[Elecraft] K3 problems

[Julius Fazekas]

I've had a number of things crop up since trying to get on RTTY. There may be no link to trying to get the rig going on FSK, and the issues are noted in CW mode (my primary activity).

There have been several one-time error messages. The most recent one being: E 0444A7 ERR DSE. 

I've received overtemp warnings on 160, even though I had not been transmitting on the first key down. I've checked the PS, one that I've been using for years. It is metered and the output voltage does not waver. I've checked it with a Fluke in Rx and Tx, and it reads 13.4VDC/13.3VDC respectively. The K3 internal meter reads 13.3 and 12.2! That doesn't seem right.

Also, I seem to have lost control of my RF Gain pot. It does not function in AGC, either F or S. Sometimes I can get it to work in AGC-OFF, cycling the radio on and of seems to place it back in the non-functioning mode as does changing bands. I've put all of the AGC settings back to factory default. Same problem.

I'm using the last official firmware release 2.78 and whatever the associated DSP firmware was. 

It might be something blatantly obvious, but I'm missing it. Any suggestions before I go batty?

Thanks,
Julius

Wanted to put the second Rx in, but with this weirdness, I'm holding off.
