Been looking at a a few EF Johnson CBs from 1970s on E-bay, a couple of NOS. Out of curiosity were EF Johnson's any better with audio clarity on transmit and selectivity of receive than the Japan made CBs of the time. Seems I only see them on E-bay or with an inch of dust on them at a garage sale. I read that they were totally American made at the time. Thx ahead of time.
