[Elecraft] KPA500 and KAT500 Ports

[Brian Alsop]

The other thing that seems to be missing.  The K3 ought to be switching 
the antenna switchbox, not the computer or some other device.

The reason is obvious, the proper antenna will always be connected 
quickly.  The same cannot be said for other approaches.

I used to use computer switching with a transceiver that had no BCD 
output via a logging program.  Pouncing on a spot and transmitting often 
resulted in the wrong antenna still being attached and then hot 
switching of the correct on in line.  Not nice with an amp attached.

If some other slower device has to be used, some kind of inhibit signal 
should be applied to the K3 until switching or switching + tuning is 
complete.
