This is precisely what I had been seeing, Dave. On lyle's suggestion I rolled the MCU back to 4.14 and the FPF to 1.13 and left the DSP at 2.65. The SSB ouput power persisted so I rolled the DSP back to 2.60 and SSB power is back to normal matching CW power again. The improvement was immediate. > Thanks in advance.

At Wayne's suggestion I had done the TX Gain calibration on the beta firmware with no change in behavior. I will, however, bump back up to the beta before SS. Now that I know what's going on I can work with it. 73, de Nate >> -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
