K3 Diversity Question: RIT

Elecraft mailing list
I’ve rediscovered Diversity RX on my K3, and have a question.

Scenario: I’m working folks on 40M CW with a bit of QSB. Diversity is on, and things are working great.

Suddenly I receive an off-frequency call, say up a couple hundred Hz. Normally no trouble, as I just use my trusty RIT control to move up and copy him, so I can keep my TX on the original frequency. But, in Diversity, the second VFO remains on the original frequency rather than tracking with the main RX. As a result, I get two signals until I clear the RIT.

Am I missing something? I really would like BOTH receivers to track the RIT in Diversity.

73, Tom W4KX

I don't know which contest software package you may be using. If you're
running N1MM+ Logger the solution to this dilemma is to equalize the A
and B VFOs at the beginning of the run and then turn on Split mode. Then
your transmitter will be locked to the VFO B frequency and the receiver
can be tuned with the big knob rather than the little RIT knob. This
works fine in Diversity mode and I use it all the time for running. N1MM
also has a nice configuration feature that will automatically retune the
receiver to the TX frequency every time you log a station (at least if
you're using ESM).

Yes, you have to lock the VFOs. That is a menu only (or macro). What I have
done is to program a macro into PF1 that does A->B, lock VFO, Turn on
Diversity. RIT works fine, both RX track.

It occurred to me that might be the case after I sent the message. I'm a
die-hard contester and have the tendency to view things through that
filter. It's easy enough to simply re-tune the receiver when necessary
to return to your transmit frequency, pretty much exactly like you'd
have to do with the RIT knob. You can also do it without a manual
re-tune. If you're running split and tune the receiver  (VFO A) slightly
off your transmit frequency you can easily return the receiver to the
transmit frequency by executing two front panel key presses: A/B
followed by A>B. This first puts VFO A on your transmit frequency and
the second equalizes the transmit and receive frequencies. You can
easily assign the pair of keystrokes to a single macro and store it in
one of the PF presets. That's what I do with my setup -- I then actuate
the macros using the programmable buttons on my K-Pod. Once you get used
to using the main tuning knob instead of the RIT knob you'll never want
to go back.
