I experienced this pinched audio problem this weekend. Using the current beta firmware, I noted severely pinched transmit audio (using the transmit monitor). It occurred on some bands but not all, and was present sometimes on only one of the sidebands (i.e., when switching sidebands the audio pinching was gone, and returned when switched to the original sideband).

The problem disappeared upon reboot.

Today using SSB on 40M my K3 came up with pinched audio, the other operator
asked me to take the "clothes pin" off my nose. Full (and good) audio was
obtained with a power cycle. I was told that signal strength came up
significantly after the power cycle.

Scott,

I experienced this problem one time. Your description of "pinched" audio is exactly what the other station told me. It was just after I installed a new firmware upgrade, but I don't remember which one. Another new update was available and I installed it. I have not had the problem again. I would suggest downloading the current firmware version and try again.
