[Elecraft] Drifty power k2-100

[john]

I have been using my K2-100 for some months, and have been enjoying it a 
great deal. I recently began driving a linear and noted that the output 
power drifts quite a bit. This is not something that's noticed during 
"barefoot " operation but becomes noticeable when driving an amp.

If I set the power at about 70watts, and TUNE/Display into a dummy load
for about 10 seconds, I can see the power drift to 72, 74, 69, 72 all 
within that
span of time. It seem random, and is not a drift, but rather jumps up and down
every few seconds. I note the difference on the K2 panel as well as the 
output wattmeter.

I thought the supply may not be hefty enough, so I connected it to a 35 
watt linear supply and it made no difference.

Any ideas?  I've changed external supplies, cables, load ... heck, I even 
read the manual!
