[Elecraft] KPA1500 S/N 160 delivered today

[Larry (K8UT)]

Bill,

My KPA1500 also defaulted to FAN SPEED MIN = 0, but that is not fans off 
(at least not on my amplifier).

My fans engage at 60c (low), 65c (medium) and 70c (egads).

Is there a menu explanation somewhere about the start/stop temps and 
speeds? I would like a little more hysteresis in the 60c setting: start 
at 60c but continue cooling until temp drops to 50c. That might work a 
little better when running digital modes with long Tx/Rx intervals.
