Hello.
I have tested over 200 Baofeng radios, some under other names.
The receive may be bad, but transmit is fine.
And, there was a CB/FRS unit out a while back.
It had a fixed antenna for the FRS side and a standard SO-239 for CB, they work well.
FRS is used for things like parking lots and the like, ultra short range.
When you have 50 trucks in a truck stop you have a problem with not being able to hear the other trucks, too close.
But, FRS solves the problem.
Backing, the spotter can carry the talkie.
.5 watt is more than enough in this case.
