[Elecraft] K3, KAT500, KAP500

[Rick Bates, NK7I]

You can put (either) the KPA or the K3 on the KAT500, it can take the 
weight.  When I used that combo, the amp sat on the tuner, no issues.

However, it's in your better interest to allow nothing atop the K3 AND 
the KPA to optimize cooling.

If you MUST stack them, shim (along the side edges) them to allow for 3+ 
inches of clearance to allow for heat dissipation (venting for the 
fans).  Again, that's not the best situation and should be avoided.  (K3 
on the bottom for easy control access, SHIM, KAT, KPA)

As said; you WILL have a mess of cables to address as well, RF, ACC, 
serial lines, power...  confining that to a small space rarely goes well 
(pull on one, five more follow).

I'd suggest serious thought to come up with a better arrangement.  If 
you use computer control and logging, the KPA/KAT combination don't have 
to be visible (just allow for cooling), and within no more than 6' of 
ACC cable away from the K3...  The computer can change modes, trigger 
tuning etc. via the utility apps (saves a long reach too).
