I had great transmit audio with 1.1.3 and limited compression. 1.2.1 has hardly any compression regardless of the PROC setting. I've tried my normal bal input via W2HYI equalizer or mic direct via mic input (front panel). It doesn't matter. The transmit audio was great with 1.1.3 now it stinks. Probably will go back to 1.1.3 tomorrow.
