[Elecraft] Using KAT500 With Antenna Switch

[Tom H Childers]

I'm using the KAT500 here with a multi-band NVIS loop for MARS on
port one and several other antennas on port 2 which has switched
antennae on it.  Some of the antennae on port 2 are in the same range
as the MARS antenna, but the KAT500 very smoothly handles the tuning
correctly on both ports.

Couldn't ask for a better tuner.

Thanks to Dick and the rest of the folks at Elecraft for another fine
product.
