[WriteLog] MK1100

This won't solve your problem per se, but may reassure you to some extent-
you are doing it the r-i-g-h-t way. Unlike problems reported by others with
parallel ports, USB etc( bad practice if avoidable) , the MK100 absolutely
does not suffer in that respect, because it does not depend on the timing of
the computer in any way, of which it is independent; that's it's raison
d'etre. I tend to think that your original idea is the correct one, iow a
bad mechanical contact. This could perhaps be in one of the 3.5mm jacks to
the MK1100. If I remember it is rather picky about needing stereo 3.5mm
jacks, even though it doesn't seem to need them electrically.

Check all your terminations and revert I recommend.

I used my MK1100 for the first time in the past UHF contest and was very
pleased with the automatic operation of SO2R, particularly the ability
to have automatic frequency selection via the two parallel ports with
frequency data.  I have them interfaced to all of my transverters.

BUT, something seemed wrong with my cw.  It was erratic, sometimes
skipping a beat.  During the contest I attributed it to a possibly
flakey key paddle. Now with additional testing I find that even if I
complete the circuit manually the string of both dits and dahs come out
erratic.  In other words, if I short the dits side so that all I get is
a constant stream of dits, they come out repeatedly erratic.  Same for
the dah side.

Any clues??  Bad setting?

Thanks
