There has been some discussion about this on the NASOTA group and the beta version is now online.
Eric KU6J is running a reverse beacon network gateway for SOTA stations. RBN is a system using a piece of software called a CW skimmer. Depending on the radio this monitors part of the CW band or all of the CW bands and decodes CW stations heard. You get a callsign and signal strength. The reports are then posted on the net. There are web sites were you can see real time decodes of who is on the CW bands.
Eric’s extension is to check to see which stations have been heard sending CQ SOTA and grab the frequency and call from the RBN. Now the magic bit… if the station heard on RBN has posted and activation alert and the alert time is within 2hrs of decode time, then Eric’s system will automatically spot the station. There is a lot of code in the system that tries to minimise spurious spots.
So if you post an alert and call CQ SOTA on the key then if you are heard by the RBN you will be automatically spotted onto SOTAwatch. Something which is really rather useful I think.
It’s still beta and you can see some RBN spots currently on SOTAwatch posted under Eric’s call KU6J.
