While I was sitting at work in between calls, I was searching the public safety bands on my PRO106. I came across a control channel on 794.3125. A search of FCC licenses from the NYS page on rr.com came up empty...any ideas???
794.3125 is a mobile frequency, not a base. There wouldn't be any control channels on that frequency.
GRE built scanners are notorious for 800 MHz images popping up in the upper 700 band. That's almost certainly what you were hearing, the control channel of a nearby 800 MHz system.
