K1 Keyer Problem

[Ken Wezeman]

I have used my K1 for years without a problem.  Some time ago the keyer
started sending a few random dits and dahs in the middle of a QSO for no
obvious reason.  I let it sit for a few days while I thought about that
and when I tried it again it worked normally. Now it has a new problem.  
The left paddle sends a constant signal like using a straight key.  The
right paddle seems to do nothing.  I tried the paddles on my K2 and they
worked fine.  I tried my K2 paddles on the K1 and I still had the
problem.  So it isn't the paddles.

I have no clue as to what is happening.  I hope someone else does. Any
suggestions?

Ken,

Did you inadvertently change the menu INP parameter to HND?
If that is OK. try reseating the firmware to clean off any possible
oxidation on the leads and socket.
Still did not fix it?  Re-solder R19, R20 and RP5.

HND it was.  I don't know how that could have happened, but it did. I
forgot about that menu option because I never use it.

Thanks for the speedy reply!  It's nice to know that there are gurus
like you out there watching out for us.
