One more interesting thing is the number of different K3LR "like" busted
RBN
spots (such as EK3LR) that show up in the logs of single operator
unassisted
entrants. How does that happen?
It's the fault of skimmers. According to the "Cupel" theory, the busted call
transmutates in the skimmer and creates interferons which synchronize with
the CQ speed of the run station and are retransmitted, unaffected by normal
filters, causing pseudo-standing waves (on rare occasions reclining waves
have also been reported) in the audio output of the receiving radio. The
result is for example a "dit" in front of a call sign with a "3" following
the "K" and a "dah" in front of a call sign with a "5" following the "K" as
in EK3LR and TK5GO. Unfortunately, the interferons are crafty little buggers
and only sneak in to the radios of unassisted contesters who swear-to-god
have their packet window closed and then quickly disappear. This seldom
occurs with call signs having a two-letter prefix and apparently has not
shown up in logs of stations working, for example, NY4A. However it is
possible the 2x1 call signs are retransmitted intact and therefore the Cupel
effect cannot be easily recognized or measured.
Investigating this phenomenon would be a worthy application for a multi-year
Ph.D. research grant from one of the major universities and funded with
taxpayer dollars.
Hope this answers the question.

Interesting that because the callsign EE5E was getting put on the known
"bad
list" by many contest stations - as a frequent busted Skimmer post - EE5E
is
no longer using that call.
It is also interesting how many guys work EK3LR and then log zone 21 (did
they really listen to the callsign or the exchange on the air?) - in the
CQWW CW contest. The K3LR CQWW log checking report shows all of the
"renditions" of K3LR that were in other logs. Some are far out and
fascinating.
At least the K3LR Skimmers do not send out EK3LR to the RBN (we trap about
200 bad callsigns that the K3LR Skimmer thinks it heard, but we know are
bad
- including EE5E). We add more "renditions" as we discover them, but we
have
to be careful, because EE5E "was" good for many years.

Seems to me that a published black list should be made and used to filter
out bad spots before they ever get to everyone's computer. EK3LR, for
example, should not show up on anyone's screen.
On a secondary note, what causes there to be a huge number of EK3LR spots
from all over the world and not a single EK5GO? I sure would hate to be
in
Armenia and have been assigned EK3LR. Yikes.

I don't know what software you were using, but speaking for N1MM Logger,
there are a number of ways to deal with this problem. In the bandmap or
available window, you can right-click and select "Blacklist Callsign". Not
only will this remove the callsign from your computer, but also every
computer in the network. You can also set up and import a blacklisted
calls
file before the contest containing the most common busts, like EK3LR.

Wow! I wish NY4A could have found wherever it was you were getting your
spots. We filtered out dozens of busted calls and skimmer perversions
like "EK3LR", dropped leading letters, "O" for "Q" and the phenomenon
reported where the spot was for, or on top of the mult, picking up the
calling station as the runner, etc. And like "Whack-A-Mole" we'd delete
them from the band map and a little while later the same busts were back
again. All pretty annoying as M/2 trying to work them quickly and get
back to the run frequency without losing it.
Having said that, seeing the "instant spots" from all over coming up
instead of having to wait for someone to manually post the spot made a
big positive difference. I noticed it when we went to a new band or had
to change frequency.

Are we talking about the same contest, Bob? No reason that the
Russians would be working 9H1s.
Actually, I'm more interested in the busted calls you reported. It's
not that busts don't happen, because they do, but because
readily-available filtering can catch almost all of them. I was only
on for 10 hours and 1000 contacts, but they were almost all S&P. I
worked out 3 or 4 bands at a time - 0 spots waiting to be worked - and
in that time I saw exactly 1 bust that made it through to me.

Probably not anyone cheating in the manner you describe.
I found this a LOT. (Among all the other busted calls).

It seems like a couple of Russian station are cheating using the
cluster.
I operated AB unlimited over the weekend and was checking spots the
whole
weekend.
As the contest progressed over the weekend semi rare mults were worth
QSYing to. Over a dozen times as soon as the call appeared on my
band map
I
QSYed to it only to UT0U merrily CQing away. (There I named a call!)
Another U station did the same thing but I forgot to get his call.
The
calls
spotted were semi-rare mults like (9H1 etc), but rare enough to
attract a
crowd. Once would be a coincidence, but it happened many times. Every
time
there was no hint of the station spotted. Pure out and out cheating!
Did anyone else see that behavior? The only way to stop this crap is
to
put pressure on them.
