[Elecraft] Heat related issue

[James Kern]

Shade definitely can help. I had this happen during a field day a few years
ago with some older tube gear. It worked great all night. As soon as the sun
came up and it started getting brutally hot again, the receiver heard less
and less. When I got the receiver home after field day, out of curiosity I
plugged it in - it worked as normal.. Still does.

Yeah Steve, there is a fix, it is called shading the Radio!

You probably exceeded the temperature limits of inside components.

I had a tuner that kept getting out of adjustment at Field Day one year. 
Finally, I realized that the sun angle had changed to bear directly on the 
dark case and the inductor was heating up and changing value. Put some shade
over the rig by moving it on table and everything went back 
to normal.
