[Elecraft] KPA500 Temps?

[cx7tt at 4email.net]

For the NAQP cw party this past weekend, I ran low power. Rather than
'stress' the K3s with 100W, I chose to run 6W thru KPA500, giving me 100w.

During a one hour run period, 125+ Qs on 15m, I noticed the KPA500 temp
at 51C which surprised me. Idle temp in the shack is generally around 33
to 35C. I expected much lower temp at 100w output.

Why the higher temp and is it not related to power out?
