[Elecraft] Diversity receive is fantastic

[Don Wilhelm]

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.
