[Elecraft] KSYN3A_transmit_frequency_jumping_around?

[Dave New, N8SBE]

Sorry for the blank first message.  With so many email lists I'm signed
up for, it's hard to keep track of the ones that either bounce
HTML-formatted messages, or just strip it off, like apparently this one
did.  Here goes:

I ran my K3 with the new KSYN3A boards on the MI QSO party for about
10.5 hours yesterday, the first SSB event I've done with the new boards
(prior CQ WPX CW for a couple of hours worked fine, using S&P).

I spend long periods of time camped out on various frequencies/bands,
calling CQ MiQP and working stations.  I noticed a number of callers
coming back to me off frequency by a couple of hundred hertz, and
started 'chasing' them with the RIT, which only seemed to make matters
worse.  When they came back each time, it seemed they were on a
different frequency.

Eventually, I had two different stations tell me (without prompting)
that my transmit frequency was shifting around, and that they were
chasing me around!

One station thought maybe I had mistaken my XIT for my RIT (nope).  Not
knowing what to make of it, and being in the middle of the QSO party, I
wasn't eager to mess around trying to debug it, so I just turned off the
RIT and managed without it.  I still had folks occasionally calling me
noticeably off frequency for the rest of the evening.

I still don't know if the RIT aggravated the situation or not, and I
spend some time this afternoon looking through my Elecraft mail list
archive for anyone else that may be experiencing anything similar, and
turned up empty-handed.

There are two things also to know:

1) I was using the latest N1MM+, but was not using it to transmit, i.e.
I was using the DVR built-in to the K3 instead of function keys on
N1MM+.  In CW contests, I do the opposite, preferring to use the CW
memories in N1MM+.

2) I have the RIT knob set to do fast tuning (on SSB that means 500
Hz/click) when the RIT/XIT are disengaged.

One other observation: At no time did I see the transmit frequency on
the K3 move.  Only the displayed receive frequency moved when RIT was
engaged.

I'm baffled as to whether this is real or not, but this occurred after I
installed the new KSYN3A boards (I have the sub-receiver) without a
hitch.  Maybe the guys calling me had their RIT turned on, and thus were
calling me off frequency from where they spotted me.

Ideas anyone?  I do have the means to monitor my transmit output via a
portable HF transceiver, but haven't tried that yet.  I'm also running
the latest non-Beta firmware in the K3.

73,
