[Elecraft] K3/KAT500

[Don Wilhelm]

Knut,

The KAT500 in manual mode will recall the tuner settings that were last 
used for a particular band segment and antenna.

Hence the strong suggestion that you "train" the KAT500 - set it to AUTO 
and do a TUNE on each band segment and each antenna that you intend to 
use for that band segment.  You do not have to repeat that unless you 
change antennas.
Once that is accomplished, put the KAT500 into MANUAL - it will not auto 
tune, but it will recall the settings for that band and antenna 
automatically.

If you leave it in AUTO mode, there is a chance that it will detect a 
false high SWR and attempt to tune when you transmit.
