What the columns mean:
Spotter = the spotting station
dx = the dx being spotted
spots = the number of spots the spotter made for the dx
total = the total number of spots the spotter made during the contest
pct = percentage of the total spots the spotter made for just that one dx

I took out all the k5d cheerleaders, including one who spotted them 51 times
over the weekend... is there a reward for spotting them on every band/mode
or something??  I also took out several special events, some other WAP thing
spots, and at least one REF contest cheerleader.

Yes, it does look like rx9am spotted himself several times:

The spots appear normal, they are from a regular node (the k1ttt-14 one was
probably delayed and got in the back door first), and there is even one
non-contest one in the mix... which makes it look unlikely to be someone
harrassing him.

Single spotter report

"Single Spotters" are stations who make only one dx spot in the whole
contest weekend.  It is obviously fairly unusual for a contest operator who
is active to make only one spot, many make 10's to 100's of spots during the
weekend.  It is common for DX'ers to make a single spot for a rare dx
station then turn off the radio, so lots of single spotters for rare
stations is common, but they also get lots of contest spots from other
stations.  The key here is the percentage of spots that are from 'single
spotters'.  A high percentage can be a sign of the use of fake callsigns to
spot yourself or a friend that you don't want to look like you are
cheerleading for... in any case, the use of fake callsigns is an obvious
sign of someone trying to deceive the world in one way or another.

What the columns mean:
DX - the dx station being spotted
Total - the total spots for them in the weekend
All(%) - the total number of single spots and the percentage of the total
dxs(%) - the number of the total spots that came from dxsummit and the
percentage of the total they are.  These are broken out because it is very
easy for someone to put in fake callsigns on dxsummit and it has been a
common source of abuse of the system.

LA/OE9ICI       23      10(43%) 3(13%)
UE1QFF  73      10(13%) 3(4%)

That looks pretty much 'normal' to me.


Ok, this is a resurrection of an old analysis i did on ip addresses from
dxsummit.  I haven't done this properly in a while because the dxsummit web
site was undergoing renovation.

undisguised self spotting by 2 stations from one ip may be a new one for
this report.
