Hi Bob,
<<<
After the contest I searched for my call on DX Summit to see who spotted
me and noticed that almost no one did besides myself.
>>>
Based on dxheat.com database, you've been spotted 114 times (without your
selfspots) during the ARRL DX phone 2023. Not too bad for somebody that
"almost no one did beside myself"...
That said, here is my experience about selfspots the last weekend (part time
activity - 6 hours). All my selfspots only generated a few calls (almost always
the same operators when changing bands), then the flow of calls was nothing
like that generated by a spot on the cluster. But when a North American station
put me on the cluster, it was really different and I found myself with a
continuous stream of callers. I therefore deduced, like De said, that most of
the participants filter the origin of the spots (something that I never do and
many could be surprised by what we can contact even if the spot comes from
another continent !).
I don't think that selfspots are counter productive since I've been spotted 48
times by others for 05h56 on air which seems to me a normal spot rate.
