More information: RUMlogNG seems to be part of the problem.
Today I was able to relax and watch decode of a RTTY (KL7RST
running contacts). I noticed that the K3 was doing a good job of
decoding the RTTY at all times (but wow, the screen is small).
The P3/SVGA was losing characters making the decode unreadable,
as was RUMlogNG. If I quit RUMlogNG, the P3/SVGA stopped
dropping characters and seemed to be showing the same decode as
the K3.
Perhaps someone who know how the characters get from the K3 to
the P3 can shed some light on what might be going on.
I'll ask Tom, DL2RUM in his support forum.

RUMlogNG can use the RTTY support built in to the K3 via the
RS-232 link. It works well for transmit, although given the
number of times I had to repeat my call, I wonder if there was
a slight frequency difference between the audio coming in to
the computer thru the sound card from the radio and the
transmit frequency. It seemed like there was enough of a
difference that the running OP had to fine tune my signal to
decode it.
I did center the CWT tuning indicator on the K3, and when I
turned on Dual PB, the computer was getting the signal on the
right frequency.
My big problem was on receive. I never got the radio to cleanly
decode. It missed almost all the call signs, regardless of
strength of the signal. I tried using fldigi, which did work,
and cocoaModem which seemed to decode better than fldigi. I
ended up using cocoaModem and logging manually. (Next time I'll
probably steal the VGA screen from the P3 and use it as a
second screen on the computer so I can see all of both programs windows.)
The question is, what am I doing wrong with getting decoding to work on the K3?
