This isn't really a Writelog issue but here is some information that may help.

Setting up for CQP one of our K3s showed these same symptoms. We found the 
following thread which suggests checking for +5V on the PTT In jack.

The +5V check failed and we didn't want to attempt our first SMD repair the 
night before the contest so we swapped this K3 to a CW operating position for 
the contest and had a club member with SMD experience do the repair 
post-contest.

While first connecting cables to the K3 the PTT line to the amp was 
accidentally plugged into the PTT In jack instead of the Key Out jack. We 
theorize that powering up in this state may have caused the RF choke failure.
