K3 Split-Mode CW pressing "Rev" Problem

Howdy K3' people:

I tried out my new K3 attempting to jump into the ZL9HR melee on 40m.

I set VFO-B for my TX freq, way-up from his xmit.
I set VFO-A to listen to the ZL.

I set QSK-full & VOX .

Sometimes I wanted to Rx on MY Xmit freq to see if I was 'maybe' close
to where he was currently listening. And "Sometimes after I did that,
VFO-A, ostensibly the freq I was trying to copy the ZL on, became the
same as VFO-B, the freq I "was" transmitting on.

That is, occasional "REV" press made VFO-A become VFO-B .

Why?

Bob,

That is the way it is supposed to work if you do not have a SubRX in
your K3. Actually with the subRX it works the same way, but there is no
need to use it since you can listen to your TX frequency in one ear and
the RX frequency in the other ear.

So, I do not understand your "why" question. Just hold REV to listen to
the frequency where you will transmit. Yes, the VFOs will swap for as
long as you hold REV. You are always listening on what is displayed in
the VFO A area.

Ah, but I do have a Sub-Rx and likely no clue how to make use of it yet.
Also, I was not using the Cans but rather just the Bose Speakers. I'll
have to try the Heil cans .. might be a nifty way to hear the other
freq.

So, what then is the correct way to work CW split since I have a matched
Sub-Rx in the K3?

And replying to what Dick suggested that I and accidently pressed A>B, I
just now tried to make it happen and all I got was VFO-A became the DX
station where I w as listening. Thus A did then equal B ... where B was
the intended XMIT freq .. it was now the DX station AND also still the
xmit (bad) in a pileup

What I saw was B original was 8kHz up from the Dx and was my correct
xmit. A was the DX freq and where I wanted to RX.

Pressing "something", albeit the intended button or not on my part, put
B over A ... B was the TX (for split) and now A was also the RX, having
over-written the DX freq where I wanted to listen

confusing to write .. but I can't duplicate the results you lined-out

Hi Bob,

That should not happen. The problem could be related to your computer software refreshing VFO A while you are holding the REV button. What software are you running?

I don't know if mine is the effect you're seeing but for K3 #642,
tapping the buttons too lightly [to keep the radio from moving] will
often "beep" but nothing happens, and much less often, will cause some
other function to occur. Once I secured the radio with that double
stick moulding tape on the feet that was recommended and I got used to
actuating the buttons firmly, the effect seems to have disappeared.

Bob,

Look at the "Split Mode with the Sub receiver:" portion of the manual

As typical in split mode, you will transmit on VFO B and receive on VFO A.

Do not fall into the trap of mentally associating VFO A with the main
and VFO B with the sub. It is sometimes that way, but not always -
consider that there is no transmit associated with the subRX, but there
certainly is transmit associated with VFO B when in split.

If using the SubRX in diversity mode, split works the same as a K3
without the sub, but if you are in non-diversity, there is no need for
split - VFO A will be your TX frequency and VFO B will move the subRX to
whatever frequency you want to listen to (the DX station).
