Good morning,
I stumbled upon a Facebook page dedicated to promoting the use of 26.805 MHz FM as a FM calling/working channel, much like 26.915 MHz (and nearby frequencies like 26.885, 26.955, etc) are used for AM calling/working on the lower channel side.
This matches up with the station I heard transmitting the audio recording loop yesterday "Big Grandpa...this is Big Grandpa calling...Las Vegas!" on 26.805 MHz FM 26805 kHz FM 26805 FM. It was clearly a loop or maybe a voice keyer set up...but the guy was transmitting FM!
Yet another frequency to keep an eye out for/ear out for. They actually picked a pretty good frequency too. 26.815 and 26.835 are sometimes really busy...but 26.805 not so much.
Maybe we will see more FM usage within the CB band as well as outside the FM band as time goes on.
