K3 Split questions

Is it possible to have A and B VFO's on different modes? (no sub) If so,
what controls the B mode?

How about having the B VFO automagically go to the same band as A, when
entering split ?

Thanks,
Mike NF4L

Re: K3 Split questions

No, you're not the only one.

Some people use off-band split, so auto conformance of TX band to RX would
break that. Since a double press of A>B brings B on band very quickly, it
does not appeal to me as a great step saver. The logging programs set the
split explicity by writing the logger-computed TX frequency directly to the
VFO.

I would test your second question but I have the KRX3 installed. I suspect
(don't know) that a lot of the particulars are kept in KRX3 dsp memory and
so not available for 1 RX operation.

What happens when you hold BSET button with no KRX3?

Hi Mike:

I have a SUB RX so it is possible that my comments below might not fully
apply if you don't have a SUB RX.

VFO A and B can be on separate modes. When you hold the A/B (1) button
you'll see b SET on the top display. From there you can change modes, fiddle
with filters, preamp, NR, etc.. The settings for VFO B can therefore be
totally different than VFO A. Some things that you can't change will say N/A
when you try to change them.

However, if you want to avoid being in a different mode I would suggest
pressing the A-B (3) button twice. The first press copies the frequency from
A to B. The second press forces all of your selections in VFO B to mirror
VFO A. I always do this before going into SPLIT. The annoying scenario I
experienced before I learned to double press was when I was on CW and
pressed split. I reached for my paddle but nothing transmitted. It turned
out that VFO B was in the DATA mode. It took me a minute or two to figure
out what was wrong.

"B SET" (hold the "1" button), then change mode.

Don't know. I usually do a "A>B ALL" (double-tap of "3") before going QSX.

Thanks, Guy -

I'm not sure what you mean by off-band split. I was just wondering if
there was a setting I didn't know about.

I think you mean my first question. Pressing B SET I can set B to a
different mode.Then when I go into split, the B mode blinks above the A
mode, and the pointer to B blinks as well.
I can change bands, and then split isn't available. I didn't mess with
the filters.

Thanks, Michael -

Since I don't have the SUB RX, and B is always the xmit VFO, I'm not
sure why B SET even works, except maybe for modes.

I had the same scenario as you, and it took me longer to figure out! I
dunno how the mode got set differently on B. The double tap is a good tip.
