[Elecraft] KXAT3 Internal Antenna Tuner Question

[Don Wilhelm]

Fred,

The KXAT3 does remember the setting on each band segment.  I cannot 
recall the width of the band segments, but I suggest you do a TUNE on 
the bottom of each band, then move up 20 kHz and do a TUNE again.
When you go back to that same band segment, the tuning combination 
should be recalled automatically with no additional operations on your part.
If you do a TUNE again (at that point in time) the KXAT3 will initiate a 
new tune cycle and throw away the previously remembered values.  In 
other words, do not do an additional TUNE unless you change antennas.

73,
Don W3FPR
