I have one under my truck seat with the squelch turned up all the way. This way the truckers have to be very close to me before tripping my squelch threshold. The CB world remains a very nasty mouthed airways... Would even make a Sailor blush... It is especially nasty around the major truck stops... Roanoke comes to mind...
The truckers know the road the best and just knowing what is going on directly in front or behind you has alot of merit. My CB radio sits on CH19 all the time. Even the SMOKEY BEAR REPORTS are most helpful...
We use the FRS radios around the camp site or walking through the towns shopping etc... Gatlinburg is a very busy FRS radio town...
