Vince, I don't know exactly how to answer your question, but here's a
very simple thing I've done that really enhanced my split operation.

I enter split via the following macro:
SWT13;SWT13;FT1;UPB5;RT0;XT0;BW$0210;

Note the last command, BW$0210; This sets the bandwidth on the
sub-receiver to 2.1 khz.

For me, this improves split operation considerably. It brings in a
whole bunch of signals in the pileup, so you can much more quickly
home in on the guy who's working the DX. In conjunction with a
panadaptor, this makes it easy to navigate the pile. Moreover, it
brings up the sub-rx audio, and gives it a tone that distinguishes it
from the sound of the DX that you're hearing in the left ear through a
tight filter.

I had the same impression that you have, that the sub-rx had kinda
weak audio out, but this trick made me completely happy. Maybe it'll
work for you.
