For those who want to dive into busting world, it very easy to collect RBN data available here http://www.reversebeacon.net/raw_data/ and list variations of correct calls aroud a frequency. For examp

Steve N2IC asks a very pertinent and interesting question? "How seeing 200+ unidentified panadapter blips on a crowded band helps you to identify non-duplicates and multiplier stations when you are r
Hi Kevin There is a way to solve your specific problem. I call it the simple rotary A/B switch solution! But you need a dedicated SO2R station. When you say "I would like to have the hardware used fo
The purpose of this post is to present a way to implement a dynamic error free Skimmer-RBN/Packet network that automatically: 1. Flags and eliminates Busted Spots from the network 2. Flags and elimin

I received several e-mails regarding the understanding of the dynamic error free RBN. In order to explain this graphically I will use the DR1A case from CQWW CW 2012 on 40 meters. DR1A was the most s
Hi Rudy My analysis is NOT based on stations that generate a lot of spots! My analysis, started from two basic observations: 1. Problems with Busted spots; Non-existent spots on a particular frequenc
I think a clarification is needed regarding the so called CT1BOH error free RBN algorithm In order to do that let me first put all relevant "boxes" in this contest eco-system: 1. Contest signals on t

It is amazing to me, how some people jump to conclusions without deep diving into the data. Some just look at some log lines and feel free to say whatever, as if that alone would mean anything at all
Stan and Kelly Don't take me wrong, but I'm not going to elaborate more on TO7A log. I was not involved in the checking of this log, I did not see the material presented by the log checker(s), and as
Dmitry As I have said I don't want to go on "live" log-checking. My posts had one intention, to explain to all, that looking at log lines alone will tells us nothing. Log checking is complex, and the
