I'm sorry I misled everyone with my mistake, writing "RIT". Imeant the
*main tuning knob*, so both transmit and receive frequencies are being
changed. Try re-reading the question this way:
Same setup, but listening to a signal on the air. "Beat note" is ~500
Hz. I turn the main tuning knob so that the received signal is lower
frequency - say 200 Hz. I transmit. What does the station on the other
end hear, assuming he is also using USB-CW? Does my "beat note" go up
in his receiver, or down?
What I'm trying to understand is this. I've clicked on a cluster spot.
So have a lot of other people, so they are all in a pile +/- 10 Hz. If
I tune down (frequency and beat note, both) what does the station I'm
calling hear? Is my perceived beat note also lower in his RX, or is it
higher? I think it is the former, butwould like confirmation or correction.

There have been some good answers for you. (I saved some to help
others.)
My answer(s) is to the way I read your question(s).
The 'pitch' is the tone you will hear in your earphones, or
speaker, on both receive and transmit (cw sidetone). It is nicely
done in the K3.
BTW, the 'monitor' knob adjusts the cw sidetone level as I recall.
I haven't changed it in a couple years.
Assuming you are in CW mode:
--First, you have selected the 'pitch' that you like to hear.
--You have 'CWT' on.
--You tune a CW signal near enough to see a bar appear on the
'CWT' scale.
--Press 'spot' and the radio automatically tunes the station in to
your selected tone.
--The signal will also be centered in the filter, and centered on
the indicator.
Once you get used to the tone you have selected, you will be able
to tune well to that tone without using 'spot', or without looking
at the display if you are rushed.
However, the CWT indicator is your guide.
And finally, you said,
"I turn the RIT so that the received signal is
lower frequency - say 200 Hz. I transmit. What does the station
on the
other end hear, assuming he is also using USB-CW? Does my "beat
note" go up
in his receiver, or down?"
As others have said, the RIT does nothing to your transmit. But
it does change your receive frequency, so that it changes the tone
you hear. Not to be confused with the 'pitch' control. The
'pitch' control only selects the pitch you like to hear when the
signal is centered in your filter. From then on, you want to tune
the receiver to a tone of that pitch, or let the radio do it
automatically for you.
As for what the station on the other end hears, that is up to that
operator, who will tune to one side of your carrier until he/she
hears a tone that is suitable.
If you are working a station with a radio that drifts in
frequency, you will often need to make a correction to the tone
you hear by using your RIT. That is it's function.
It was a good question. I think you will enjoy it as you
understand the workings.

Hi Pete:
The K3 reads the actual transmit carrier frequency. That's the
suppressed
carrier frequency in SSB and the actual carrier frequency in any
mode such
as CW in which the carrier is transmitted.
Changing the pitch has *nothing* to do with this. It will be the
same in any
case (the K3 adjusts its internal oscillators as needed to give
you the
desired audio tone without changing the carrier frequency).
To be certain, I turned on my frequency counter and checked the
transmit
carrier frequency while varying the pitch. No change.
RIT means *RECEIVE* Incremental Tuning. It has nothing to do
with the
transmit frequency. Indeed, that's the whole point: allowing you
to adjust
the receiver frequency without changing the transmit frequency
in any way.

I'm having a hard time getting my head around this. My radio is on
3507.02 USB-CW, with a 500 Hz Pitch setting. I change the Pitch
setting to
300 Hz, and the display still reads 3507.02. What is this
frequency? The
suppressed-carrier frequency plus the CW pitch? Does that mean
that when I
change the pitch, the radio is actually moving its frequency a
little bit?
A somewhat related question. Same setup, but listening to a
signal on the
air. "Beat note" is ~500 Hz. I turn the RIT so that the
received signal is
lower frequency - say 200 Hz. I transmit. What does the
station on the
other end hear, assuming he is also using USB-CW? Does my "beat
note" go up
in his receiver, or down?
Sorry to be dim.
