The QRM is Back!

After almost 30 years spent working in Germany, Belgium and Switzerland (HB9DRV) I'm now back in the UK living in North Helford, Cornwall. As I get a station assembled I'm writing the software I want, and of course it's free to anyone else who wants to try it.

So dig in - as time marches on this collection of small programs will grow but will never become as complicated as Ham Radio Deluxe or, instead it's really just simple software by a very simple programmer.


Simon' Toolbox (Free)

This is a simple Windows program which displays Greyline, Geomagnetic Indices, Solar Data and Sunrise & Sunset.
