[Elecraft] KPA100 CAL tPA

[Lutz Pflughaupt]

Hi Folks,
my problem:
After finishing all adjustments and calibration (also CAL tPA) without any 
problems, I wat to recheck the CAL tPA. Now on my display only " tPA  0C" 
shown. Is not possible to change temperature by VFO-knob.
Many thanks Lutz (DL7AVC)
