Hi Bob. The radio provides a dry solid state active level low. What I do is put a micro relay on the back panel and an RCA plug like most radios. I never trust the solid state keying circuit. ?Real easy to wreck the key circuit. I drive an amp with mine and works fine. I can send pic of one I've done if that would help. Does yours TX on SSB? That's my issue. It is very distorted like the audio is slamming the balanced modulator to hard.
