[Elecraft] KAT500 antenna selection

[Rick WA6NHC]

Correct antenna selection is controlled by setting up the tuner using 
the utility program.  Each band can select up to three antennas to use.  
One of the options is 'Last Used'.  That may apply to your station.

Antenna selection cannot be determined without using the utility.

If your antennas are multiband, the tuner can be taught which antenna on 
which band(s).

If the tuner is not programmed for a specific antenna on a given band, 
you cannot override it from the front panel, this is logical and 
protects from accidental choices.

Once you have the selection correctly set (SAVE) you can 'teach' the 
tuner on each antenna on each band segment, per the manual. It will 
remember (use save in the utility).

The time you take to correctly program the tuner saves you hours of 
grief later.  It's time WELL spent.  Then leave the tuner set in manual 
mode so it doesn't attempt retuning if something occurs during use (a 
branch brushing a wire, an unfortunate bird action).

I DO suggest that you (after complete setup)  at least glance over to 
the SWR LED display during operation to ensure things are as you expect, 
even after some time of successful use.
