2012 VHF Radio Template Changes
Narrow Banding2012 VHF Radio Template ChangesMaximizing this ClassNarrow banding is more than just some changes to the radio frequencies. It WILL fundamentally change how we use our radios. Please take the time to work through the slides and practice using the radios during the 4 specified exercises. The exercises will give you a chance to practice using various radio configurations in different situations, both emergent and non-emergent. There is also a quiz at the conclusion of the class, intended to ensure everyone has gained the most important information. As we all know, nothing can be more frustrating on a call than a radio communication that cannot be understood. Taking some time today, could reduce a lot of frustration later.
Class OverviewRED Net ReminderMayday RefresherNarrow Banding BasicsRadio exercisesQuizGoalsCreate a framework suitable for future configuration and expansion between multi-county emergency service areasCreate uniformity between agency radios, so that any member of any agency can pick up a radio and find the frequency needed.Narrow banded VHF in accordance with FCC Regulations.The FrameworkRED NETRed net is the primary SAFETY channel for Benton,Franklin, and now Walla Walla County users.Most agencies have designated positions to monitor this frequency.It remains the LAST in the channel order of all zones for ease of location for the firefighter in a Mayday Situation. (See Mayday Refresher in 2 slides)RED NETRED NET SHOULD ALWAYS BE RESERVED FOR EMERGENCY TRAFFIC ONLY.
IT SHALL NEVER BE USED FOR DAY TO DAY TRAFFIC.
IT ALSO SHALL NOT BE USED BY MEDSTAR OR AGENCIES ASSISTING WITH LANDING AIRCRAFT. Mayday RefresherWhen you or another firefighter with you is:LOSTTRAPPED orIn TROUBLECall a MAYDAY Use the LUNAR (Location, Unit, Name, Assignment, Resources) acronym to identify your current situation.Call the Mayday on your current frequency. If no responseTurn the channel selector all the way to the right. Call the Mayday again. If no response.Turn the channel selector all the way to the left. Call the Mayday again.What is it?Why are we changing to it?How does it impact my use of the radio?NARROW-BANDING 101Narrow-bandingWhat is it?Narrow-banding is an effort to ensure more efficient use of the VHF and UHF spectrum by requiring all VHF and UHF Public Safety and Industrial/Business land mobile radio (LMR) systems to migrate to at least 12.5 kHz efficiency technology by January 1, 2013. The FCC is enforcing this requirement.
Narrow-bandingWhat is the purpose of Narrowbanding? Currently, the majority of UHF and VHF LMR licensees operate using 25 kHz efficiency technology. However, the UHF and VHF frequency bands are congested with limited spectrum available for system expansion or implementation of new systems. The migration to 12.5 kHz efficiency technology will require licensees to operate more efficiently, either on narrower channel bandwidths or increased voice paths on existing channels. This will allow creation of additional channels within the same spectrum, thereby supporting more users.Narrow-bandingWhat happens if we dont narrow-band our frequencies?The FCC is monitoring all licensed users and will initiate fines up to $16,000 per Frequency per Day after January 1, 2013 if required frequencies are not narrow-banded accordingly.Narrow-bandingWill I lose coverage area when I Narrowband?It has been estimated that Narrowband compliance can result in a 3 dB loss in signal strength. However, this rule of thumb is based upon a "plain vanilla" Narrow-banding scenario where a 25 kHz analog system converts to a 12.5 kHz analog system. The full impact of narrow-banding in Walla Walla County will not be known until later this spring.Is this true that the impact is unknown still after we have switched here in walla walla?13There is a clear and definite impact of using narrow banded frequencies. It will be vital that all users follow specific radio etiquette in order to maintain good communication.Impact of Narrow-Banding on Radio FunctionalityNarrow-Banding Impacts onOverall CommunicationsGenerally speaking you should not notice a big difference. However, people who tend to talk quietly or do not project their voice will be more difficult to understand.Everyone is encouraged to project, not yell, into the radio.
General Radio CommunicationsThe biggest impact of narrow banding on the radio user, is the need to speak directly into the microphone. The sensitivity of the radios, and the resulting transmission will require microphones to be much closer to the user.Talk into, not at the radio.
EXERCISE #1The impact of narrow banding on daily radio use.Materials Needed:2 VHF Radios with narrow banded frequencies2 or more participantsStanding outside (not inside), have a radio positioned on each side of a building. Use Common.Perform 10 counts, (1, 2, 3, 4, ) starting with the radio at arms length. Slowly bring the radio in towards your mouth, until the radio or mic is approximately 2 inches from your mouth.Have each participant practice talking on the radio. Notice the difference in volume and communication clarity.Find the distance that provides the best communication.Narrow-Banding Impacts onUse of Directional MicrophonesLanyard mics, boom mics, table-top mics, and even portables will require the user to speak directly into the microphone for best signal transmission.
Using Directional MicrophonesEven with SCBA Voice Boxes, the sensitivity of the radio & the transmission, will be more likely to pick up background noise, rather than intended voice transmissions unless you speak directly into the mic.
EXERCISE #2The impact of narrow banding on emergency radio use.Materials Needed:2 VHF Radios with narrow banded frequenciesSCBA Mask &/or Voice Amplifier2 or more participantsStanding outside (not inside), have a radio positioned on each side of a building. Use Common.Perform 10 counts, (1, 2, 3, 4, ) starting with the radio or boom mic with it positioned where you normally would.Find the position that provides the best signal to the receiving radio.Have each participant practice talking on the radio. Notice the difference in volume and communication clarity.Find the distance and direction that provides the best communication.Try using a radio in the radio pouch, without a lanyard mic.Narrow-Banding Impacts onSignal Penetration into BuildingsSome frequencies (specifically repeated freq.) may NOT penetrate into buildings consistently. Dense construction materials such as wood, steel, concrete, etc. will reduce signal strength.Consider the cumulative effect of the number of floors and depth into a building working against the strength of the frequency. Geographical for us means our direct channels? Or is that pikes and copei? 21Narrow Banded Frequency Penetration 101

TAC Frequencies will be best on scene. May have penetration issues.Building PenetrationNarrow-banded signals DO NOT penetrate into buildings or canyons as consistently as before.Because of this, personnel inside the building should either be on FIRE PRIMARY or COMMON or be on a TAC ??Frequency.If you believe you will be out of radio frequency rangePost someone outside who can make contact with you via a TAC frequency, orNotify the Communication Center, and request they notify you via phone if unable to contact via normal radio communications. (Obviously not during emergency ops.)Would we go to W or X TAC is this happened?23EXERCISE #3The impact of narrow banding on building penetration.Materials Needed:2 VHF Radios with narrow banded frequencies2 or more participantsPosition a radio on the inside & another on the outside. (Ideally use a concrete or metal constructed building.)Using CommonPerform a 10 count from the inside radio to the radio outside, and then visa versa.Using a W TAC FrequencyPerform a 10 count from the inside radio to the radio outside, and then visa versa.Note ANY differences in signal strength and clarity.Are these channels correct24It is critical that all members of all agencies practice radio discipline in order to free up radio air time for other necessary traffic.Radio discipline starts by ensuring you are transmitting on the correct frequency for the task at hand.Go en route on your assigned channel. With 12 agency users and countingWalla Walla Fire PrimaryThe primary function of this frequency is for:Dispatching units Communicating with units on single resource responses or typical EMS type responses.The dispatcher or duty officer shall advise units when to move to a COMMON or TAC Frequency.Incident Command communication with Walla Walla Dispatch (until further notice)Will our dispatchers start assigning channels or is that something duty officers are still doing?26COMMONThis frequency is designated and assigned for Command level incidents and may soon be used by all units to:Advise dispatch Enroute to a scene Advise dispatch of Arrived status Advise dispatch of Available status Units may be directed by Command Staff to move to a TAC frequency for on-scene radio traffic.TAC FrequenciesTAC Frequencies are specifically for task oriented functions on any incident.They should be relied upon solely for operations inside of a building. Additionally TAC frequencies are for communicating with other resources in/and around the structure.Division supervisors or Command (on smaller incidents) should be using TAC frequencies to communicate with units on the operational level.
