In the first full episode of Zone Zero, Bud looks at the SP DX RTTY and BARTG 75 RTTY contests.
Both events include a continent multiplier, which adds a fun extra dimension as you scour the bands trying to find all six continents – Africa, Europe, Asia, Oceania, North and South America.
If you’re new to the podcast, let me point you to our introductory episode – which I’ve called Episode Zero – as it is a bit of an introduction with info about me and why I started Zone Zero. It’s a good primer for anyone wondering what this is all about.
I want to say a few words out of the gate about location. I am on the West Coast – in the gorgeous southern interior of British Columbia.
To give you an idea of the geographic location, we’re about 60 miles north of the Washington State border. Spokane, Washington, is about 260 miles driving distance to the southeast of us. And Vancouver, BC, is about 240 miles to the west.
Our location on the west side of North America means something to fellow hams from California all the way up to Alaska, as we combat the aurora borealis and its impact on the frequency bands we know and love.
The further east you go, the less you have to rely on the polar path to reach Europe, and the aurora has less impact. From my corner of the world, at least, I have to point directly through the heart of the auroral zone if I want to hear — or be heard in — Europe.
Auroral oval — a donut over the pole
So, imagine the aurora as a great big donut or bagel shape, suspended over the north pole. That donut gets bigger or smaller, depending on geomagnetic conditions – when the sun is storming — spewing a coronal mass ejection or high-speed solar wind at Earth — the aurora gets stronger and bigger, essentially absorbing radio signals so they simply do not pass through.
In this part of the world, if we want to reach Europe, our signals have to go through the near side of the donut, over the polar ice cap, then through the other side of the donut into Europe.
With strong auroral conditions, very little signal gets through – if any.
Now, sometimes, the donut pushes so far south that parts of Northern Europe are actually inside the oval. When that happens, we might see a curious phenomenon known as the Scandinavian Express.
If I point due north even when the aurora numbers are elevated, I can quite often work Scandinavian stations in Sweden and Norway, when I can’t hear anything else at all from Europe. That can add a few multipliers to the log when nobody else is hearing me over the pole – it’s worth a listen even on days of poor propagation.
It’s tough from the west coast, going through both sides of the auroral oval – it is a significant factor in contesting in northern latitudes, and in particular from the west coast of North America because there’s no other option for working Europe. Keep in mind that pointing long-path to Europe means going through the aurora Australis, which is usually just as strong over the south pole.
Over the past weekend, in the YU DX contest – where Yugoslavian stations were the focus from around the world – and in the Manchester Miniera CQMM DX contest sponsored by Brazilian hams – conditions were quite bleak, but we did make some contacts over the pole on 20M or 14 Mhz, and I even made two contacts in Europe on 40M, which from this part of the world can be a challenge during low-sunspot years.
So conditions were bad but not as bad as I expected.
Let’s take a look ahead at the upcoming weekend contests.
