It works out of the box. Audio level is fine. No distortion, very clear. Audio response is flat. It is not filled with high or low frequencies. No motor boating. (RF getting into mic circuit) Well worth the money.
This mic is solid and sturdy, and has a small PTT button. It has good audio out and good mic pickup. Adjusted the mic gain a touch lower on the radio to avoid overdriving the audio signal. No lights or bells and whistles but appears to be waterproof as well as rugged.
