I worked several EU near my noise floor (S 0-1) with my radio set to 150 Hz (Icom 756 ProII) and an omni antenna sandwiched I between stateside Ops that were S9 or stronger. Yes, the really close in ones, less than about 400 Hz, add to the challenge, but anyone more than 500 Hz away is a non-issue. I have two stations (at a KW+) about two miles from me in opposite directions and we easily operate within a KHz or each other routinely with no issues. We do see each other on the spectrum scopes, but nothing degrading operation. Maybe we are lucky. 

tnx
