Flex-3000 Strange RX Behaviour on 75 meters.

Steven Hess

While trying to operate on 75 meters my RX sensitivity seem to be dropping off. 
The noise floor will start out about S-7 (this is the normal noise floor here) and drop to S-3 over a period of time with a resulting loss of sensitivity. Is not happening on 20 meters the only other band I've been running recently. Doesn't seem dependent on where I set the AGC-T (normally I run it at 60)

Running PowerSDR v2.7.2  on a 6 way AMD locked to 3.0 GHz with 8 gigs of RAM.
