Adding to my list of “want to build’ items, I saw this one tonight.
OpenBeacon is an open source crystal-controlled QRPp beacon transmitter kit which can output a variety of slow-speed modes, including QRSS, DFCW, and Sequential Multi-tone Hellschreiber.

I was playing around with this WebSDR in Slovenia tonight, well it was around lunch time over there 🙂
The first station I picked up on 40m was a CW beacon “IZ3DVW/B” from Italy, I “googled” the beacon callsign and found out it’s running 100mw into an inverted V dipole.
I’m not completely familiar with the geography so I used an online grid square converter to work out the distance between the SDR and beacon.
Based on grid square to grid square it was 268km, not a bad distance for daytime on 40m from a low powered beacon 🙂
Thanks to the guys in Slovenia for running the WebSDR, it works pretty well and I can’t wait to test it during something like CQ WW!
