Hi Rich ...

Thanks for the response.

Actually, I think I didn't explain myself well enough in my posting.  I
wasn't referring to a "DX split" situation where the xmit and rx freq are
substantially different.  I was referring to contest operation where I am
running stations that are normally on my transmit freq but with the
occasional need to fine tune the calling station if they are off frequency.
Rather than do this with RIT, I am accustomed to using SPLIT, fixing my xmit
freq on VFO B and fine tuning for rx with VFO A.  This is what I did before
installing the subRX.

Now that I have the subRX, I want to do the same thing, except put the subRX
in "diversity" mode so that I can listen with two antennas simultaneously
while still reserving VFO B for the fixed xmit freq.  This way I can listen
at the same time to my Xmit antenna and an antenna connected to the SubRX
Aux IN (usually my K9AY).  These antennas have different noise levels,
polarization and directionality, so it is useful to listen with both of
them, at least until I find the station I want to respond to.

My question revolves around how the "balance" control operates when set up
as above.  Some posters have indicated that it doesn't work when in
"diversity" mode.  I'm interested in what others have found useful when
using this type of arrangement.  i.e. - how to quickly emphasize one antenna
or the other if needed for a particular station.
