GMRS/FRS Channel 7 Interference

[afchev]

Can someone monitor GMRS Channel 7 (462.7125 MHz) and tell me what you hear? I usually scan GMRS when I am out and about around town, and for several days now I can hear what sounds like some sort of data packet transfer or something similar (for lack of better terminology.) Just curious as to what it might be. Can be heard all around the city. When I get a second I plan on hooking up my RTL-SDR to see what frequently its actually on as I suspect its close enough to 462.7125 MHz to be causing some bleed over.

And I mean within Las Vegas as I've just realized this is a statewide forum.

Nothing on that page sounds similar. The best way I can describe it is like ACARS or APRS just a different tone.

Best I could do at the moment is a phone recording.
