[Elecraft] KAT500 Tune Pblms

[Sam Morgan]

I have the same problem with my KAT500, mainly on 160m.
My problem is my antennas sit on a 26'x150' apartment building roof and 
are to close together. I have done all the Choke/Balun fixes I could.

The fix for me is to get the antennas tuned using AUTO,
then when I operate I switch to MAN. It seems to stop the random 
re-tunes caused by rf coming back into the shack on the other feedlines.

so I would suggest you first do all you can to choke of that stray rf 
then try in MAN and see if that helps with your particular situation.


ymmv
