[Elecraft] TS520S and KPA500/KAT500

[Don Wilhelm]

Bill,

Since the 520S is a tube output transceiver, I think you need to tune 
the PA stage into a 50 ohm dummy load so it matches the input of the KPA500.

Yes, then start at low power and bring it up until you have your desired 
power out of the KPA500.
