Hi again Don, I just finished that. I found the setting to be 143C. something must be bad; possibly R6 or the temp sensor?
So, I set it to the ambient temp (in C), and checked the current limit setting - it was correct at 3.50A. I toggled the power, and it's now working. Power out is OK, and no error messages. I just talked to a guy on OR and he said it sounds good, but that will be all until I understand what is happening. It was cold this morning, so maybe something was stressed as it warmed up (?). I don't have a warm and fuzzy felling about this. That's a big, sudden error in calibration. Thank you. 73, Jim KO5V -----Original Message----- >From: Don Wilhelm <[email protected]> >Sent: Nov 12, 2019 12:03 PM >To: Jim KO5V <[email protected]>, elecraft list <[email protected]> >Subject: Re: [Elecraft] K2: KPA100 Trouble > >Jim, > >Did you check to see where CAL TPA is set in the menu?
