Why do mostly all VHF radios range start at 136 Mhz.... isn't that for airband ONLY? I'e never heard of FM in this range. Thanks.
Jacob , civilian aircraft is 108.000 to 136.000 mhz. AM if you weren't aware....Why do mostly all VHF radios range start at 136 Mhz.... isn't that for airband ONLY? I'e never heard of FM in this range. Thanks.
Well, yeah...but I'm a little behinder sometimes,lol.The aircraft band in the US was expanded up to 137 MHz several years ago.
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.
This is one of the most complete lists of wireless mic data I've seen,There are wireless microphones that are FM txers up in the 171mhz area, maybe higher. Big cities w/ news rooms and remotes (the news van) has wireless mics in the 400mhz range. I heard someone practicing in ATL (from Lithia Springs, GA). That mic was at 450.0725, I think. Shoulda wrote that one down. May have been NBC 11, or AccuWeather.com.

Not really, The original OP asked about aircraft freq range so that's what I gave him,and someone posted something about quoting rules(and don't know where that came from) then someone ELSE asked about wireless mic so that's what I gave him SO....how am I off topic?? :evil:450/455 would be an IFB not usually a wireless Mic.
And we are way way off-topic as to what the OP originally asked
True, pretty scarce here tho...FEMA has big network in the 136-144 band. Also a lot of navy FM shore stuff there. It's either feast or famine depending on where u live. It's an interesting section of spectrum to listen to.
then someone ELSE asked about wireless mic so that's what I gave him SO....how am I off topic?? :evil:
Btw bill, I don't see a administrator tag for you?
