Bill: If I had to take a guess, I would be looking at the roofing filters. 
They are in the RX chain, but after the point where the sweep takes its 
signal.  Everything appears to be fine up to that point.  Check over the 
entire range of bandwidths to see if it's a single filter.  If it's bad at 
all bandwidths, then the problem could be in the A5 board, perhaps FL5 or 
FL1 or any circuits associated with them.  It could also be in the A7 logic 
board, but I would tend to discount that if the transmit works OK.
