When Windows updates it sometimes changes my KX3 settings. Not exactly
something you would think of when trying to diagnose a problem with the
radio. If your K2 is connected to Windows in any way, that might be the
explanation.

Good Evening,
As I was talking on 20M SSB tonight, my K2/100 started to get a bit twitchy
when I transmitted. The power was set to just below 100W. I started seeing an
intermittent 'High Current' error message, which then changed to a constant
'Hot PA' error. I have an intermittent RFI problem on 20M (which I thought I
had solved), so that might have returned and caused this problem.
I tried matching the antenna with the KAT100. It would not arrive at any
solution - there were no relays clicking. I had to press the 'tune' button
again to stop it. Toggling the power on the rig made no difference.
So I searched the list's archives, and found a thread where Don mentioned the 'CAL TPA'
menu. I found that it was at its maximum setting of 150C - I have set this parameter
twice since building the radio 7 years ago. Resetting it to about room temp fixed the
problem, and the radio now behaves normally. I also checked "CAL Cur", and it's
still set to 3.50.
So, it is working again, but why did the 'CAL TPA' setting go to it's max? Is
there a known problem? Maybe it's a glitch from the RFI, but I thought I should
ask just in case there is something else I should check.
Thanks. 73,
