Andy, G4JNT, has produced an interesting writeup of his 500KHz beacon project. This can be found at http://www.g4jnt.com/500kHz_beacon.pdf

A number of us are familiar with the webSDR at University of Twente. This is a multi-user SDR that runs on 80m, 40m and 20m. This has now been expanded to a world wide network. This program is a beta test, but the authors say that when these beta tests are successful, the software will be made available publicly on this site. That is very exciting news indeed.

PS for a short time only one of the receivers is currently set up for 0..20KHz (it was set up for the Christmas Eve SAQ transmission on 17KHz), so if you have ever wondered what it’s like down there, now is a good time to find out.
