[Elecraft] KPA-1500 wish list

[K9MA]

Gain control within the KPA1500 just wouldn't be practical. It would 
require addition of some sort of high power variable attenuator. Slow 
feedback to the K3, however, only requires some added firmware. No, it 
wouldn't work with other transceivers, but that's life. Perhaps someone 
would like to design an external box or write some PC software to 
perform that function.
