Cheerleader report:

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

spotter	dx		Spots	Total	Pct
9A1CAZ	9A9T		50	50	100 (vhf/uhf)
S56P		S56P		19	19	100 yes, self spots.
SQ5FLP	SO5A		18	18	100 
HA3MV		HG10P		18	20	90  (vhf contest?)
DN4SB		DG1EA		17	17	100
ON4ORP	OR0A		16	18	88  
K6III		KH7X		16	467	3
UW7RV		UT7UV		14	16	87
SP9BGL	SQ9LOM	14	36	38  (some kind of special event?)
NO2R		XU7ACY	14	14	100
9A3PG		9A1C		14	14	100 (vhf contest?)
F6EXV		F8BBL		14	16	87

F6EXV and ON4ORP were listing needed states in many of his spots... how do
they know?

S56P spots for S56P were mostly commented 'cq arrl contest', so its not like
he wasn't in the contest or was just playing around.  And he even thanked at
least one station for their contact.

I wish all cheerleaders were like K6III, 16 spots for the same station,
especially dx on your doorstep, isn't so bad when you make 467 spots over
the 48 hours!


"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 

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.

There may be more self spotters in the dxsummit excel sheet, look for
the red or yellow highlighted blocks.  But there were so many special
events and other things going on that weekend that some of them are
hard to sort out.
