[Elecraft] KAT3 tuning per Antenna

[Tom Hammond]

Hi David:

The KAT3 will NOT re-tune unless you TELL it to do so!

When changing from one band/antenna to another, the KAT3 will select 
the last-used
L-C set for that band/antenna and use that set unless you press the [ATU TUNE]
button to force it to retune.

So, assuming you have already (previously) told the KAT3 to select a set of L-C
values for a band AND for a certain antenna (connected to ANT1 or ANT2) then
going back to that band and antenna selection will result in the KAT3 choosing
the last-used (supposedly suitable) set of values.

If you have two different antennas (connected to ANT 1 _and_ ANT2) and EITHER
of these antennas can be used on a certain band (say both a vertical 
and a dipole,
capable of operation on 40M), then the KAT3 will remember the L-C 
values used for
EACH antenna and they will be selected FOR that antenna (whichever antenna is
selected) when you switch to 40M.
