result, just feedthe output of one of the scanners through an inline verti-cal aperture corrector. Voila, a fine airworthy product ata nominal cost.
But if you don't already have an aperture corrector,that adds another $3,000, meaning that now you're up to$6,000 and you haven't started to buy or process filmyet.
Dilemma! If you send your film out to be processedyou've lost the immediacy of a hot report. If you put in arapid processor for super 8 you'll add another $12,500.That brings the total package to $18,500, and whoops,you're back up there to electronic journalism costs.
That's right, there's no such thing as a free lunch.Those who advocate staying with 'good old reliable
16mm film' conveniently forget that at one time they hadto lay out about $50,000 for editing and processingequipment. And keep in mind there's that $85,000 colorfilm island which has to be at least partially amortizedagainst your news operations.
It all seems to boil down to this: ENG, or electronicjournalism if you prefer, is a fact of life. To remaincompetitive you'll have to indulge in one form or anotherof the art. In view of that inescapable fact it seems ad-visable to make a careful examination of your com-petitive position in terms of the market you serve, thebudget you can justify for equipment, the savings youcould make by intelligent utilization of manpower andequipment, and the status and image you need to main-tain.
Weighing all these factors will enable you to de-termine the type of electronic journalism package bestsuited to your own needs. BM/E

How To Match Turntables To The
Format And The PocketbookRecently three classes of turntables have taken shape on thebroadcast market. Each can work well in the right seting.
Time was when there were two classes of turntables forbroadcasters-good and bad. In a sampling of usersundertaken for this article, BM/E found, as was to beexpected, that you can still get plenty of opinions forputting the available turntables into those old categories.The only trouble is that the engineers surveyed did notagree on which were which. With a sample of several

Turntable of all-out mechanical sophistication, and very highprice, is the EMT 930, imported by Gotham Audio of NewYork.
hundred it would probably work, but ours was necessar-ily much smaller.
What did have the weight of consensus and logic wasa currently emerging assignment of classes of turntablesrelated to classes of use. This division could not getstarted until a few years ago because before that one ofthe main classes did not exist. The movement is still inits early stages-but the outlines look firm.
What we might call the "standard" table, and refer-ring particularly to the brands that have survived on themarket over the years, is a rugged,long-lived, highlyreliable table, with a high -torque motor for quick starts.Price is usually in the $200 to $500 span. The secondclass is the new direct -drive turntable, which has won aspecial, if still very small, niche on the broadcast market:prices $300 to $600. The third is the thousand -dollar -plus super -performance machine, also with a definite butobviously limited market.
Taking the second class first: the direct -drive table hasa motor that turns at the turntable speed, and the tablefixed directly to the motor shaft. With such a slow -turn-ing motor "external" speed control becomes crucial andthis is usually accomplished with a servo system: thetable acts as a generator -tachometer, developing an errorsignal through comparison with some standard. Theerror signal can be fed into the motor drive to correct thespeed.
The slow -turning, low -torque drive means very lowvibration; the servo system means extremely low flutterand wow. The disadvantage is the comparatively slowstart.
The direct -drive table came along as pressure built upon certain classes of stations for ever better sound,making the table's particular qualities highly desirable.The FM or AM station for which the quality of sound isan important competitive element has had to upgrade thatquality steadily over the last few years. "Hi-fi con-sciousness" has spread through the audience, and homereceiving equipment used by such listeners keeps goingup in quality.
There is nothing presumptive about this trend; anumber of stations have felt it directly expressed in list-ener dissatisfactions, as described in previous articles inBM/E. It applies not only to "classical" music stations,but also to purveyors of MOR, or "beautiful music," orany other format if the station puts heavy emphasis onthe quality of the sound, and wins the allegiance of asubstantial number of listeners who are "turned on" tohigh-grade sound.
32 SEPTEMBER, 1975-BM/E
In Chicago, MOR station WYEN shifted to the direct -drive Panasonic SP -10's to reduce turntableflutter and rumble. Disc jockey Gary Meier cues up one at his right; another is to his left, in thebackground.
An example noted in the October, 1974 issue of BM/Eis veteran classical music station WQXR in New York.About three years ago the station had a sizeable listenerrevolt on its hands because of alleged high turntablerumble. Basic in this is the spread of medium-pricedhome playback equipment with extended bass response.The listener who hears a walloping 50 or 60 Hz from hisown records, without any audible interference from histurntable, will not stand for a subway -style noise alongwith his broadcast music. A broadcaster should haveprofessional equipment, presumably superior to thehome grade; it is a really serious blow to the "profes-sional" image if the broadcaster's record playing equip-ment is audibly inferior.
WQXR solved the problem with the Panasonic SP -I0,
one of the new breed of direct -drive turntables. A few ofthe others with similar experiences and the same solutionare WCLV, in Cleveland; WTMI, in Miami; WCRB, inBoston. In Chicago, MOR station WYEN went on theair with Panasonic SP -10's because the management putsits money on a very clean sound (among other elements)for survival in the fiercely competitive Chicago radiomarket (BM/E, May, 1972). The approach has workedout; WYEN is surviving quite healthily.
The extremely good speed stability-low wow andflutter-of the servo controlled tables becomes importantwhen the program includes a lot of slow piano, organ orviolin music, again intended for fairly sophisticated list-eners. (Note: jazz buffs are likely to be just as high on"hi fi" as classical listeners.)

CrEation of the new Calibration Standardd nEEd... thE accEptancE of
Stanton's 681 TRIPLE -E is unprEcEdEntEd!It was no accident!The Recording industry needed a new calibration
standard because it had been cutting discs with higheraccuracy to achieve greater definition and sound quality.
So, the engineers turned to Stanton for a cartridgeof excellence to serve as a primary calibration standardin recording system check-outs.
The result: the new calibration standard, The Stanton681 TRIPLE -E.
The rest is history!Major recording studios adopted it . . . as did many
of the smalier producers. Radio stations across the worldput the 681 TRIPLE -E on all of their turntables, both foron -the -air broadcasting and for disc -to -tape transfer.
And, audiophiles by their purchases have voted itthe oustanding stereo cartridge available.
The Stanton 681 TRIPLE -E offers improved tracking
at all frequencies. It achieves perfectly flat frequencyresponse beyond 20 kHz. Its ultra miniaturized stylusassembly has substantially less mass than previously,yet it possesses even greater durability than had beenpreviously thought possible to achieve.
Each 681 TRIPLE -E is guaranteed to meet its speci-fications within exacting limits and each one boasts themost meaningful warranty possible. An individually cali-brated test result as packed with each unit.
As Julian D. Hirsch of Hirsch -Houck Labs wrote inPopular Electronics Magazine in April, 1975: "When weused the cartridge to play the best records we hadthrough the best speaker systems at our disposal, theresults were spectacular".
Whether your usage involves recording, broadcasting,or home entertainment, your choice should be the choiceof the professionals . . . the STANTON 681 TRIPLE -E.

Your station's turntablecannot match the performance
or reliability of this one.
The Technics SP-10II.
Direct -Drive SystemEvery broadcast engineer wants to get rid of rumble,
wow and flutter. That's why manyradio stations, including the
country's largest dassical musicstation, WQXR-FM, use aTechnics direct -drive turnta-
ble. Now, Technics introducesthe SP -10 II. A new professional
direct -drive turntable, with something else everyengineer wants. Abundant torque.
Abundant TorqueAt 33 rpm, the SP -10 II will reach its exact playing speedwithin one-half revolution. This fast start-up speed isdue to Technics' manganese -aluminum permanentmagnet.
No Audible RumbleThe SP -10 II completely eliminates audible rumblebecause it's driven by a brushless DC motor that spinsat exactly 33 or 45 rpm. This slow speed introducesso little vibration into the system that any rumbleremains a silent -70 dB (DIN B).
No Audible Wow 81 FlutterThe SP -10 II has no belts, idlers or gears to producevariations in speed. The only moving part is the motor.And, since the platter is actually a part of the motor
(an extension of the rotor shaft), the SP -10 II has lessthan 0.03% wow and flutter (WRMS). What's more,it'll stay less than 0.03% regardless of AC line voltage,because the motor is electronically controlled by ananalog feedback system.
Direct -Drive ReliabilityThe SP -10 II is designed for the grueling work of abroadcast turntable. You can stop the platter with yourhand for hours without the danger of stretched beltsor damaged idlers. And the SP -10 II will maintain itshigh level of performance for years.
So if you'd like to improve the quality of yourstation's signal without spending a fortune, move upto the Technics SP -10 II.

MATCH TURNTABLES
.......................................
Sony has announced a new direct -drive table, the PS -8750,on sale in Japan for about $580, to come here soon.Crystal -controlled drive gives claimed speed accuracy of99.997%.
Current top -of -the -line Sony direct -drive table, PS2251,claims flutter of 0.04%, has price of about $430.00.
Sansui Electronics has announced a new direct -drive table,SR -525, above, with controlled dc motor. Price, about $280.
Another turntable with direct drive that has done wellin a number of broadcast stations is the Sony TTS-3000.That makes highly interesting the announcement bySony, at the NAB show in Las Vegas, that a new direct -drive Sony table, with fantastically good speed stabilityclaimed, is just going on sale in Japan. It will reach thiscountry in the near future-Sony will not yet say when.
Also adding impetus to the swing to the direct -drivetable are models from Sansui Electronics Corporation.Originally concentrating on the hi-fi market for turn-tables, Sansui is now actively marketing the machines tobroadcasters as well. The firm has announced a newmodel, due soon, the SR -525, with a claimed flutterfigure of 0.03%. Price will be about $280.00.
U.S. Pioneer Electronics Corporation is another firmwith a turntable on the way aimed at "hi-fi" per-formance for broadcasters. It uses a novel motor basedon Hall Effect elements, which form a brushless dcservo -controlled drive. Price will be in the $250-$300range. So broadcasters with a need for this kind of turn-table are rapidly getting a wider choice.
It's not for everybody
But the direct -drive turntable is not for everybody. Forexample, the Top -40 station that is running a flock of3 -minute tunes every hour in a tightly knit pattern of DJpatter and commercials must have a table that starts onthe instant, with plenty of torque right at the beginning.With so many starts in the course of a day, a rugged,simple mechanical construction becomes highly desir-able.
Highly admired in a large number of stations (with awide variety of formats) for ruggedness, quick starts,long-term reliability are these ."standards": Harris(Gates QRK, RCA Russco. * As one engineer said abouthis Gates CB500, "two drops of oil a year is all I've everdone for it;" and the same sort of evaluation turned up inBM/E's survey for the others, too. At a guess, there areseveral hundred tables of this kind out there for everyoneof the new direct -drive tables.
Over one grand-the super -machineThe third class of turntable is currently represented
mainly by one brand-the imported EMT (from GothamAudio in New York). It's price of around $1500 impliesextreme mechanical sophistication, and that is what anumber of broadcasters want. Very long term reliabilityis acknowleged, and a number of users particularly likethe cueing method, with a standard cue lead laid out anda muting relay that "waits" for the cue lead to pass. (Seebox for further description.)
One engineer likened his EMT's to high performancesports cars that need occasional expert tune-ups for theirtop performance-which is "top" indeed.
Another, in contrast to all the others, did not like thereaction of the table to the cueing methods used in hisstation. Although no careful analysis of this complaintwas possible, it does suggest that the prospective pur-chaser of a turntable try out on it the cueing proceduresused in his station, or imposed by his format. Evidentlythese vary considerable from station to station-or even,as BM/E was told about one station, among differenton -air men and engineers. BM/E
*Other brands with wide acceptance include Microtrak, Sparta, LPB; mostof these have generally been made, under a "private label" arrangement, byRussco or QRK.

Discover Single System SoundSuper -8 Movies
with the New Beaulieu "5008S"For the last 10 years, Super -8 film
has been "silent". Without sound, yourSuper -8 movies were "incomplete".
Today, there is "Ektasound" film,a revolutionary film which provides themeans to record sound (directly on thefilm) as you're filming. You, therefore,can shoot "complete" movies.
With the new Beaulieu movie cam-era, you will go even further in Super -8.The "5008S" benefits from the advan-ced technology provided by Beaulieu:an image with a professional touch, andnow sound with a high quality level.
Professional Sound QualityPop in a new Super -8 sound ("Ekta-
sound") film cartridge. Focus. Then,plug in the mike. That's all the prepara-tion you need. With the Beaulieu"5008S", you're now ready to startfilming professional quality Super -8single system sound movies.
An amplifier is built into the cam-era which records the sound directlyonto the magnetic stripe of your soundfilm. The camera records high fidelitysound, both in treble as well as bass(frequency response: 50-12,000 Hz ±1.5 dB; distortion: less than 0.75%;signal-to-noise ratio: 57 dB; wow andflutter, attenuated peak: less than0.4%).
The "5008S" modulates the singlesystem sound recording automatically.However, there is also a "manual" set-ting so that you can modulate thesound as you are filming (by using theVU meter).
"XL" (Existing Light) FilmingCapability
The "5008S" has "XL" (ExistingLight) filming capability which is pro-vided by: a super -fast lens (f1.2,6-80mm Angenieux zoom), a longerexposure time for the image (1/40second), and a through -the -lens meter-ing system that sends 100% of theavailable light to the film.
Since many of your sound movieswill be filmed indoors, this feature willenable you to shoot films in the avail-able light of your scene (whether that"light" is bright or not).
From the "Widest" Wide AngleShot . . . To the "Closest"Close -Up
For the lens, Beaulieu turned tothe professional and technical "knowhow" of Angenieux (which suppliesNASA for all their space missions).
Angenieux succeeded in creating anew zoom lens that covers all the focallengths from 6-80mm (a 13.3 to 1
zoom ratio).Imagine such a lens in 35mm still
photography. It would go from a35mm wide angle to a 500mm tele.
In addition, the lens opens to f1.2(an unprecedented feature on a zoomlens with such a wide focal lengthrange).
New Dolly Shot StyleThe power zoom of the Beaulieu
"5008S" is continuously variable. Youcan travel the full focal length range in4 seconds, or 12 seconds (or any speedin between).

To film macrocinematography withthe "5008S", just zoom to 80mm andfocus. At the minimum focusing dis-tance of 2 feet, 8 inches, you get all thelight available since the lens doesn't
ple, at this distance, a postage stamp
(11/2" x 1-1/5" in size) completely fillsthe viewfinder (and consequently, thescreen-when projecting).
Forget the ExposureWith the "5008S", you can concen-
trate totally on framing and soundrecording. The diaphragm operatesautomatically and stops instantly atthe right aperture. (This feature has"Manual Override".)
Lens InterchangeabilityThe "5008S" is the only single sys-
tem sound camera with an interchange-able lens. It accepts 35mm still photo-graphy lenses (by means of an adapter),as well as all 16mm "C" mount lenses.
The choice is yours. You can inter-change an unlimited amount of differ-ent lenses in order to create a certain"feeling" or effect in your films.

Bellow into it, sweat over it, man -handle it. Practically jam
it into the bell of a trumpet. Without overloading. Without distorting.
This AKG D -140E is a super -tough single element, cardioid
dynamic microphone that's sensitive enough for top studios orconcert halls.
Frequency range: 30 to 15,000 Hz. SPL for 0.5% THD: at1000 Hz is 129dB. Its front to back discrimination exceeds 18dB
at 1000 Hz at a sound incidence angle of 180.°The D -140E can be boom mounted or hand held. There are
no grills or openings on the shaft to cause feedback or alter re-
sponse when hand held.
The compact size of the D -140E works on stage or TV too.
While it delivers all the high quality audio a program produces,it's so small it can't hide anybody's video.
The D -140E lets music sound life -like, without any colora-
tion of its own. There's a 12dB bass roll -off filter switch recessedinto the handle to let you reduce the proximity effect. Or retain it,
as the needs of a session dictate.The D-140E's transducer is internally suspended and en-
capsulated by a wire mesh/urethane foam windscreen/shield.So handling noise, dust, wind anc popping won't interfere with
your work.See your professional equipment dealer for the D -140E or
write to us. Before the pressure builds up.

The Editor -In -Chief:
Now you can economically edit on helicalsand automatically transfer in minutes to quadsThe editing system you'vebeen waiting for.Meet the Editor -In -Chief. Ourthrifty new Vidicue 5050.
It defies obsolescence.You can expand from two tothree machines at will. Ormove up in logical steps to acompletely automatic on-line, off-line system whereediting is done on low costhelicals and transferred inminutes to quads.
Easy to learn, and tooperate too. Simplekeyboard entry. Visualdisplay of tape position and al editpoints. Exclusive jam sync, eliminatingforever the need to pre -record SMPTEedit code on tape. A/B rolls, colorframing, special effects switching,time base correction. The works!
Yet this remarkable video tapeediting system is priced far belowcompetition. In fact, there is none.

The importance of Jam -Sync.Our exclusive jam -sync eliminates theneed to pre -lay -down the SMPTE editcode on an entire length of fresh tapebeing used to assemble a show fromother tapes. Instead, during pre -roll,the system time code generator is auto-matically set and sync'd so that timepicks up exactly where it left off - to
the frame. This saves quadhead wear. Tape wear, too.And is also a great timesaver on stop -and -go liveproduction by generatinga continuous uninterrupt-ed elapsed time on thetape.Save your expensive quadsfor other jobs.The block diagram tells thestory. You can edit on-lineor off-line. Do timeconsuming edits or low costhelicals. Edit event timesare stored in the computer
and a punched tape prepared. Usingthis tape, a precisely edited show canbe automatically transferred to quadsin minutes.
Your quads have never had it sogood. Or your pocketbook either.We'd like to tell you the wholestory of our Editor -in -Chief.Why not write or phone today.

66 SEPTEMBER, 1975-BM/E
In 1965, 3M introduced a quadruplex solo- drop-out compensator that has since become the standard ofthe industry. Today, all three networks and thousandsof television stations across the country rely on 3/V. Brandcolor DOC's to bring viewers better picture quality.
But what have we done for you lately?
See us at Video Expo, booth 601Watch 3M's Dicentenniol television series 'From Sea to Shining Seo:' Consult local listing for time and channel.
VVe don'tuit when
Introducing five new video products for broadcast,educational and industrial uses.
Wecould have rested on our laurels after developingour quad color DOC. But we didn't. Instead, we've devel-oped five new low-cost products to help you produce the
very best professional -quality video with your existingequipment.
3M Mini Processing AmplifierThis unit, designated P-50, has on important exclusive
feature: A built-in pulse -cross generator with automatic brighteningthat allows the use of any inexpensive monitor to examinethe critical head switch area for tracking and skew adjustmentsduring on-line operation through an auxiliary monitor output. Otherfeatures include front panel controls for six video signal parameters;horizontal and vertical blanking generator for precise timing, plus areconstituted sync system to allow stable operation with randominterlaced video; operation with both color and monochrome in-puts. Burst or chromes con be switched out to accommodateunacceptably noisy color recordings; and input clomping for excel-lent low frequency and 60 -cycle hum rejection.
3M Bridging Video SwitcherThis is a broadcast -quality unit. It is a highly -
sophisticated 10 -input switcher with momentary -contactilluminated buttons. There is an audio D. A. to eliminateloading, and this unit also provides remote capability.
3M Digital Video AGCThis digital unit is a new concept. There is none
other like it. It can be used in any application wheresudden and undesirable signal level changes occurwithout incurring the unacceptable effects usuallyassociated with AGC circuitry. There is no overshootwith large duty cycles. And calibration/setup is simpleand straightforward. Other important features includea peak white or VIR reference signal; fade -to -blackrecognition circuit for gain memory; selectable attackand release time; and a total AGC range of 15 db, withunitygain under no -input conditions. Suitable for broad-cast, industrial, educational and cable TV applications.
3M Color Bar and Sync GeneratorNow your studio can have a color reference
for a surprisingly modest cost. This unit produces anNTSC 8 -bar pattern and all sync signals just like the veryexpensive units used in professional broadcastingstudios.
3M Video Distribution AmplifiersThis complete line of products suitable for any
video application includes a Pulse D. A. that reformsdistorted incoming sync pulses, and if your applicationrequires, will accept composite video and separateand distribute sync as needed. Then mate this unit withour Subcarrier D.A. that has four independently phase -able outputs, and our totally reliable four -outputAnalog D.A. with cable equalization.
Turn the page for six more 3Mprofessional -quality products.
Quodruplex Color DC CThe 3M dropout compensator is the industry
standard for broadcast VTR use. It replaces color dropoutsin videotape recordings with the correct color video,avoiding the problems of other types of signalcompensation.
Helical DC C and Processing AmplifierOur 3M DP -100 is a complete video processing
system designed to clean up, correct and stabilizehelical scan VTR signals for any VTR format. Correctsfor high or low contrast, inaccurate or washed-out colors, picture jump and roll.
Video Source IdentifierThe VSI inserts a preselected, 8 -character
identification code into any 525/625 composite videosignal which appears on your picture monitors to helpkeep your switching straight and locate video path failures.

Special Effects Generator and Program SwitcherThis 3M SEG 672 performs vertical interval
program switching, dissolves and wipes between sixvideo inputs. The key and mat key feature can be usedto produce many imaginative special effects. Joy -stickpositioner. Many features of more expensive units.
Dropout Profile Recorder
The DPR evaluates video dropout rate andannoyance factor during normal on-line playback, andprovides a permanent strip chart of the resulting profile.The logical companion to the 3M dropout compensator.

Within TeleMation's "525 Series" audio and videoterminal product line, certain units are designatedprecision as distinguished from their broadcastcounterparts. The precision designation is much morethan a simple "marketing label". Precision is a demar-cation assigned through TeleMation R&D that puts aparticular product into a separate, unique attentioncategory, from design concept through manufactureand quality -assurance verification. All this to assurethe buyer that the product not only meets or surpassesall known competitive products in its performanceparameters, but also that it is designed to operate formonths and even years without need for periodicadjustment or any other routine maintenance. Thisphilosophy and practice, then, take the precision unitsin the 525 Series terminal equipment into a quality/stability/reliability realm that is usually associatedwith instrumentation electronics.
TeleMation has used a number of design techniquesin accomplishing the high performance and stabilityachieved by these products. For example, one -percent -tolerance resistors having a temperature coefficientof 2OPPM/ °C are generally used as gain -determiningelements and wherever drift would affect stability.They provide both freedom from temperature driftand freedom from the effects of aging that are com-mon to the less expensive resistors normally used invideo products. Junction matching - each PN junc-tion being matched with an NP junction to cancel thecharacteristic 2.2mvi°C drift of silicon junctions - isalso employed to improve stability and prevent offsetdrift in DC -coupled outputs.
Feedback is extensively used in precision grade unitsas a means of insulating performance characteristicsfrom the effects of component variables. Audio ampli-fiers are typically high -gain op -amps inside 100 -dBfeedback loops, while video amplifiers are typicallytransistor pairs inside 40 -dB feedback loops. In theseapplications, a 2:1 change in the gain characteristicof any active component will have negligible effectson overall circuit performance.
The advantages of push-pull, cascode, and comple-mentary symmetry circuits are exploited to providelow distortion, wide bandwidth, and high signal han-dling capability. Current -sourcing techniques are alsoemployed as a means of minimizing distortion thatotherwise can result from operating semiconductionjunctions over wide current ranges.
TeleMation engineers also have successfully copedwith capacitor leakage (another source of long-termdrift) in the precision series designs. Capacitors areeither operated with minimum DC voltage drop orthe effects of increased leakage with age are other-wise eliminated, as in the TVA -524 and TVA -525video distribution amplifiers where the capacitanceof a small capacitor having extremely low leakagecurrent is "amplified" by a high -gain op amp; theresult-longer time constant, less tilt, and greatly im-proved long-term stability.
Our TVA -525 video distribution amplifier, whoseperformance characteristics are listed below, is a rep-resentative application of the quality and stabilityfactors inherent in the precision series product.

WITH30 DB NOISE REDUCTION AND10 DB EXTRA HEADROOMWith dbx Model 142 noise reduction in the rack, you can: Nearly double the usable signal-to-noise ratio of your cartridge chain, studio
master recorder, line and program amps, full -frequency land lines, and micro-wave links.
Make original tapes completely free of hiss or background noise on open reel,cartridge, or cassette format.
Duplicate tape through three or more generations without audible noise build-up.dbx noise reduction linearly compresses audio signals by a 2:1 ratio at the frontend and produces an exact mirror image 1:2 expansion at the terminous of theaudio chain.
True RMS level sensing circuitry insures perfect encode/decode trackingover a dynamic range well in excess of 100 dB irrespective of phase shifts in thetransmission or storage medium. There is no breathing, pumping, or other colora-tion of the sound with dbx noise reduction, and there are no pilot tones or calibra-tion levels to worry about
dbx Model 142 provides two channels of broad -band audio noise reduc-tion in excess of 30 dB coupled with an additional 10 dB increase in headroomfor all components and lines included within the noise reduction loop.

R -MOD is the logical answer to your requirementfor automating existing VTRs.
The field installable modification kit upgrades yourexisting VTR transport to achieve performance likethat of the newer vacuum buffered drives.
The terviedAnd inTV Broadcasting,its the service behindthe product...that keepsthe product out frontOn the way to selling more than 30,000 Plumbicon* TVcamera tubes, we learned how important Service is to thebroadcaster. The first thing we learned was aboutavailability- No TV station, commercial or educational,can ever afford to shut down an operation while "waitingfor parts." Plumbicon tubes are instantly available, at alltimes, through local franchised distributors and throughAmperex factory sales representatives.
And we learned the importance of the name Plumbiconto TV stations who have come to depend on it as theirassurance of consistent performance and quality.
Because no product is ever "good enough," we taughtourselves to build smaller and smaller Plumbicon tubesthat provide performance standards similar to the original(we're down to 2/3 inch tubes now,) and we learned toproduce tubes with reduced comet tailing, with higherresolution and modulation depth, with extended -redresponse, and with minimum lag. Contemporary cameratubes outperform the original Plumbicon by a wide margin.
We learned that the TV camera user is concerned aboutthe operation of his camera ... not merely about theperformance characteristics of our tubes. So we providehim with a wide range of expert and valuable information,in print and via our field engineers, to help him get themost out of his TV camera -system. Plumbicon userswho are about to install a new camera need only give our
field engineering staff a call and we'll have an expertthere to help with the job.
Our franchised distributors, (your own local business-men,) are carefully selected for their ability to supportPlumbicon TV camera systems with on -the -spot customersupport and service. We, in turn, support our distributorswith two kinds of "seminars" for Plumbicon camerausers. One is on video tape, the other is presented "live"by an Amperex field engineer. The purpose of both is tomaximize the value of Plumbicon camera systems.
Finally, we learned that the best way to deal with warrantyquestions was to design the warranty for the customer'sbenefit - not to protect ourselves ... and even then, tointerpret the warranty in the customer's favor wheneverpossible. For example, a customer may return anyPlumbicor tube for testing (even one that's technicallyout of warranty) and we'll subject it to a complete technicalevaluation at our expense ... and send the customer adetailed engineering report on the tube.
Yes, we've learned a lot about the importance of Servicein the ten years, in the more than 30,000 tubes sold, in the600 -plus TV stations served, since the Plumbicon tubewon the Emmy award. _ittle wonder, then, that thePlumbicon, after all this time, still offers the best all-aroundpackage of performance, price. reliability and serviceavailable. Little wonder, then, people keep on saying,"There's only one Plumbicon."

IT'S TIME YOUCHANGED THE WAY YOU
LOOK AT THINGS.Broadcast people, you've changed. Overthe last few years, you've effectively turnedthe industry on its ear witha determination to pro-vide your public withmore, and more effec-tive coverage. Your re-solve has brought about P10 x 206.

supplying the broadcast industry with high -quality optics for the last two decades, we'vebeen hard at work, developing a family oflenses to expand the capabilities of broad-cast TV equipment...while keeping theeconomics under control.
You are our requirements.More than any
other factor, Canon products are the resultof user inputs. So it's no coincidence thatwe offer the widest, most customized rangeof optical products for the broadcast field-in terms of function and price. From thelightest -weight, most compact (and by theway, most popular) 10-120mm on the market
to an enormously-versatile 32-1070mm withcontinuous zoom and 1.8ii.meter minimum objectdistance.Your require-ments also inspired our

a family of two-lens systemsthat give one camera the versatilityof two at substantial savings. (And we're al-
ways listening for new ideas.)We've invested in you. Because major
optical advances don't happen without a lot
of expensive thinking and heavy experi-mentation.While the dividends are visible in
every Canon product (for example, for some
years now, we've been pioneers in superspectral coating), they've also won usacclaim in the process. Like a special awardfrom the Motion Picture Academy of Artsand Sciences. No less important, our size-able investment in manufacture and qualitycontrol insures that the advances in our labsaren't diminished on the production line.

We could spend alot of time on awe-inspiring technical

rather let our lensesdo their own talking. More

Now you can convert any monitor to a cross -pulsemonitor with VACC's new $345. model CPG-1Cross Pulse Generator. Your monitor requires nomodification. Fill out the coupon below for moreinformation. At the same time, ask for a free copyof VACC's Troubleshooting Chart. This handy wallchart has actual photos showing typical video con-ditions such as normal sync with and without burst,time -base errors, overshoot, clipped sync, and manymore. VACc's chart is a valuable aid when adjust-ing and troubleshooting video problems using across -pulse monitor.
If a video monitor is needed, install a VACc Electro-optical Isolator in a Sony receiver. A engineer orelectronic technician can install a model A-1 in a 12",15" and 17" Sony receiver in less than an hour. ModelAl -A should be installed in a KV1711, KV1722 and all19 inch Sony receivers. You add only one-half poundto your receiver and your Sony can be used as ahigh quality monitor or retained as a reciever bymerely flipping a switch. Isolation is far superiorto heavy transformer isolated monitors and youcan connect up to 20 monitors without trouble-some ground loops if all monitors have VACc iso-lators.

TRYA BETTER SCOOPIC. FREE.
If you're in the news, documentaryor industrial field, chances are you'vealready become attached to ourcamera. (After all, 8 out of 10 TV sta-tions and literally thousands of pro-ducers and cameramen own them.)But now that the original Scoopic 16'sperformance and reliability have con-vinced you what a good camera it is,we'd like to un-convince you. Withsomething better.
Meet the new Scoopic 16M...withall the good features and depend-ability of the original, and more.Starting with more lens, for greaterversatility: a 12.5-75mm Macro Zoomthat focuses as close as 31/i' Rackfocuses continuously to distantobjects. And optically dollies forwardand back, with constant field size.
To keep you in action longer, there'sa more efficient battery/transport sys-tem that runs sixteen 100' rolls on asingle, faster charge. Has even greaterruggedness (though some say that'simpossible). And gives you greatercomfort, too, with smoother operationand better balance.
All this is just the beginning.Because the new Scoopic 16M offersmany features you'd expect in a $4,000camera-at an under $2,000 price.
But why take our word for it, whenyou can prove it to yourself-on-the-job and free. For a limited time, atparticipating Canon dealers you cantry a new Scoopic 16M for a week.With one tiny, friendly catch. Once youtry our new camera, you'll want tomake it your new camera, no matterhow attached you've become to theone you're using. To make the deal

even harder to resist, you'll find yourCanon dealer eager to help, with agenerous trade-in allowance on yourScoopic 16.

studios have considered anything butpneumatic pedestals obsolete. The toughrequirements of day-to-day use hasproven TVP Pedestals to be reliable, flexibleand maintenance free.
Our superior pneumatic counter-balance system is used in all of these. With Tthis, cameras float on telescopingcolumns that glide on ball -bearing races.Camera height can be raised or lowered atthe touch of a finger ... smoothly.
And without lead weights, there's lessweight to have to push around.
The 360° steering is adjustable fromcrabbing to tracking at the touch of a footpedal. This mechanism has been speciallydesigned for quiet operation.
You won't find 8 -inch tires on mostpedestals, but they're standard equipmenton ours. Bigger is better: not only do theyroll easier, but they'll transmit less vibrationto the camera.
If you're worried about maintenance,you'll be glad to know that we've used sealedball bearings wherever possible. The airsystem requires only one -point lubrication,once a year. And everything is designedfor easy access.

Naturally, the noise is reduced. But that'snot all. Dolby compression isstandardized, recoverable compression.By using Dolby encoding instead of theconventional high frequency limitingnormally required during transmission,the station gives the listener at home theopportunity of recovering the fullfrequency range and dynamics of thesignal. Furthermore, depending on theamount of limiting previously used, manystations find that Dolby encoding permitsthem to increase their level -which isgood for both the listeners and the station.

Problem: To wire a telephone into aradio station in such a way that distantand local audio levels are nearly thesame. Do so without buying an auto-matic gain controller. And wire it insuch a way that it is impossible foranytone to forget to disconnect whenthe call is done.
Solution: Many telephones (allthose made by Automatic Electric.)have a transformer circuit whichphases out the microphone at the ear-phone. All you have to do is pick offthe audio for your programming at theearphone. The outgoing siunal (yourphone mike) is attenuated at this point,so that even with a long distance calll,both the near and far voice will beabout the same level. In our situation,this system has worked well, espe-cially where we have been recording.The usual vast difference in levels be-tween the two sides of a phone con-versation are too hard to compensatefor manually: an AGC would cause
Flexible, solid-statInput-output configurations are virtually unlimitedwith this modular, building-block solid-state, audioswitch. And . . . this flexibility comes at reducedcost.
Starting with a single 8% -inch by 19 -inch rackframe assembly, the user can build to a 20 -inputby 20 -output configuration through selecion ofplug-in switching and amplifier boards.
Still using the same basic frame assembly, otherconfigurations such as 20 by 5, 10 by 20 cr com-binations in between can be assembled. Greatercapacities, including dual inputs or outputs, arejust as easy ... just add.
Control? ... a snap! pushbuttons, thumbwheels,dials, touch pads ... even a computer.
Performance is outstanding. Using field effecttransistor switching and integrated amplifiers, theSeries 8100 handles -6 to +8 dBm levels throughits balanced transformerless inputs. Flat within±0.15 dB (20 Hz to 20 kHz) ±1.0 dB (1 Hz to50 kHz), crosstalk (better than 70 dB belowoutput), harmonic distortion (less than 0.15%) andhum and noise (85 dB below maximum output)the 8100 compromises nothing for its flexibility.
Best of all, users will really appreciate theeconomy. By specifying the initial capability forany remotely -controlled, switched audio distri-
T Tbution network, the buyer saves 1.1 ..117
penalized later. High reliability solid-state autoswitching costs can be cut to as little as $10 percrosspoint . . . significantly less than competitiveswitching systems.

some pumping and costs too much.But with this hookup, when you hangup the phone, the line hangs up aswell. No need to disconnect yourrecorder or console from the line. Lineisolation is provided by a scrappedradio audio output transformer. Thehigh -impedance side goes to the ear-phone. No pad is needed, and clicksand pops are nil.
27. De -Hissing a CartMachineJohn E. Shepler, Chief Engineer,WACI-FM, Freeport, Ill.
Problem: To eliminate the noise(hiss) of cart machine amplifiers whenthey are not being used. Stations withmultiple machines can find the com-bined noise output annoying at least,and perhaps strong enough to be thecause of a proof -of -performance fail-ure, at worst.
Solution: The modification we areusing at WACI pads the audio outputof the cart machines when they are notin use. Some of the newer machineshave this feature, but many now in
service do not.The process was automated with a
relay and a couple of 10,000 ohmresistors (for stereo). As shown in thediagram, the resistor, one per channel,is installed after the output trans-former, effectively padding the noisebelow audibility. When the Startbutton is pushed, voltage is applied tothe relay, which has contacts to shortthe resistor and restore normal oper-
ation. When the cart stops, the relaydrops out. Normal audio is loudenough to mask the hiss while a cart isplaying. Use a miniature low -currentrelay. Connect it to the Start circuit.For Spotmaster-500 machines, oneside of a 24 -volt relay coil goes to K-1Point 10 of the Spotmaster circuitboard. The other side is wired tochassis ground.
Datavision D-3000Generates Characters...Sm0000th on theCurves!
The most significant feature of any character generatoris the quality of the characters it generates. Simple.Character quality shows in the smoothness of curved lettersand numerals. An obvious "stair -step" tells you that themanufacturer skimped by using less elements in the matrix.
The Datavision D-3000 has 1120 -element characterresolution, as good as the most expensive equipment onthe market, and at significant cost saving. Plus, the D-3000is loaded with other features: two character sizes; twoindependent output channels; 3 speed roll and crawl;character edging; word flash; automatic centering; andoptional D-4000 Random Access Storage System.

switcher is a long reach from the oper-ator's normal position.
Solution: A small 4 x 1 switcherwas placed downstream from the rout-ing switcher in the line feeding themonitor. The switcher is designed toautomatically switch the monitor todisplay the output of any of four VTRs
whenever any given VTR is rolledfrom the operator's remote controlpanel. After a set time the unit auto-matically switches back to whateverhad been pre -selected on the routingswitcher.
It was desired that the circuit onlywork from the remote position (to
avoid miscellaneous switches whiletapes were being cued), and to avoidmodifications to the VTRs. We use anunconnected pair of normally -closedcontacts available on each of theremote Play buttons to control the

switcher.An input NAND gate is used on
each input to provide a fast transitionof the proper polarity to trigger its as-sociated NE555 timer. Each timer inturn controls the length of time themonitor remains on the VTR output inquestion before returning to the sourcewhich has been selected on the routingswitcher. Since KVIQ uses a six -second pre -roll, the timers are set forten seconds, allowing the operator tomonitor the, preroll and the first fourseconds of the spot before returning tothe preset source, by which time thetape should have been placed on the air(or on the Preview buss during dub-bing).
The timer is a NE555 wired as a oneshot. Large values of R11 and C 11 arechosen to give a wide-range of pos-sible delays; they could be chosen togive a highly accurate fixed delay ifdesired. The output of the timer is usedto control the switching transistor,Q11, which supplies current to therelay, see Fig. 2. A set of solid-statecrosspoints could be substituted if de-sired.
