[Elecraft] KPA-500 high gain modification?

[Oliver Dröse]

Great Alan, nice idea with the manual! ;-))

Anyway, a very big part of this world's ham population is not bound to FCC 
rules. So no need to make it public how to modify, just publish the 
schematics or send them out on request without pointing out something and 
Elecraft should be safe?

My KPA500 is serving me very well on my remote station so also no chance to 
take the PA apart again and have a look myself and just buying a second one 
without knowing it is possible might be a bit too expensive to find out. 
;-)) But I would buy a second KPA500 in a heartbeat if I knew I could modify 
it for 10 watts drive for full output!

73, Olli
