Barry,
You should be able to tolerate 60 degC measured at the PA transistor
tabs for short periods.
You can read the PA temperature in the Alternate VFO B display.

Thanks Tom and Don for the responses. I'll try a few 15sec FT8 xmit cycles
at 50% (7.5W) into a dummy load while monitoring PA temp. Any guidance on
what the upper safe limit is for PA temp?
