I don't know if this applies to your station, but if you are
using a level converter circuit similar to the one in Fred's KX3
book -- 10K input resistor to NPN base with a diode to
ground/emitter and a .1 MFD cap between the collector/output and
ground -- this might apply.
I was using the circuit to level translate RS-232 input to an
Arduino. I discovered that the .1 MFD cap so distorted the
signal waveform that it wouldn't decode in the Arduino. Removing
the cap fixed the problem.

I was operating VE4EA in NAQP this weekend...
A couple of people said the CW sounded mushy.
I was running QSK, with N1MM DTR CW Keying using the KUSB.
I noticed, on the sidetone, that it got mushy around 40 wpm.
I don't know Cary's firmware rev. Is there a fix for this?
(This is with RIT off).
Interestingly, I also used the K3S at VY1AAA, at the same speeds. No
issues.
Did anyone notice this on the sig? Is there a later firmware that
addresses his issue?
