[UK-CONTEST] WPX GW9T First Time Out

[G3SJJ]

Fantastic reports from both of you. Keep at it.

Callum, you want to get hold of ON4UN's Low Band DXing book. It has lots of
very useful info. Also, have you got EZNEC antenna modelling software? You
can try various feed points, lengths, heights etc and see the effect.

Adrian, your 40m loop was fed for high angle so you would expect good Eu
propagation, maybe that's what you were aiming for. I think I would have
made it for 80m and fed it ON4UN style for low angle and then a dipole for
Eu.

I've been using a pair of phased 1/4 wave verticals here for 40m over the
last 2 years. Very simple mechanically, the tubing was salvaged from 2 old
Butternuts and a broken A4S. Just need to get the lengths of the phasing
lines correct, plus say 20 radials. About 1 s-point difference East to West
on close-in Eu but 4 or more s-points on DX. Very weird in the evening to
hear VK then switch to West and hear Carib on the same freq.

Hi Callum

The Delta Loop was a full wave Loop, triangular in configuration. Fed at the
middle of the Horizontal base section. We fed it with a Quarter wave of 75
Ohm Coax (note the velocity factor comes into play here) then onto RG213.
The Horizontal Section was about 33 Feet off the ground.....

We had it running N-East - S-West. Yes we worked a fair few VE's and W's on
it, in fact I worked a VE7 who was mobile ...weak but there.

We have received reports that we hit 5/9 + 60 into Amsterdam, with plenty of
DL's / DK's saying we were the loudest signal on the band. Certainly we
where heard in Ipswich at 5/9 + 30.

Our next effort will be to build a 7MHz Quad (from wire) firing to S
America...just for the hell of it !

Incidentially we can get our masts up to 135 Feet, as long as we have 5
people to help. But like most clubs, general apathy has set in, with a hard
core of 2 or 3 to go out and do this. As I said, volunteers welcome !

What a great story Adrian.

The Delta loop: Did you feed this with coax and a 4:1 balun? Where did you
feed it - In the middle? At the top? Can you elaborate for me?

How did you find it performed for DX to the USA. Did you mount it North-East
/ South-West?

Too many questions, I know! Sorry.

Hi all
we aired our new contest call for the first time last weekend, as GW9T
(Wrexham ARS aka Barking Mad Contest Group the Barking Mad bit came from a
club member who suggested that we are Barking Mad to go out and play in
contests in the middle of winter ! But hey, why not !).

     Total      1578       659   1975682

It was our first time out in WPX, although we did operate in CQWW SSB, and
SSB Field day last year. The station was operated by Steve (MW1STE) and
myself (M1LCR). We operated for a total of 41 Hours. We ended up changing
our 160,80 and 40M aerials as we had considerable difficulty loading them (I
flashed a Palstar 1500CV ATU at 2am !).

Anyway, we had a lot of fun, and learnt a lot about aerials and contesting.
(Incidentally we operate Field Day style, as none of us have sufficient
garden space for anything decent below 14MHz. So last Thursday and Friday
Steve (MW1STE) and myself, ably assisted by James (M3JRP) erected two 72
Foot masts, two 35 Foot masts and a mobile tower. We ended up as follows:

10-15-20 Cushcraft A3S on Mobile Tower
40 Delta Loop at 72 Foot (Apex) / Quarter Wave Vertical
80 Quarter wave Vertical
160m Dipole at 72 foot dropping to 35 Foot.

Icom 756PROII + Dentron ML2500 Linear +Daiwa Auto ATU / Palstar 1500, all
powered from a Honda 6.5KVa Diesel Generator.

The whole lot coming down on Monday morning. I am now barred from using the
family caravan for contesting, due to the significant amount of mud trooped
into the thing, during the contest. So we're off to buy an old caravan to
convert to our contest shack. We operate from a disused airfield, 10 Miles
South East of Wrexham, with a reasonable 360 Degree take off.

As you can gather we are beginners at this sort of thing, so any advice
would be welcome ! As would any volunteers to join us !

Adrian (M1LCR)

PS, Don (G3XTT) if you read this it was me who was the cheeky sod who said
"Evening Don" when we worked you on 7MHz ! Steve worked you earlier on 3.5,
but is a bit quieter than me !
