You cannot DX on 10 metres!

That is the "advice" given to me by older "wiser" UK Radio Amateurs. It's all ground-wave - no good for DX during a sun-spot minimum, they say. At a local Amateur Radio club, the members turned their nose-up at a suggestion of a local 10 metre net. "It will not work, people are too far apart, better off to use VHF", they complained. And therein seems to lie a pathological dismissal, and almost hatred, of 28MHz in the UK. WSPR has proven them very, very, wrong!

My work colleague, Andy G6UQZ, and I are having a bit of a WSPR competition. He is using a magnetic-loop and boasting of it being steerable - and catching VY0ERC (Hello Canada!) at the top of the world. I was using my doublet-dipole on 160, 80, 60, 40, 30, and 20 metres, and was very pleased to see spots all the way to Australia and Tasmania (G'day). "Ah", said Andy, "but you are not getting spots from there or there!" - pointing to other parts of the map. Challenge accepted! Whilst I cannot steer my dipole, I can switch to my Solarcon Imax 2000 vertical. It is a Citizens' Band aerial, and was put up for that purpose. Sold as a 5/8-th wave, it appears to be a 0.64-wave internally - at least that is the opinion of the mad-guy who took a Dremel to one to open it up! It works perfectly from 20 metres up to 10 metres, and only needs a matcher on the lower frequencies. The WSPR results have been amazing: East Anglia to Scotland spots confusing the received wisdom of ground-wave and skip-zone; East Anglia to Belgium and The Netherlands also confusing the skip-zone theory; 28MHz spots running over 1500km away defying the received wisdom you cannot DX on 10 metres during a solar minimum! The omni-directional nature of the vertical has also seen spots coming in from as far away as Brazil and northern Canada.

So when people tell you that you cannot DX on 10 metres. Laugh and point them to WSPR!
