K3: PA and sidetone loss

Chris Gibson-3
K3 #328 was functioning correctly this morning, till suddenly two changes occurred, neither requested. First, the power level in CW dropped significantly - and on checking, I found that the KPA3 was in bypass mode. Second, I lost my sidetone. Experiments with straight key, paddle and keyboard CW program only produced short "dits". Finally, even the "dits" disappeared, and I was left with no sidetone at all. Further checking showed that the sidetone pitch had changed to 000. I reset the pitch to its usual level, and all was well. Could these changes result from bugs in the firmware? I am using the latest MCU 2.46 and DSP 1.92.
