[Elecraft] KPA-500 no RF until power cycle

[Mike Harris]

I don't have a KPA500, however, I did have an occasional problem with 
the K3 on power up.  If I pressed the K3 power switch too quickly after 
switching on the PSU (switch mode) sometimes the K3 would lock up part 
powered.  If I delay pressing the power switch for 3-4 seconds all is 
OK.  Possibly this is caused by the K3 having to settle to an idle off 
state, sort of wake up before requesting full switch on.  Power rails 
caps charged, that sort of thing.

The KPA500 might be the same.
