The following is an independant review of this base microphone, found during a search of the internet: Power amplified CB microphones have been around almost as long as CB. Originally, most price-point CB radios did not have enough microphone amplification to reach 100% modulation levels with normal voice.
People added amplified microphones to give the extra talk power they wanted in a lower cost radio. As electronics improved and became less expensive, it is difficult to find a radio that will NOT easily hit 100% right out of the box.
Still, amplified microphones are popular since are able to keep the mic a comfortable distance away from your mouth and still easily hit 100% or more. Some people over-drive the radio input with their amplified microphones to increase talk power. Since radios have an automatic mic level limiter in them, this means that although you drive the audio harder than needed, the internal circuitry keeps the audio level low enough to prevent over modulation, but when you are quiet, will allow some of the quieter audio to pass through with nearly the same audio levels.
