Mike,
You mention this occurs when interior temp reaches 50c (122F). Just
a guess that a device in the SWR ckt or indicator driver is changing
bias with temp and giving a false indication. This is really a
question for Elecraft Tech Dept. I I am correct in my supposition
they, already know about it.
Might be a need for better air circulation for the amp, if so.
