Attention all of you with KAT500 "random retuning problems": Has anyone tried reverting to an earlier FW version? I haven't updated since I first got the KAT500, and I simply do not have this problem. After NAQP is over, I'll start the utility and post the version I'm running. I've seen lots of tests with chokes, baluns, and the link, just never any trying out an earlier FW version.

I am also interested in learning about the resolution of this issue... as a
KAT500 is #1 on my current "wish list" for the shack.  One friend got his
very early on... ordered the day they were first shown at Dayton... I have
never heard him mention any problems.  (I think if he had a problem I would
have heard about it, but am not certain).

I borrowed one from a friend who bought it only for QSO party use when
portable.  I have been using it for several months, on 60 - 10 meters with
my 30' Flag Pole vertical.  I do not need a tuner on this non-resonant
antenna if I am on 30 meters, and I use a different tuner on 80.  I have
made HUNDREDS of QSOs in that time with this setup and I have NEVER seen
the "re-tune" issue that some are experiencing.  I stored tuning solutions
everywhere I operate and then leave the tuner in the manual position.  That
may be the key to not needing or seeing any retuning during a QSO.
