Hello. I have two Johnson 223 tube type CBs, and they both have the same
problem. They'll run fine for a while, then the radio pops and the
receive
drops out. It may be out for minutes, hours or days, and then pop, it
comes
back in. It is the same on all channels. I have been frustrated trying
to
figure this one out for several years now. BTW; it is not an audio
problem
and transmit is unaffected. I have swapped out all the tubes to no avail.

Find someone to check all the tubes will fix it.
