RBNHole is software that compares spots logged on the Reverse Beacon Network (RBN) with alerts posted on sotawatch. Provided there is a match that meets certain criteria, RBNHole posts a spot on Sotawatch to indicate that callsign X has actually been heard calling CQ on frequency X.
There are ways of labelling your alerts to change some of the parameters, from time tolerances to forbidding RBNHole from posting any spots for you.
If you posted an alert for a cw activation and your CQ is “heard” by a RBN monitor (which all run a skimmer system using licenced software) then your CQ will be automatically spotted, so even if you have no internet access and nobody has answered your CQ yet, you could be spotted on SOTAWATCH automatically by this system.
RBNHole was written by Andrew Ryan VK3ARR and is based on the concepts of the RBNgate system originally written by Eric June KU6J (SK).
Hope I’ve got all the details correct. Apologies if not. Andrew is in South Korea and will probably respond when he has time.
