Thanks for stopping by. This is where I publish a lot of my features and thoughts on HF propagation, antennas and other ham radio topics. I write for a number of radio magazines, including the RSGB's RadCom and ARRL's QST. I am also chairman of the RSGB's Propagation Studies Committee and produce the weekly HF propagation report for GB2RS. When not playing radio I'm a professional journalist specialising in aerospace, science and technology and am also author of four RSGB books.

Ionospheric Sounding and Digisondes
I recently gave a talk to my local club on ionospheric sounders (Digisondes). I will probably give the talk at the RSGB Convention in October 2011 as it seemed well received. While quite a complex subject, I have added some notes to the presentation to try and make it standalone.
The PDF explains what they are, what they show and how to use them. It also has links to free real-time digisonde plots from around the world and an historical database.
You can download the 4.1Mb PDF here.
