Let's say we are tuned and listening to a USB transmission, and there is
another USB transmission 1-2 kc lower on the band, such that the two
transmissions overlap. Other than sliding or shrinking the passband, turning
off preamp or lowering AGC gain to try to reduce the QRM to noise level,

If they are coming from different directions, then you can use the second
receiver
as in Flex-5000 option (on a separate antenna) to create spacial diversity,
or even
rotate a directional notch onto the interferer. These directional notches
are quite
narrow in angle, but can be many tens
If the interfering signal is on a different azimuth, it is possible
the diversity features already in beta PSDR would help if you have
the 5000 with rx2 and a diversity antenna. w9oy has written up some
of his experiences on his blog.
