Update 06 December, 2011:
The SAC Contest Committee, in their wisdom, have refused to acknowledge the fact that TF4X had the top score in Scandinavia in the category and only marked the certificate as 1st Place – Iceland…
All attempts at diplomacy failed, although the Contest Committee became divided over the issue.
I have therefore marked the Certificate accordingly myself. A simple and elegant solution.
It is a little known fact that TF4M/TF4X and socially mature TF stations have since 2009 boycotted the SAC to bring pressure onto the Contest Committe in this matter.
If you have wondered about the absense of the top TF stations, this is the explanation.
It has now become crystal clear that the top TF stations will never again take part in the Scandinavian Activity Contest.
It is easy to win a contest, when the competition is absent.

Yngvi, TF3Y operated TF4X in the 51st Scandinavian Activity Contest on CW over the weekend.
The day before the contest, he made around 800 contacts to get acquainted with the new shack.
The score is higher than last year´s winning score in the Single Operator – 20M category.

At this point it looks like TF4X has the highest score in this category – this may of course change as scores get submitted…
UPDATE: The results have been published and TF4X is the winner of this category!

I made some recordings of the contest with my Beverage antenna system and the PERSEUS SDR.
You may download a file (147 MB) of the last few minutes of the contest spectrum on 20M CW and play back the spectrum using WinRad on your own computer.
In order for WinRad to be able to play back recordings made by the PERSEUS software, you will have to download the PERSEUS DLL for WinRad and extract the files to the WinRad directory.
If there is demand, I can provide larger files of the last hour of so on 20M during the contest.
The station performed as expected, except we discovered, when I operated TF4M on 80M, that the 80M antenna is located too close to the JA rhombic, causing 80M operation to trip the protection circuits on the amplifier on the 20M station.
I operated TF4M on 80M for 45 minutes out of the 24 hours and made 50 contacts.
Without bandpass filters in place, this discovery would have followed the total destruction of the 20M transceiver. As it were, there was no damage, although the JA rhombic was picking up 50W or so from the 80M antenna….
The first indication of a problem was that I could hear faint noise coming from the 20M operation when listening on the TX antenna – there was no trace of any noise using the Beverage system.
I cascaded two sets of bandpass filters on both 80M and 20M stations, but I could still hear faint interference and then we noticed the faulting of the 20M amplifier when the station was switched to the JA rhombic.
I will solve the problem by relocating the 80M transmit antenna.
