[Elecraft] KAT500 and KXPA100 tuner problems

[Gary Gregory]

Same here.....and i have only used the supplied reference material, use SSB
90% of the time, non resonant antennas as well as a tribander.
I "teach" the kat500 when i first set up the run in "manual" mode.

The one time i had sudden "tune" issued the culprit was one leg of the
ladder line broke at the antenna.

Nuff said from me i guess
