I used it a lot this weekend to keep out those pesky adjacent channel RTTY
contesters! Only once did I use it for CW and he was doing the jamming
thing...
BTW, some fool was trying to chase RTTY contesters out of the 14070 to 14074
area. What's that all about? PSK window? I had to laugh when after several
attempts at jamming me, he came up doing the hunt and peck on RTTY at
14072.5 to tell me I shouldn't be on RTTY between 70 and 74! Hi! ...and of
course there was never a callsign used...

If the CW signal is not much louder and don't have a lot of
keyclicks, you can usually copy an RTTY signal through an adjacent CW
QRM even when it touches one of the FSK tones.
Unless there are two separate CW QRM signals riding *both* of the FSK
tones, you can copy RTTY that is strong enough by using Mark-Only or
Space-Only copy.
Mark-only and Space-only also works well with two RTTY stations that
are overlapping each other, as long as one of them is not overly
strong as to get their keying sidebands to interfere with the "clear"
tone of the RTTY signal that you are trying to pick up.
