With the news that the Russian DX Contest will want additional
information from QRP and LP entrants so that a comparison between
signals can be made using the Reverse Beacon Network, I decided to
compare the results for the recent Sprint CW contest. I compared the
top five LP stations in the 3830 results (in order: KU5B, K7BG, N9CK,
N5DO, and N7CW) for February 6 using the Signal Comparison Tool . I
selected the Reverse Beacon from K3LR because it had the most spots on
that day -- 11,011. Nothing dramatic jumped out at me from looking at
the graphs comparing the signals, except for one thing: The number of
times each station was spotted by the Reverse Beacon. Those were
surprising: KU5B was spotted 0 times, K7BG 58 times, N9CK 0 times, N5DO
72 times, and N7CW 63 times.
The leading station and number 3 were never spotted at all!
I thought maybe it was a propagation issue, so I picked a leading
Reverse Beacon from the west coast, WA7LNW, with 6,038 total spots on
that day. The same pattern occurred: KU5B 0 spots, K7BG 46 spots, N9CK
0 spots, N5DO 37 spots, and N7CW 12 spots.
Is this some artifact of the Sprint contest? Is there something in the
way KU5B and N9CK called CQ that led to them not being spotted? And is
there a secret to being spotted more often? How will results like this
effect the ability of the RBN to be an investigative tool?
