[Elecraft] KPA 500 Question

[Jim Brown]

> I have cables that control the amplifier for each radio.

By default, the KPA500, KPA1500, and KAT500 all have near-instantaneous 
frequency-detection. They switch very quickly to the right band, and the 
tuners will recall previous antenna tunings for the detected frequency. 
All it takes is a dit or a tap on the mic. That's in addition to the 
front panel band switches. I own all three, and have never used an AUX 
cable with any of them.
