I've changed R14 to 5.6k to increase mic sensitivity using SSBA=2. I then bought the MH2 mic which is matched to the K2. Reports said I was clipping and degrading the audio, so I set SSBA to 1. Quality is now fine. Can I assume that the MH2 is matched to the K2 with R14 at 1k (as original) and SSBA=2? Thanks David G4CWB
