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.

Propagation predictions for International Marconi Day
Right: Peter (M0RYB) hard at work on the key at GB0CMS last year.
International Marconi Day will be held on Saturday 30 April 2011 this year. I help to run GB0CMS at Caister Lifeboat in Norfolk and thought it would be a good idea to have some idea of propagation conditions to the other IMD stations around the world.
I have therefore created some charts that show the reliability of paths to Italy, East Coast of USA, West Coast USA, Iceland, Newfoundland and Uruguay - the locations of the majority of the IMD stations. These should help you get your award.

For info, they were created using HamCap (a VOACAP-based program) using a smoothed sunspot number of 41 and based on 100W CW to a dipole at 35ft. Scale your results accordingly.
