[Elecraft] K2 - Variable Power Out

[Fred Jensen]

I know this has been discussed in the past, but due to the storms here 
on the US West Coast, our wireless access is down and I'm relegated to 
... gasp! ... dial-up, so surfing the archives is sort of a non-starter 
right now.  One of the perils of living in rural areas, I guess.

My K2/100 has developed a variable power syndrome.  I set it at 50W, put 
it in TUNE, and the power out is more or less 50W, but pulses up to 
maybe 90W at fairly regular intervals of about 1 - 1.5 sec.  If I set 
the power much above 50W, when it pulses up it resets, and I get the 
"ELECRAFT" display.  Other than that, it all works find, TX and RX.

I thought it might be the 15A supply I was using so I put it on a 40A 
supply built like a tank.  Still does is, scope says nothing is 
happening to the power source.

I'll take all ideas.  I have a K3, so this isn't a disaster of any 
proportion [in the ham radio sense], but I do use my K2.  If the winds 
blow my antennas down, I won't be using either of them, unfortunately.
