Last weekend I took my K2 to the Huntsville Hamfest to help out with the
Elecraft booth there. I had a gel cell battery hooked up to it so folks
could twist knobs, push buttons and see what happened. Several folks
did. Today I turned the K2 on for the first time since then and
strangely I had to retune the KAT2 for all bands on both my dipoles. As
far as I can tell, neither dipole has changed physically. One is an
attic dipole and the other is an inverted vee hung from trees in the
yard. Both are fed with ladderline. The attic dipole uses an LDG BA-1
4:1 balun and the inverted vee uses the Elecraft BL-2 set to 4:1. I had
the inverted vee attached to Ant 1 and the attic antenna to Ant 2. Both
had been automatically tuned by the KAT2 to better than 1.2:1 on 80m
through 10m before the hamfest.
I thought at first that maybe something had reset all my internal data,
but all the menu parameters I've checked, including the filter settings,
are unchanged.
Would some set of button punches have cleared my KAT2 settings while
leaving everything else ok? I did not have an antenna or dummy load
connected to the K2 at the hamfest, but I'm pretty sure I would have
noticed someone doing Tune on all the bands on both antennas!
Retuning the KAT2 worked fine, so there's no residual problem, but it's
a puzzle to me as to how this could have happened???
