[Elecraft] K3 - erratic keyer behavior serial related

[Stephen Prior]

I'm getting a similar thing here.  I have no KRX3 and have HRD (latest
version) communicating with the K3 at 38400 baud.  If I send a series of
dahs, every so often the dah becomes a dit.  If I send a series of dits then
that seems okay.

The paddle is plugged directly into the K3 and there is no other software
trying to talk to the K3 at the same time.  The connection between the PC
and the K3 is purely serial, no USB interface is involved.  Latest K3
firmware too.  I have not noticed this behaviour before.  It is independent
of both cw speed and rf output.  If I close HRD the problem disappears.
