[Elecraft] KPA500 question about cooling

[Dick Dievendorff]

> If you put the KAT500 above the amp the fans run more often, but are able to keep the amp cool enough for most normal uses. K6XX did test this early on with thermometers. It comes up to fan temp more quickly, but settles at the same temp. I have mine above the amp, but the amp can also be above the ATU, which is what I might do except that the cover of my ATU is off most of the time for a firmware debug cable. 

Putting the amp over the ATU helps keep the ATU in place if you are troubled by cables tending to move the ATU. 

I like the look of K3, P3, and KAT500 lined up. I don't need to operate controls on either the amp or ATU often enough to make it a significant ergonomic issue. I do care about the height of the K3 above the desk tho.

 If I were a RTTY contester in the tropics, I would allow more than minimum clear air space around the rig and amp. 

It's a personal choice issue.
