Caros,
O K1TTT divulgou novamente a análise dos spots durante o CQWW CW. O
objetivo desse trabalho do K1TTT é identificar possíveis abusos no uso
da rede de DXCluster, como auto-anúncio ou anúncios com origem
camuflada.
Uma forte indicação do forte impacto da Rede de Beacon Reverso é que
56 mil anúncios gerados pela rede de cluster tradicional não se
comparam aos 1,7 milhão de spots gerados pela RBR no ultimo fim de
semana.
Outro fator enviesado do DXCluster é quanto mais rara a estação é, mas
spots recebe, vejam o caso de ZL8X que recebeu 1210spots no CQWW CW.
Mesmo nesta era da informação que estamos vivendo, é assustador a
quantidade de informação gerada pela RBR. O DXCluster cairá em desuso
em pouco tempo, pelo menos durante as competições em CW.
Abaixo o relatório do K1TTTT...

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.

ok4pa.

Single spotter report
This is the count and percentage of all the spots for the dx station that
were made by a call that made only that one spot for the whole contest.
Note
I left in a couple of non-contest special events, they normally have higher
percentages since they get spotted by dxers who may just spot them and turn
off the radio. Note the percentages for them are 15-20% or so, which is
about normal.
DX Total All(%) DXSummit
ZL8X 1210 204(16%) 70(5%)
C5A 653 36(5%) 12(1%)
PJ5/SP6IXF 174 35(20%) 11(6%) (non-contest)
4L5O 63 25(39%) 25(39%)
ZD9T 69 25(36%) 12(17%) (non-contest)
VK5AUQ 70 18(25%) 4(5%) (non-contest)
IK6CWQ 25 17(68%) 2(8%) (non-contest)
9L5VT 378 17(4%) 7(1%)
ZK2A 182 17(9%) 9(4%) (mostly non-contest)
UT0AZA 48 16(33%) 16(33%)
PJ2T 444 15(3%) 6(1%)
Consider ZL8X as the baseline.. Out of 1200 spots for them there were 204
spotters who spotted them once and turned off their radios for the
weekend... of those about 1/3 made those spots from dxsummit. That is what
i would consider 'normal' for a relatively rare dx station. C5A wasn't too
far behind. The PJ5/SP6IXF, ZD9T, VK5AUQ operations were not in the contest
but kind of hit the same ranges.
This kind of makes 4l50 and ut0aza stand out in the crowd with high
percentages, all of which came from dxsummit.
