[RTTY] Spotting question

[Al Kozakiewicz]

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

But my question is if there is a way to see what might have been spotted between 22:44 and 23:02 Sunday around the frequency of 3580 +/- 1? Any trick on DXSummit or another site to try and find out? DXWatch also allows searching, but again only by callsign for what I can find. Any suggestions?
