[Elecraft] KX3 - CW glitch with KXPD3/keyer?

[Thomas Horsten]

Wayne,

When you sent out the field test firmware I reported back to you an issue
that seems very similar to this - although at the time I was certain it was
a firmware issue. But looking at it now, it could well be this issue I was
having as well, and it was just random that it hadn't shown up before I
loaded that new firmware. After that first incident where it was very bad,
I didn't have it come back at that strength. but I've seen a few
missed/delayed dits and dahs with the KXPD3. So quite possibly it's this.

Would you recommend filing off/rounding the ends of the set screws? Or take
them out and clean them with deoxit, or both?

73, Thomas M0TRN
