World Travellers

Hi Bob,

As an update, Team World Travellers are now all home or on their last journey legs apart from Team sub Richard G3RWL/8P6DR who is staying in 8P6 for a while longer as he originally planned.

I think we have all had to alter our travel arrangements to get out of locations before borders or airports close on us, but Iain G4SGX/V31GX has had the most harrowing journey involving a route via two other countries. I will let him describe better in his own words.

73, Colin G4CWH again.

Hello Bob,

I want to let you know how much I enjoyed the Commonwealth Contest again this year.  Conditions didn’t seem to be very good but in spite of that I got more contacts (70) than I have been able to make previously.  Making contacts from here in the Yukon can be difficult – partly due to equipment and antenna (and operator too, I’m sure) but it’s also a long way from most of the centres of activity and I think that people with beam antennas don’t aim this way too often.VY1KX shack
All my contacts were on three bands, 80, 40 and 20 metres.  I didn’t hear anything on 15 m.  Twenty metres seemed very noisy and signals were weak.  Nevertheless, I was really pleased to make a lot of contacts with stations in the UK, as well as some to Australia, NZ, parts of Canada and a few other locations.  For the first time ever I heard a station in Singapore too, but was unable to make contact.
I’ve attached a couple of pictures I took this morning of my QTH on the North Klondike Highway north of Whitehorse and of my station.  You may be able to see the end of my doublet antenna where it is attached near the top of the tall tree just to the left of the house.  My radio is a Yaesu FT-ONE.
Thank you for your efforts with the Commonwealth Contest and to the participants who make it such a pleasure to take part in this event.

Allen Wootton, VY1KX

Bob – here is my report on the 2020 BERU, thanks.

So glad I made the effort to get back in the BERU – Just managed to get my 80m shallow vee up to about 45 ft on Friday night using some bendy 3″ plastic pipes which fell over a couple of times during erection !! It was meant to be a temporary antenna but after all the effort I think it will continue to be an eyesore for a while. The 4el KLM is only about 40′ fixed and pointing 60 deg. but did not do too badly in the end. Had an amp failure on the old SB201 when the relay wire to the swr bridge seemed to have melted and made me deaf !! So after a quick pull down and an equally quick solder job – got it going again !! Desperately tried to snag ZD7BG on 15 but he was focused on EU, also heard my neighbour ZF2CA from the back of the beam but he could not hear me. Good to hear some still familiar calls like G4BUO he was loud !! The HQ stations all had big signals too – the lack of multipliers and VK/ZL’s let me down this year.

80 and 40 was very hashy throughout the entire contest – I got a very slow start as I was using and learning the new SD logging program for the first time after coming from the old pen and paper logging 23 years ago !!. It is great when you get going eventually !! Now if only I can get it to key from the keyboard – oh well, I have another year to figure it out.

Thoroughly enjoyed it although slightly handicapped by a quadruple bypass and arthritic fingers !!! Covid19 hit us here on the island earlier in the week so there were many family concerns, but the show must go on hi !! Hope to see you all next year……

This is what it looked like in the end, less anything that I got wrong of course…. SD check was a breeze !!

Sorry Bob, I sent a brief run-down to Colin CWH, our team captain for World Travellers but fogrot it hadn’t gone to you too!  Well done by the way on your own effort, excellent signals on 4 bands.
The decision to go to Turks & Caicos was largely driven by increasing inability to cart multiple large suitcases around the styx, hence the need to find what is essentially a ready-made station, in other words a rental shack.  After a number of fruitless enquiries, I settled on Jim Jordan’s very nice villa  on Providenciales, which is equipped with a basic Elecraft setup, together with a SteppIR 3el with 40/30m loop and a rather low 80m dipole.  It soon became clear that this setup had been largely tuned towards the ARRL events rather than CQWW, which would need to perform in all directions.
The benefit of the SteppIR is that it can be configured as a dipole by retracting the director and reflector elements, leaving me with what I had thought would be rotary dipoles for 10, 15, 20 and 40m.  Unfortunately (not declared until after I had arrived) the rotator had ceased to exist some months previously and turning it by Armstrong method wasn’t really on at relatively advanced age and degree of decrepitude.  Nevertheless, a couple of hours using this together with the barefoot K3 appeared sufficiently promising to consider a Restricted entry.  The villa is high up with outstanding sea views to the north and north east and this probably helps.  Having switched off the pool pumps and pulled a variety of wall warts (the shack only accounts for a small propertion of lettings) the site also proved nice and quiet.  I had  brought along my own P3 which was  missing from the station but I was disappointed to find that there was no second receiver fitted to the K3.  CAT control, which has been the bain of recent events, was however faultless.
We arrived at 7PM on the thursday before BERU and had just enough time to visit the local weekly Fish Fry event, a mile along the beach road before collapsing for the night.  Luckliy, Jim had run ARRL SSB the weekend before and had left everything pretty well set up, so it was only necessary to create a new SteppIR antenna with collapsed parasitic elements.  This took longer than anticipated because it had to be done separately for each band and then the driven element optimised for SWR.  Still the station was ready to go  by mid-afternoon on Friday, soon followed  by an early retirement.
Well, it’s true, keeping awake for 24 hours when approaching one’s dotage is non-trivial!  I really struggled over the last 6 hours, but then there wasn’t so much going on anyway as the end approached.  Looking at the log, it doesn’t look as though I napped for longer  thasn asbout 15 minutes.  Hard to comment rationally on conditions, having no experience of the station here but 80 in particular was disappointing to the UK, with lots of absorption.  I spent ages trying to make it with Nigel but signals were too poor and fluttery.  40 was marginal and nothing heard from him on the HF bands.  15 was open on and off all day to the UK and the P3 came in really handy to catch the “on” times.  I also spent an unreasonably long time chasing VP2VB and finally made it on 2 bands.  Signals were never wonderful on 15 and so i never  bothered with 10m.  Had the dipole been rotatable it might have been worth looking for Brian 9J2BO but the QSO with him on 15 was marginal anyway.
VSWR was quite manageable with 100 watts on all bands but I’m not sure how it would have worked with higher power. For me, a highlight was following the other Nigel 6Y5HN, who was a regular in the ’90’s but not heard since, so his “guest” entry this year was quite special.
So here we go:
80 – 101 QSOs, 36 bonus, 0 dupes
40 – 280 QSOs, 71 bonus, 3 dupes
20 – 253 QSOs, 48 bonus, 4 dupes
15 – 46 QSOs, 16 bonus, 0 dupes
Total 680 QSOs, 171 bonus and 6820 points.
I was disappointed not to have made either 700 QSOs or 7k points but there was literally nothing to be had in the last hour.
Thanks to all for the QSOs, everyone in the World Traveller Team seemed to be doing very well, although some of the numbers being  touted by the big Canadians were pretty frightening.  I think there’s little doubt they will walk off with the team competition this year as most of the VK/ZL  numbers were comparatively low this year.
73, Peter

Propagation from VK4CT

Hi Steve,
Thank you for your comments and helpful insight.
Certainly does appear that the propagation was with me this year. Barry VK2BJ commented on similar propagation differences from Sydney.
Indicative path openings from Queensland (Ocean View) to North America (NA) on 20m, 40m, and 80m are shown in the table below. The data is collected by my reverse beacon and forwarded to the RBN. Anyone can freely download and analyse the RBN raw data for any reverse beacon. I find this data useful for planning ahead.

Both paths to NA on 20m and 40m were clearly open from Queensland (Ocean View) – especially the long-path.
A multi-band vertical antenna collected all of the VK4CT reverse beacon spots.
Limitations:
Some spot counts are understated because my beacon stops while I transmit.
The table only provides the number of spots.
This table does not show variations in Signal to Noise Ratio (SNR).

I planned to do 24 hours Open assisted but it didnt turn out like that.
I have spent most of last year and early this year trying to upgrade the 80 and 40m antennas with some success.

80m After playing around with various vertical set ups I settled on a vertical full wave loop, which modelled out OK but wasn’t as quiet on receive as I thought. Much more work needed on this. Not much space for Beverages here , maybe a sneeky one round the local field margin etc.

40m I changed the 3 element vertical I used in 2019 to a simpler 2 element as I found that the extra complexity of the 3el wasn’t really giving me much advantage. In tests earlier in March I found that just being able to beam east-west was fine for most part but that my west noise floor is much higher than the east ( local house line and the surgery ) I built a noise cancelling circuit and it worked really well enabling me to null out a lot of noise. Just needs automating for 2021.

But being a compulsive fiddler and at the last minute, I couldn’t help putting up a north south 2 element and all that did was to mess up the east-west front to back! You would think I would have learnt something over the 20 odd years of BERU.

20, 15 and 10m I used the Optibeam and the separate 4 element on 10 ( not that that gave me much just 3 HQs )

Conditions
10m Dead, except for the 3 HQs no point in CQing. Pity as I had heard the TO7 in the week but couldn’t get more than a ? so thought that 3B8 would be a long shot.

15m Very spotty, short openings tricky to catch. V31GX went from a real S9 to S0 in a matter of a few minutes. VY2ZM was very loud but at the same time the other VEs were just whispers. Very similar to 2019.

20m Very active with propagation all over the place. Round the world echoes again on some of the big G signals!

40m I am pretty sure that 40 was open for DX for the whole 24 hours – hidden a bit behind EUs and I therefore think my work with the 40 antennas and noise cancelling has enable me to hear a lot better.

80m Work in progress. VKs and ZLs, those I heard I managed to work – just need to hear more of them! Everyone was crammed into a narrow slot it seemed to me so I got crunched a few times. Apologies to those in the queue when I sent the wrong serial to 6Y5HN and stumbled to correct it.

Operating.
I had a series of local problems on Saturday evening which rather changed things. I had lost so much time in the evening I decided to just do 12 hours. When I restarted at 6am on Sunday our telephone and broadband had failed. I created a hotspot with my mobile but WinTest would not transfer spots to the bandmap. (Much later on Sunday and after a lot of head scratching or was it head banging, I found that the internal routing codes between the WinTest Telnet and the main programme had mysteriously changed themselves.)

So back to good old tuning the band, and you know what, you find a lot of bonusses that way which don’t get spotted.

Prefix list. 3B8(2), 5B, 5Z,6Y(2), 8P,9G, 9J(2), 9H(3), 9V, V3, V5, VEs, VK,2,3,4,6, VO1,2, VY0,1,2,VP2V,VP5, VU, ZB2, ZD7, ZF, ZLs, ZS1.

Overall, still learning, more antenna work. Thanks to everyone for a great contest.

VK4WIA Sunshine Coast Amateur Radio club finished with a score of 1845 from 71 QSOs
Antenna were inverted V 80 40 and tribander 20 15 and 10.
It was a bit shambolic in organisation I ended up side swiped by the start of the hockey season and the other guys had to be left to their own devices.
We think we can actually do quite well from the clubrooms and will be back better organised in 2021

17x VK on any band (Same as last year)
9x ZL on any band (Down 1 from last year)
I operated MW7X from Angle Nr Milford Haven to get away from the local noise here and have a break away from work. I travelled down the M4 over Thursday lunchtime and traffic was very light and felt weird, even Newport (Gwent) was quiet.

On Thursday evening I set up the 40M vertical to get me on the air and I set up the other antennas on a warm and sunny Friday morning out in my tee-shirt and Wellies. Antennas were (For the start of the contest – I’ll come to that):

10/15/20M vertical/GP ad-hoc 20M GP with parallel wires/radials for 10 & 15M. (28M of Westflex + 3M of Mini-8 with choke)
40M vertical with 2x elevated radials (Radials on the fence = 33-Ohms, radials elevated above the fence = 50 Ohms) (15M of RG213+10M of Mini 8 with choke)
80M Inverted L – 14M tall with rest down at an angle, 25-Ohms then matched with ATU at base in a Tupperware box (My wife does know). 3x radials running down the wire mesh fences. (32M of Mini 8 with choke)

Pre contest testing on Saturday Morning – hearing on 80M FT8: ZL7 (Worked), FO, 3D2, KH6, ZLs all working each other. Noise floor on IC7300 S2 (S9+5 at home on same rig/antenna).

I found the contest very tough, enjoyable/interesting, but very very tough, N1MM+ says I had no runs of 10+ QSOs, well, actually my biggest run was 3 QSOs spread over 15 minutes. I had around 10 replies to my CQs and the rest were all S&P.

I’m usually a Writelog user and I’m used to a live window telling me how many hours ‘ON/OFF’ I’ve had, but all I can find in N1MM+ was the text report that it produces. But N1MM+ worked great this year, although I had to turn ESM off as I kept getting in a muddle.

Saturday night we had a big storm – My wife rang me at 2150 and as we were talking 80M went dead. I made a few more 40M QSOs to get to 12 hour contest time then went outside to look at the problem.

The pole supporting the 80M L had broken on the top of the second section, so the top 10M of the pole was laying on the grass. Even though I had guyed the pole on the top and it appeared to be very stable and the wind had just pushed the middle out. As a precaution I took the 40M vertical down and went to bed.

I was up at 0500, no wind,, dead calm, repaired the 40M vertical which had lost a radial in the night, somehow! and I bungeed the broken off 10M section of GRP pole onto the fence and pulled up the wire back to an 80M inverted L, so now 10M vertical and 10M sloping down, it just needed a little quick tweak on the ATU using the analyser. At 0600 I was back on the air…

The problem with a low noise floor and low power is that you think you are louder than you actually are. When you hear a VK or ZL CQing away just in the noise more than likely they will not hear you.

Some apologies:
5Z4/G3AB – I sent the wrong serial so I logged the serial I sent, which looks weird in the log.
G3DR – Even though I ‘knew’ it was an HQ station I still paused, then fudged the QSO, but we got there in the end, sorry!

Also a good heard but not worked was 8P6DR – Richard was Q5 on 80M at 0839 CQing away.
For next year? I’ll probably do the same again, but bring a sturdier pole for 80M!. For 10/15/20 I will try to assemble a selection of end fed verticals.

But why vertical? Firstly the QTH is an ex-MOD and Loran Tx site. The whole area is covered by copper coated steel radials and also a steel mesh grid around the redundant mast foundations. In CQWW CW I had a 15M 3 ele Yagi at 7M high (Which was the highest I could go due to the wind), a centre fed vertical dipole and a Hustler vertical on the fence. The centre fed vertical dipole was 2 S Units up on the hustler but was roughly equal to the 3 ele Yagi ‘when the Yagi was pointing the right way’ so 90% of my CQWW QSOs were made on the vertical.

PS I’ve attached a pic, if there’s a link the 80M antenna on the left is ‘post storm’..

Well done Dave, on a great score. I am somewhat surprised that I would even be ahead on QSO numbers at some point. It must have been pretty early on in the contest.

I went back to look at the log to try to understand the ‘differences’ – apart from the obvious – and I am certain it is nothing to do with sleep! I did not change the default in Wintest so the software probably thought I was mostly AWOL after about 0100. In fact, I only slept from 0300 to 0420. The rest of the time I was trying my best, it was just not enough. (PS I did hear a repeating message on 80m before I collapsed. The shack must have been quite warm when you awoke, assuming that was you J ). Looking at my QSO rate it was a very steady low 20 per hour until midnight, then it just died, everywhere. I made only 20 Qs between 0100 and 0600, accepting I was QRT for 90 mins, and only 3 of those were on 40m, which was essentially gone for me. There was a mild lift in rate after 0600 but not enough to catch up.

On 80m I worked 6 VK and one ZL in the afternoon/evening and, apart from VK7GN, all were actually easy QSOs – I mentioned VK2BJ just at my SS before, ZL4TT was actually also a very good signal at that time. I think the ‘difference’ is spread over 40, 20 and 15 when I think you were able to make more QSOs therefore you will have max’ed out on the call area bonuses whereas I didn’t/couldn’t. I was trying, I just neither found nor raised enough of a stir!
