G0KYA's Amateur Radio Blog

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 charts for January 2010

I have been experimenting with HamCap. It uses the VOACap engine to produce propagation maps and charts. As an experiment I have created a series of band-by-hour charts for the UK - now updaetd for January 2010. These are based on 100W to a dipole at 35ft, with a smoothed sunspot number of 17. They are all short path too. You can try them here. I think that 20m looks a bit optimistic with propagation way after sunset - time will tell!

G0KYA's HF Propagation Podcast for November 2009

Will sunspot 1029 still be active when it comes back around the sun later this month? Will 10m open up again for CQWW CW like it did for CQWW SSB in late October? Find out more about this and the best HF bands to use in November in this month's podcast. Use the link above or search for G0KYA on iTunes.
