Frequencies Associated with BAOFENG Hand Held Transceiver

Frequencies Associated with BAOFENG Hand Held Transceiver
The purpose of this document is to provide additional frequency coverage information for the BAO FENG multi-functional, hand held transceiver, not necessarily found in the user manual. Many people own this radio to pursue their interests in Ham Radio. I realized however other people including myself have additional interests in using this radio beyond the 2 meter and 70 cm band, so besides the amateur radio coverage, other interesting land, sea and space communications are available too. This extra frequency coverage makes this radio even more enjoyable… even from just a listening stand point!
As you will see, this is a work in progress. Much of the information was derived from other resources so reader beware. I look forward to your comments and suggestions.

The Radio Spectrum / Frequency Allocation
Use of radio frequency bands of the electromagnetic spectrum is regulated by governments in most countries, in a Spectrum management process known as frequency allocation or spectrum allocation. Radio propagation does not stop at national boundaries. Giving technical and economic reasons, governments have sought to harmonize the allocation of RF bands and their standardization.
A number of forums and standards bodies work on standards for frequency allocation, including:
International Telecommunication Union (ITU) European Conference of Postal and Telecommunications Administrations (CEPT) European Telecommunications Standards Institute (ETSI) International Special Committee on Radio Interference (Comité international spécial des perturbations radioélectriques -
CISPR)
These standards bodies have assigned frequency bands in three types of allocation:
No one may transmit: frequencies reserved for radio astronomy to avoid interference at radio telescopes
Rev BNov 29, 2012
Frequencies Associated with BAOFENG Hand Held Transceiver
Anyone may transmit, as long as they respect certain transmission power and other limits: open spectrum bands such as the unlicensed ISM bands and the unlicensed ultra-wideband band, and the somewhat more regulated amateur radio frequency allocations. Often users use a "listen before talk" contention based protocol.
Only the licensed user of that band may transmit: the licensing body may give the same frequency to several users as a form of frequency reuse if they cannot interfere because their coverage map areas never overlap.
High-demand sections of the electromagnetic spectrum may sometimes be allocated through auctions.

70-Centimeter Band
The 70-centimeter amateur radio band is a portion of the UHF radio spectrum. This band is used by amateurs engaged in emergency communications where portable and mobile radios are frequently used. Many such radios have dual-band capabilities, operating on both the 70-centimeter and 2-meter bands.
Band Allocation
The band allocation varies regionally. In the United States,[1] Australia and Trinidad and Tobago [2] the band ranges from 420 to 450 MHz with some geographical limitations; in Canada, the band is only 430–450 MHz; in the UK, amateurs are allocated 430–440 MHz. By international treaty between the US and Canada, operation in the portion of the band from 420 to 430 MHz is prohibited north of Line A,[3] which runs just south of the Canadian border from Washington state to Maine, and east of Line C, which runs from northeast to southeast Alaska.

Family Radio Service
The Family Radio Service (FRS) is an improved walkie talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. It does not suffer the interference effects found on citizens' band (CB) at 27 MHz, or the 49 MHz band also used by cordless phones, toys, and baby monitors. FRS uses frequency modulation (FM) instead of amplitude modulation (AM). Since the UHF band has different radio propagation characteristics, short-range use of FRS may be more predictable than license-free radios operating in the HF CB band.
Initially proposed by Radio Shack in 1994 for use by families, FRS has also seen significant adoption by business interests, as an unlicensed, low-cost alternative to the business band.
Worldwide, a number of similar personal radio services exist; these share the characteristics of low power, operation in the UHF (or upper VHF) band using FM, and simplified or no end-user licenses. Exact frequency allocations differ, so equipment legal to operate in one country may cause unacceptable interference in another.

General Mobile Radio Service
The General Mobile Radio Service (GMRS) is a North American land-mobile FM UHF radio service designed for short-distance two-way communication. It requires a license in United States but can be used license-free in Canada. The United States permits use by an adult individual who possesses a valid GMRS license, as well as his or her immediate family members. [1] Immediate relatives of the GMRS system licensee are entitled to communicate among themselves for personal or business purposes, but employees of the licensee, who are not family members, are not covered by the same license.
GMRS radios are typically handheld portable devices much like Family Radio Service (FRS) radios, and share the FRS frequency band near 462 and 467 MHz. Mobile and base station-style radios are available as well, but these are normally commercial UHF radios as often used in the public service and commercial land mobile bands. These are legal for use in this service as long as they are GMRS type-approved. They are more expensive than the walkie talkies typically found in discount electronics stores, and are generally considered higher quality.

2-Meter BandRev BNov 29, 2012
Frequencies Associated with BAOFENG Hand Held Transceiver
The 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising frequencies stretching from 144.000 MHz to 148.000 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania)[1] and from 144.000 MHz to 146.000 MHz in ITU Region 1 (Europe, Africa, and Russia). The license privileges of amateur radio operators include the use of frequencies within this band for telecommunication, usually conducted locally within a range of about 100 miles (160 km). Because it is local and reliable, and because the licensing requirements to transmit on the 2-meter band are easy to meet in many parts of the world,[5] this band is one of the most popular non-HF ham bands. This popularity, the compact size of needed radios and antennas, and this band's ability to provide easy reliable local communications also means that it is also the most used band for local emergency communications efforts, such as providing communications between Red Cross shelters and local authorities. In the US, that role in emergency communications is furthered by the fact that most amateur-radio operators have a 2-meter handheld transceiver (HT), handie-talkie or walkie-talkie.
Band Allocation
The Radio Regulations of the International Telecommunication Union allow amateur radio operations in the frequency range from 144.000 to 148.000 MHz.

Frequencies Associated with BAOFENG Hand Held Transceiver
136-137 MHZ is somewhat newly assigned (10 years ago…that’s the bureaucrats for ya!) to include more channels, however the
communications are AM and not FM.
“Along with the Air Line Pilots Association, the Air Transport Association, and the National Business Aircraft Association, Inc., this
action was found to be consistent with the FAA's three-phase plan to implement 25 kHz channel spacing in the 118-137 MHz band,
which creates more radio channels for use by pilots. These organizations also noted that users of older radios would have limited
access to FAA air traffic control channels, would experience flight delays in FAA controlled air space, and would be unable to utilize
newly available aviation frequencies in the 136-137 MHz band”.
“US244 The band 136–137 MHz is allocated to the non-Federal aeronautical mobile (R) service on a primary basis, and is subject to
pertinent international treaties and agreements. The frequencies 136, 136.025, 136.05, 136.075, 136.1, 136.125, 136.15, 136.175,
136.2, 136.225, 136.25, 136.275, 136.3, 136.325, 136.35, 136.375, 136.4, 136.425, 136.45, and 136.475 MHz are available on a
shared basis to the Federal Aviation Administration for air traffic control purposes, such as automatic weather observation stations
(AWOS), automatic terminal information services (ATIS), flight information services-broadcast (FIS-B), and airport control tower
communications”.
Space/Satellite
The Satellite Band
The frequency band between 136 and 138 MHz was, at one time, reserved for use in space research. Many early satellites had transmission frequencies in this band, and the frequencies above 137 MHz are still used occasionally by new satellites.
Because of history, transmissions from older satellites can still be found in the lower half (136-137) MHz of the band even though it has lost its reserved status.

Additional Supported Frequencies: 65-108 MHZ includes Broadcast FM Band 88—108 MHZ The use of an external antenna will greatly improve your reception. To connect the radio to other antennas you must use a
SMA (Sub Miniature version A) female type connector. One option is to use the arrangement located at this website: http://www.ebay.com/itm/20in-UHF-SO239-female-jack-to-SMA-female-with-nut-Pigtail-Jumper-cable-RG316-/150928485000?pt=US_Radio_Comm_Coaxial_Cables_Connectors&hash=item232409ea88
Speaking of antennas, here is a cheap antenna project for those who want to build a 2 meter antenna…just follow this link and the 3 page instructions found under the title Build a 2 Meter Vertical Antenna.
