Hello,
this is of interest for ham radio amateurs. I had nothing to do and was looking at the Reverse Beacon Network to find some new contacts. That's when I had the idea of redirecting the DX-spots to my Arduino. The Arduino is connected to a telnet server and the messages are interpreted and displayed on a RGB Shield. It is nothing special but may help to find some new interesting contacts via CW and the Reverse Beacon Network is really fast and so is my Arduino.
Details as usual on my blog: http://hajos-kontrapunkte.blogspot.de/2013/04/arduino-as-reversebeaconnetwork-client.html
Stay tuned!
