Recorded during a big band opening...

Didn't sound like big band music to me. ;)

Ch 19A is a good place to "hide out" as there is a lot of bleed over from Ch 19 in most places. If you are away from highways it stays pretty clear.

Been noticing a lot of "A" channel AM activity lately. Not so much Class C stuff anymore other than the local data on Ch 23.

Almost every time there's a band opening and there's activity on the lower channels (almost always AM voice traffic), there's also AM voice on the A channels 26.995 27.045 27.095 27.145 27.195.   27.145 MHz and 27.195 MHz seem to be the most popular...but I have heard folks chatting on 26.995 MHz and 27.045 MHz as well.  27.095 suffers from QRM from channel 11 27.085 MHz (just like 27.195 suffers from QRM from channel 19). 

It makes sense too - hiding on one of the five A channels vs. using an out of band channel is probably better as far as antenna performance goes (presuming the CB antenna you're using is tuned for the center of the band, which, of course, is 27.185 MHz ;)).   That being said, the low channels - 26.515 MHz - 26.955 MHz - are often just as busy when the band is rolling as they say.  The frequencies above 26.6 MHz or 26.7 MHz seem to be the most popular, see the channels that are "down one band" from the popular AM DX frequencies (the obvious exception being 26.905 MHz and 26.915 MHz, both of which are very popular when the band is open).  26.955 MHz seems to be used by truckers and hobbyists alike.

27.255 MHz has had some data on it during recent band openings...although nothing strong enough to overwhelm the voice traffic on frequency.  26.995 and 27.255 are the two frequencies most commonly used by the serious (4-watt or 10-watt) data link and telemetry systems so those are the ones I'd focus on as far as finding hidden data networks within the CB band.
