[Elecraft] K3/KPA500/KAT500 - Band Decoder for Antenna Switching

[N5GE]

I currently have two HF antennae.  One is an NVIS loop for MARS and
the other is a 4 Element Yagi-Uda 5 bander 20m through 10m.

On the KPA500 I have those two antennae connected as follows:

NVIS Loop; connected to antenna port one, which also allows me to
work 3.52 and 3.8MC.

Yagi-Uda: connected to antenna port two.

When I move to a frequency that is tuned on the loop the tuner
switches to antenna one before it tunes.  Switching to a frequency
covered by antenna two causes the KPA500 to switch to antenna two
before it tunes.

Once the tuner has been tuned once to the frequencies you use on any
band it returns to the setting it has memorized for that frequency,
including the output connector that you used when tuning the first
time.
