Don't know if it's a related problem, but when I first started using RTTY it
was with AFSK. I would setup MMTTY so that the mark/space tones were within a
reasonable place in the receiver passband, which was never at 2295/2125.
Which meant that if I had spotted a station, the spot frequency would never be
the "real" carrier +/- 2295 or whatever the math is.
As a result, I avoided spotting RTTY DX until I set up for FSK.

Thanks to Jim, AD1C, on what command to send to the cluster so I can see what
was spotted around the frequency I was on. All I found though was one other
legitimate call 2 Khz up. So I'm really at a loss why during those 15 mins of
calling CQ I had multiple ops already logged call me again. No other time
during the entire contest did I have a single station call me that was logged
as a dup. I guess the mystery continues unless someone has another idea.
And thanks again to AD1C for the info on how to check. In case others are
interested the command was:
SH/DX/99 3579-3581
73,
David
