[CQ-Contest] iota spotting report

[K1TTT]

I was asked to do a spotting report for the IOTA contest, so here it is.  If
you want the raw data you can download it from
http://www.k1ttt.net/logs/2009iota_spots.zip starting as soon as i get it
all zipped up.  I am a bit busy this week so I'll keep it short.

There were 13829 spots in the cluster database.

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
station.

"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.

the group above came from an ip 149.254.192.199
address:        T-Mobile UK
                Hatfield Business Park
                Hatfield
                Hertfordshire
which was from a block of only 255 addresses.

The next group came from a different ip: 149.254.200.216
from another block of 255 from the same isp.

EI3JZ		14181	eu124
F0GAA		21246.5	SWL 5/9+20DB

These 2 seem to be ok, they came from the proper countries at least.

MW3SDW	1420500	eu124 ramsey island
The group above came from 2 different ip's in the same block belonging to
O2Online in Berkshire UK.

The first 2 groups make me curious becuase of the same calls showing up in
both groups that had different ip's.  but it will take someone who knows
more about that service to figure out where they really came from.

IP addresses (several of them, must be dialup) came out of Portugal.
