I've had the same thing happen a few times with my K3 on SSB. First 
time it happened it made me jump as the audio volume was so loud. 
It's not consistent, but seems to happen more frequently with longer 
TX periods. I do use HRD most of the time with my K3+P3.

It might only happen once a week with me. Since it seems to be 
sporadic, I wonder whether there is some kind of timing window for a 
firmware defect. Say, a combination of commands from HRD plus PTT 
on/off plus firmware timing.

Fortunately, I tend to operate more CW than Phone, so at this stage 
it's just an occasional irritation. But it would be nice to get this fixed.
