You can use them with most modern cb's that receive without the mic,
mc60a amplifier does not have much gain, output is low compared to other amplified mics.
This is the truth!'Great audio' can mean different things to different people. In most cases, it will involve modding the radio ('Goldfinger's audio mods'), proper alignment of the radio, and then audio gear (mic, mic preamp, isolation xformer, footswitch, compressor, EQ, etc) that runs from moderately inexpensive to crazy.
