Aurora

On January 21, 2010, in Amateur Radio, by TF4M

We have Aurora now and things do not bode well for the CQ WW 160m contest coming up.

I found this beautiful Aurora photo taken in Reykjavik by Fredrik Holm last night on the web.    Click on the photo to enter his beautiful Aurora photo gallery.

I hope to have my own Aurora photo gallery soon.

More photos from the Aurora last night.

Glorious Aurora photos  may be viewed here.

I can´t resist linking to one of the most beautiful Aurora photo I have seen.   LalliSig is the photographer.  You may click on the photo to enter his site.

Bad times ahead

On January 20, 2010, in Amateur Radio, by TF4M

Solar cycle 24 has begun.

The first radio blackouts are already occurring following a recent solar flare – the first in the new solar cycle….Sadly, this may spell the end of the glorious conditions experienced on 160 meters.

These kind of conditions may never repeat themselves in my life time.

A solar flare may cause enhanced conditions for stations outside the Auroral Zone.   For stations in Iceland, a solar flare invariably causes exteme attenuation of signals.

Iceland is affected by Auroral conditions approximately 250 days a year.    In comparison, England is affected by Aurora 5 days a year.

The attenuation by the Aurora varies from band to band,  160 meters are most seriously affected and the attenuation  can be in the neighborhood of 130 dB.

This corresponds to a power factor of 10 billion times.   Obviously, increasing power is not an option.

This is why I ask my visitors bring a bottle of something nice.   So, in case we have Aurora, we can watch the Aurora in the sky and drink from the bottle.

Since 160 meters are effectively dead today, I printed out QSL cards for all new band/mode contacts made in 2009 – approximately 4,000 QSOs.

The card stock will be cut next time I go to Reykjavik and delivered to the TF Bureau.

CQ WW 160 – TF4X

On January 17, 2010, in Amateur Radio, by TF4M

Siggi, TF3CW was going to activate TF4X in the CQ WW 160 meter contest, but unforeseen circumstances caused him to cancel.

Yuri, K3BU,  has stepped in and will operate the station in  the  Single Operator High Power category.

I sincerely hope that there will be no sun spots and no Aurora.

This may be the last chance in our life time to enjoy these fantastic conditions on Top Band.

I also hope the activity will reflect this – it would be so very cool if Yuri was able to work All 40 Zones in the contest !

It is interesting to note that I have followed the Tesla Radio Club project for years and several times I have been on the verge of writing to Yuri to invite him to my station !
