Recently arrived 6600M with 2.1.33.39 Smart SDR Software tested using FHM-2 mic and TX audio was fine.  Switched to a Sennheiser e832 boom dynamic mic resetting the mic input to BAL while using a TRS plug adapter and the TX audio was fine for a while and then suddenly it lost modulation.  MIC menu set to MIC, BAL, PROC off, LEVEL up full, MIC gain adjusted full range. MENU Radio: Bias OFF, +20 dB ON. ....HELP!....Any suggestions, please?

Wayne, it was the adapter plug after all.  It was making poor contact.  Tossed it out and replaced it with a higher quality one and now, Oh how sweet it is!  Thanks for the other tips too Wayne.  You're the man. 73 Bob
