Leroy,
I believe the "change" you request is already available, it just takes
some understanding of the difference between Diversity mode and the
subRX in non-diversity.
When the K3/K3S is in diversity mode, the operation is just like a
single receiver - both the main and subRX work from VFO A, except that
you hear the subRX in one ear and the main in the other.
If you have antennas that are compatible with diversity receive (such as
one vertical one the other horizontally polarized), then you will have
full diversity when you select the AUX antenna for the subRX.
So, when you select DIV, both receivers will be listening to the same
frequency - that is already the norm.
Much of what you request can be answered by a study of the antenna
configuration diagrams in the manual. I believe what you want to
achieve is already present.
If instead you meant "operating frequency" to mean your transmit
frequency in split mode, then you do not want diversity receive, you
want the SUB turned on in normal mode. The subRX will listen to the
frequency on VFO B (monitoring the pileup in most cases). When you go to
SPLIT, the subRX will listen to your proposed transmit frequency on VFO
B the main RX will listen to the DX on VFO A.
With the subRX installed, you have an option of not going into split at
all, set VFO B to the DX station, and tune the pileup with VFO A.
Transmit will be on the VFO A frequency (without SPLIT).
I hope this clarifies the situation for you.

All of the RADAR and beacon systems I worked on before I retired from the

used diversity receive. I could see the video clean itself up , but it was a

I did not expect the diversity receive to work excellent like it does on my
K3S.
I was a little hesitant to get the SUB receiver, I was not sure the advantage
was worth it.
What a mistake that would have been!
Here is a firmware request for the DIV button:
Could it auto tune the Subreceiver to your operating frequency when you turn
on the Diversity ?
That would be so cool. It might already be able to do that, I just have not
discovered it yet.
