[Elecraft] K3 temperatures?

[Sam Morgan]

bingo op error  :-/  (why am I not surprised?)

room temp was 27.7 *C* not *F*
although it had actually been 20F outside earlier that morning

Also, thanks for the calibration tip for the PA & FP temps
I found they were both many degrees higher than actual room temp
