[K3] clarification on VFO and 2nd Rx

Barry N1EU
I'm unclear about VFOA/B functionality when using the main and
subreceiver in diversity mode (i.e., tuned to same frequency) and the
transmitter in split mode.  It seems that the subrx needs to be
assigned to VFOA in this case but I'm not sure if the K3 provides that
flexibility (like the Orion).  The manual attempts to address this
specific case as follows, although I'm not getting it:

"Split Mode with the Sub receiver: When operating split, VFO A is the
receive frequency and VFO B the transmit frequency. If the sub
receiver is on, you'll be able to listen to both your receive and
transmit frequencies in receive mode. Hold SPLIT to turn split mode on
or off."

Can someone explain what the manual is trying to say here and how
VFOA/B is being assigned to the subrx in diversity/split?  Is the
subrx always assigned to VFOB or is there more flexibility than this?

Thanks & 73,
Barry N1EU

You might have seen my post asking for clarification too. I'm pretty sure
KRX3 will always use VFOb and can not be switched at present.
My understanding is that with the sub on, its audio goes to the right
channel of the stereo output and VFOa's audio goes to the left channel.
That's regardless of SPLIT or not.
So in a pile-up, you can here both the freq when the op is working split.
In other situations, you might be calling on a fixed freq and listening for
CQs on other freq.


Forgive me if I've got this wrong, as I said, I mailed for clarification
too.

To accommodate diversity reception, the K3 needs to be able to assign
different frequencies to the subreceiver and transmitter.  Sure, audio
from the two receivers can be tied down to separate L/R outputs.  But
it seems that the subreceiver needs to be assignable to vfoA OR vfoB.
I don't believe you could change vfoB frequency "on the fly" to swap
receive/transmit frequencies in diversity split because of settling
time and needs for fast qsk.
