Have been of late listening to channels 1-7 and 15-22, plus the repeaters progreammed in, on my mobile GMRS rig. A lot of activity on channels 1-3-4 7. Channels 4 and 7 have a local school near my house, very short range. Channel 7 is being used by a nursing home, based on the traffic I'm hearing. 1 and 3 have a few users, sounds like family or family businesses, but in Hmong and Spanish, not fluent enough in either to get the gist of the conversations. Never a call sign, so imagine they're all on FRS radios.
Occasionally hear a couple of guys talking on 7, using GMRS callsigns, rarely hear anything on 15 and up except occasional repeater conversations, including my own.
Wife and I use Ch. 8 at home around the spread (.75 acre City Lot in TC area)
Maybe CU on the radio,
