MW0JZE HEXBEAM Project

Hi all,

About 18 months ago I was reading several articles about the HEX BEAM with great interest, work got in the way along with daily life etc so it was put on the back burner for a while. Around Christmas time 2008 Oliver MW0JRX told me he had bought the kit form from WI3USA. At the time of writing this he has since installed it and is happy with the performance so far. Chris G1VDP then informed me that he was going to make his own homebrew HEX BEAM. Well not wanting to be left out I set about collecting as much info on the antenna as I could with the help of Chris G1VDP, Gordon MM0GPZ (GEEE PEEE ZEEE) and the Yahoo group.

On a recent visit to Rob MW0RLJ’s qth he kindly donated a 3mm aluminum plate along with two KEE Clamps that are needed to fabricate the centre plate that supports the six fiberglass spreaders. Total cost so far zero, thanks Rob 

A trip to B&Q one Sunday morning and I had bought all the parts to fabricate the centre post. I have taken some photos to show you how I fabricated the center post. As I build the HEX BEAM more photos will be added.


First Job, drill the holes


Fitting the bolts, this is where the driven ellement will attach to.


Thats all the feedpoints fitted


Ecoflex 10 used for feedpoint coax, this will be weather proofed later


Removable end cap, handy for later inspection and weather proofing, the antenna is fed at this point


Coax feed leaving the centre post

More photos to follow as the project progresses.

Beverage RX Antenna

Details
I have tried to use a special receive receive antenna in the CQ WPX Contest. Team OM0A has run M2 category and beverage antennas was the last antenna that we have built on Friday’s evening. Luckily I was on the 80m band during the morning’s openning to Carribean and North America.

It’s a huge difference between inv.Vee and beverage antenna. Even though our location has a very low noise, the main improvement was in the attenuation of local stations. Not only stations from other directions, but also closest stations from OK and DL. Heavy QRM gone and I could copy sigs from stateside. Some of them was in the same strenght as on inv.Vee antenna, some was louder.

I break pile-up and start hunting W stations. Unbeliveble hour! Comparing to other stations from Slovakia, our result on 80m is better! I love beverage antenna.

How to built it?

CQWPX 2009 Phone and Updates on Activity

Chris Colclough
Chris Colclough
Details
Well we seem to have had a busy couple of weeks since the CDXC dinner. 

It all started with a trip down to the farm to take part in  the CQ WPX Phone contest. Chris did a single band high powerwpx_friday_2009entry on 80M, using the club call MC0SHL, and Oli entered on 40M using the club call MW9W. And what a weekend it was. Not only did we enter the contest but Chris also made, with help from Ant MW0JZE who joined us for the Thursday to set up the 80M antenna, a 30M 1/4 wave vertical - ground mounted with 4 radials - which worked pretty well. We managed to make 379 QSO's on 30M RTTY between the 26 March and the 30th March, not bad to say the boys were in the contest for most of the operating time. We also managed a few contacts on other bands using the 40M and 80M verticals tuned through the Palstar AT2K ATU, ending the full weekend with over 500 RTTY qso's.

Best DX on 30M was probably into Japan, but we also managed to work a number of US stations also. The next time I am down there I will also bbe setting up the antenna and radio again just to have some fun working this mode on this band. Chris is also on 30M RTTY working from home most days, although he doesn't have the room for the vertical he can get a inverted V dipole in and now has that up and running.

We were lucky with the weather too. Though it did rain as Chris was driving down. He set off from home at 04:00 and drove all the way down to the England/Wales border with clear skies, as soon as he got into Wales it started raining. And the Rough_seas_1_This_cliff_is_about_50ft_highrain lasted all the way down to Rob's. But after a welcome cup of tea and a catch up with Ant and Rob the rain stopped and we were able to work on the antenas in relatively warm conditions, all be it slightly windy - or should that be blowing a hooley?The skies had cleared and we had a clear day to erect the antennas and the sunset on this evening was stunning, and the photo's do not do it justice. 

The following week Chris was on holiday from work and managed to clean up his shack a little. And he entered the EA DX RTTY contest too. This was over the weekend of the 4th and 5th of April. Again only having the antennas for low bands I set out my stall on 40M and had lots of fun. Probably my best DX this time round was again out in to Asia, with a lot of US stations. Most contacts were with Europe, and I thank every one who called me for the contacts and points.

There then followed the 80M Club Championships organised by the RSGB. These allow all club members to get on the air from their home stations and pool their scores. These run from January through to July and are of short duration, only 90 minutes on alternating evenings through the month, and comprise of a CW, SSB and Data legs. Charles and ChrisMW0JRX_on_40M_SSB_Before_contest have been entering these events since January, and Ant and other team members are now joining in as they get their 80M antennas up in the air. Sadly Charles has been commited to another club for the past few years, but it does put a little friendly rivalry in to the contests - especially after each event we compare how we have done. As a club we are slightly behind Charles other club, but as there has only been a couple of us entering we feel we have done well. Maybe in next years club champs we will be top 10 all the way.

Then this Easter weekend Chris entered the UBA Spring contest. This is a slightly different type of contest and he only entered for some fun. You have to make contact with Belgian stations only on 80M SSB, and Chris' score - looking at previous years - will hopefully put him in the top 5 foreign stations.

Happy Easter to you all. And don't forget to look out for the club members on the air - especially on Wednesday evening 15th April as it is the SSB leg of the 80M Club Champs, see http://www.vhfcc.org/hfcc/rules/2009/r80mcc.shtml for full rules and information.

CQWPX Weekend brief report

Chris Colclough

Details

Thats it for another year. CQWPX Phone weekend is over.

This morning we took down the 80M vertical - which was a lot quicker than erecting it - without incidence. All the bits have been put away in to storage until we come down again in July for the IOTA weekend and CQWW in October.

We have left the 40M and 30M verticals up as Chris is staying on another day and wants to have some more fun on the bands. A full report and photographs will appear on here before the end of the week, and all logs will be uploaded to LOTW as soon as Chris gets home.

Many thanks to all who worked either MC0SHL before, during, and after the contest. And a big thank you to all who called or worked Oli - MW9W - on 40M during the contest assisting him to (hopefully) have a top 10 World score for Single Op 40M activation.

See you all at the next one, and remember to leave a comment in the guest book if you enjoyed the site.

GW4OH CQ WPX Events & Lessons Learnt The Hard Way!

Hi guys and fellow hams/surfers!

Well after a trip to Rob’s farm to help Rob and Chris erect the 80 and 30m verticals I returned home to give a solo effort from home a bash.

Plan was to use a ¼ vertical with 2 tuned raised radials and a Windom antenna to get the best of DX and inter G and EU. This did work to some extent but I had not used the Windom for quite some time and should have tested it better! The antenna caused quite a bit of RF to the PC which in turn caused problems to the radio! After crawling around on my knees under the desk in the early hours of the morning I managed to fit some RF chokes to cure this in a fashion, I could only run 250 watts but this was not a problem just something I had not counted on. I had a PSU fail on the pc which also needed replacing a day before the contest so it was not a good week for PC’s and me!!

High energy drinks for the long weekend


The Vertical was working well on DX but was causing TVI problems with the 400 watts so I also had to reduce power on the vertical to around 200 watts during the day, the vertical was in use mainly at night so this was not much of a problem although it was handy to switch between the two antennas to compare signals and reduce the noise level on times.

My conclusion of this weekends events.
Spend more time sorting my station out during the 2 weeks prior to the contest to cure these problems instead of losing my temper and my frequency. Because of these problems I lost interest and concentration and did not enjoy the event as much as I should.

CQ WPX Weekend

We arrived at the farm yesterday (Thursday 26th March) and managed to get the 80M and 30M antennas in the air, not without incident.

wpx_friday_2009_2The 80M antenna had been made from 5ft swaged poles, but we found it to be about 1M short so we inserted one into the poles and sadly it was a little too heavy for them and one bent! We are just glad this happened now and not at the end of October when we come down for CQ WW!

We have now built the 80M out of stronger aluminium poles and we have managed to get the full quarter wave up now. This coupled with the radials is making a good antenna. We also built a 30M ground mounted vertical, and we made a number of contacts on 30M RTTY last night. And again this morning w got on 30M RTTY and made a few QSO's before tuning the vertical for 20M and working a number on there also.

This morning we erected the 40M antenna and Oli has spent time this afternoon on 40M and had a nice pile up. Mostly with Europe, and I think he will be on later this afternoon again before the contest having fun. Th weather is being kind and the sun is shining brightly. Looks like we are going to have a classic SHDXG sunnset tonight, we will be out there withSunset_on_first_day camera andglass of wine relaxing before the off.

We will also be on 80M phone and 30M RTTY later, look for us around 10148 listening 10146 to 10147.

CDXC Dinner

The weekend of the 21st and 22nd March saw the Chiltern DX Club (CDXC) get together for their annual dinner and social evening at Wyboston Lakes, on the Cambridgeshire/Bedfordshire border. This was attended by Tim (M0URX) and myself Chris (G1VDP) - both very active members of this DX group and well worth visiting their website at http://www.cdxc.org.uk (see links pages). It was an evening of good food, good wine, and good company. Many of the UK's top dxers are among a_collection_of_dxersthe ranks of the members, along with some famous - or infamous in some cases - DXpeditioners and contesters.

Folowing a pleasant and uneventful drive from our home in the Midlands we were welcomed at the bar by Geoff G4FKA and Ian G3YBY, 2 friends from many of these dos. Tim's comment was "It looks as if it is going to be a good one again!" and he was not wrong.

Activities started with Nigel (G3TXF) giving a demonstartion of ARRL LOTW to all comers, and I think we all left with some new information somewhere along the line. I know there were one or two who had never used LOTW and was surprised how easy it is to upload your logs for confirmations. A few drinks in the bar followed before getting ready for the evening meal and the talk.

This years guest speaker was Bob MD0CCE, who gave a facsinating insight to his life and how he started on Manhattan island and now resides on the Isle of Man. Following the talk Neville (G3NUG) presented Bob with a CDXC Mug - now a rare commodity as no more will ever be produced! We then all retired to the bar for a drink or 2 before retiring for the night.

Breakfast was then another chance to talk DX and contesting with the boys, and catch up with who was going where next on their travels.

19th March 2009 80M CC

Chris G1VDP has been pestering me for a few months to join him in the 80m Club Championship contest SSB leg, last night I made the effort!

The contest lasts for one and a half hours with a Signal report and serial number exchange. The first 45 minutes went so fast that I was on serial number 90 giving me a 2 Q a minute rate, not bad for a small contest such as this. The TX antenna was an inverted L with 62 random length radials buried under ground at about 1CM and I used a Carolina Windom for RX from time to time due to high local noise. Power is restricted to 100w and the transceiver was the K3 by Elecraft.

Total Q’s was 150, not bad for my first bash at this small but seemingly very popular event. I will work more on my rx for the next leg and hopefully hit the 200 mark!

Hi guys

Unfortunately I am not able to join some of the members for this years WPX due to some family commitments that I could not change!

I will however be entering as a single operator, single band non assisted on 40M with high power.

The antenna to be used is a ¼ vertical with two elevated tuned ¼ radials at 48 inches above ground. I would like four but I am unable to fit these in my garden.



A report will be given after the contest; my call for this contest will be GW4OH.

It is just over a week before we head down to the farm for some on air fun in the CQ WPX SSB contest. Not all team members can make it for the weekend so we will be putting on single band entries in the contest, using the club calls MW9W and MC0SHL (Oli MW0JRX and Chris G1VDP) possibly on 40 and 80M. If any other members arrive we will then look at other bands and again do single band entries with alternative call signs.

chris_g1vdp_3Not only will we be taking part in the contest but we are going to have a station dedicated to 30M digital modes before and after - and maybe during if any member who is free wants to have a go. Chris G1VDP is going to put Wales on the air on 30M RTTY and PSK63/125. As you all know Chris enjoys his digi modes and has looked at the activity from Wales on the 30M band, and he sees that it is still a quite wanted DXCC on this band.

He plans to be active on the Thursday night on RTTY, look aroung 10148 for him calling CQ. If the pile up gets too big he will operate split listening 1 - 2KHz down. If there is enough demand he will also try PSK63, and PSK125. Again these 2 modes are under utilised from Wales.

If you want to arrange a sked please e-mail Chris G1VDP at the address in the contacts page.

Good luck and we hope to see you on the screen.

CQ WPX RTTY Weekend

Chris Colclough
Chris Colclough
Details

Well the weekend of the CQWPX RTTY contest has now passed us by and I enterd from home using the club call M9W. But as usual my plans for just operating as a single band entry went out the window. I was going to enter on 80M only and operate through Friday night, sleep Saturday and then operate Saturday night, grab a couple of hours sleep on theimg_0007Sunday, and then go to the end on the Sunday evening.

Never happened. I started well on the Friday evening with a good small run to the USA and Caribbean area. This then dried up so I thought I would have a go on 40M, and again worked USA, Europe and Asia. It was around 4.30 and I was strting to feel sleepy so went to bed.

I then received a phone call from a friend needing some help with a small job, so off I went to their house to help. I returned and thought get on 20M for a couple of hours, and then tried 15M with only 2 contacts. So on 20M I worked Asia, throughEuropwe to the USA. And by when 5pm came round I again had to leave the radio. I had forgotten there was a Northern Soul event at a local venue (see my website http://www.g1vdp.com) and I had promised my friends I would be there. So it was off out for a few drinks and a dance.

img_0001When I returned I had a quick tune and call on 40 and 80M with more USA and Caribbean worked. Sunday I spent again on 20M with a quick check on 15M. Ending the day on 40M with a final spurt on 80M.The final results were;

432 QSO's
1408 Points
253 WPX
Claimed score of 356,224

This is only a part time score due to the constant interuptions and the antennas were only dipoles - 80M, 40M and 30M tuned for 20M and 15M through my Palstar AT2K.

Don't forget we will be on from the farm in a few weeks in the CQ WPX SSB contest. Not sure how we are going to operate as yet, but it is looking like a 2 single band activation using MW9W and MC0SHL. Hope to work you in the contest.
