[RTTY] Spotting question

[David Levine]

I ran unassisted without the cluster in this weekends contest. Sunday
between 22:44 and 23:02 I noticed a few stations calling me again on 80m
after I had already worked them on that band. Despite me sending my call at
least 1 additional time to each, they kept sending theirs so I logged them
again. My only guess is that there was a bad spot posted.

I checked DXSummit and searched for my call and there were just 3 from Sat
night:

I checked my log and N2FF posted the correct frequency so I'm guessing
the other two were probably not adjusted properly for their offset.
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?
