G4AXX

IARU HF Championship 2002



Back to Events



13-14th July 2002, Debden Airfield, TL 559 348.

This time we were joined by Steve G0CKP who brought his FT1000 MkV Field and a Titan amplifier.

This was the first time we used the DxCluster. Spots were fed from an internet-connected PC in Saffron Walden over a 4m link. The path to the airfield was 4.5km path, only just line of sight, it worked very well.

Here are the soapbox comments.

The station set up field-day style from Debden Airfield near Saffron Walden, Essex 
(TL 559 348, JO01DX) using a 2.2kVA petrol generator. This was the first time we 
had arranged 4m access to the DxCluster and the first time any of us had used it. 
It certainly helped increase the QSO rate and at times working spots was as fast 
as running. 

The last time we entered this contest was in 2000, when we were the Country and 
Zone 27 winners. Foot & Mouth disease had prevented us entering in 2001, so this 
year we were keen to compare, and improve on, our 2000 log. 

We kicked off on 15m and made a fast start easily exceeding our 2000 rate. 10m was
very poor to start with but started to open up later in the afternoon (about 18:50z). 

We had a lot of RF feedback in the shack and spent time adjusting levels and fitting
ferrite clip-ons on the leads. 

We made the most of the 10m opening until 20:12z on Saturday, which was just as well
because it didn't open again for the rest of the contest. 

Shortly after at 20:35z we left 15m and dropped down to 20m. As the grey-line swung 
over us propagation was amazing, allowing us to work, amongst others, Japan (x4), US,
Panama, India, Thailand, Australia, Argentina and South Korea in just 12 minutes 
between 21:41z and 21:53z! It felt like 20m was wide open, to the whole world at the
same time and everyone was 59+, quite outstanding! 

The limited hours of darkness at this time of year saw us eek out 20m until 23:00z 
then we moved to 40m. This may have cost us short skip European Q's. 

It certainly seemed to all start going wrong at this point. 80m didn't provide much 
of a pool of activity, and 160m was dire. We have pretty decent antennas for 80m and
40m, and we rather expected decent runs to NA using split, but this didn't really 
transpire. We were thankful when 20m started opening again at about 04:00z! 

We're frankly amazed that Tim, M5ACC, managed to accumulate the score he did during
the night! 

On Sunday morning things had slowed down a lot and by 09:00z our Q total was the same
as at that time in 2000. The expected early morning 20m path to JA never materialised,
and we never did hear ZL. The low MUF forced a lot of activity onto 20m and it was 
clear that the new 1.8kHz InRad's were making a huge difference on SSB! 

15m struggled into life late at about 10:00z and that's where we finished. At the 
end we had 42 less QSOs than in 2000 but 8 more zones & 18 more HQ stations giving
a 10.7% increase in score. It sure looks like we can say a fond farewell to the 
highs of cycle 23 - it's been good to us. 

Listening to the quality of the WRTC operators was a pleasure, but we only heard 
37 of the 52 teams. The weather was rather hot during tear-down and we got sunburnt. 

Our hats are off to M5ZAP & M0TTT for an even better performance this year, well done!
