wythall radio club

All roads led to the operating room at  Wythall House recently as The Friday Morning Club met again after a long absence.

With the 240’ doublet in action David G7IBO was able to see if his recently assembled QRP lab QMX mini transceiver would come to life and  with John M6KET  on hand (and using David’s home-made paddle) worked Nigel G4BSW  on 40m with 5 watts..  (THE QMX ? -an excellent little radio with crystal clear audio).

In a quiet corner Chris G3YHF was anxious to try the Club’s 6m beam  and rotator and enjoy the recent excellent conditions on this band: alas the conditions did not cooperate on Friday morning but contact was made with fellow member Martin G8VXX/M on his canal boat at the Black Boy Pub in Knowle, Warwickshire, via GB3WL and 2m FM. And half a QSO with an EI on 2m ft8.!

6m not responding but Chris able to contact Martin G8VXX on 2m

  On another table Phil 2E0WTH assembled his carefully thought out rig- in- a box and magnetic loop and Martin 2E0XFI brought in his very neat Icom 705 and lap top to try the magnetic loop on ft8.

Neil and Debra popped in to say hello. (Perhaps some satellite operation next time ??!)

Witnessing this hive of activity was Winston 2E0EGP  and Neil G1TCZ and Debra.

Neil’s account of his help in tracking the escaped  Gyrfalcon can be seen in the recent edition of Radcom.

With the success and support for  this opening of the Club on a Friday morning it is hoped to make this a regular event , meeting on the third Friday of each month.

Our next meeting of THE FRIDAY MORNING CLUB therefore would be on Friday December 20th

Watch this space for confirmation of date and times.

 THE CLUB HAS HAD ANOTHER BUSY YEAR

After last year’s AGM we published a programme of activities for the year ahead.  This was added to and adapted during the year.  It helped us make sure there was something of interest for members each month, usually on the first Tuesday – and sometimes we had several activities in a month!

 THE PROGRAMME FOR THE YEAR AHEAD IS ALREADY UP ON THE WEBSITE

I think the biggest development this year was our ‘August Tuesday evenings on the lawn’ – trying out antennas, learning to use a nanoVNA, operating radios, nattering and generally having fun.  This even encouraged some members we hadn’t seen for some time to come along.

Like all good ideas, this emerged from our members – a couple of members wanted try out some antennas, and after the first night we just carried on for the next couple of weeks taking advantage of the fine weather!  It provided an ideal opportunity to try out the vertical antenna kindly donated by Chris G0EYO.

Sadly, the weather wasn’t so kind to our big public events – Museum on the Air weekend at Transport Museum Wythall, Plug and Play (which had to be postponed due to a downpour) and the Stoke Prior Steam Fair.  We also struggled to find enough members and transport to renew our involvement with the Steam Fair. 

The Steam Rally team damp but determined and cheerful

However good team-work and commitment meant that we were able to provide a high-quality demonstration of amateur radio in the two events that did run.  Having two HF stations and the satellite station plus occasional VHF operational during these events provides a lot of interest but also means individual members don’t have to be on duty all the time.

Other new developments during the year include John 2E0XET and Clive M0KNP’s club SOTA expedition to a very misty Titterstone Clee Hill, and Neil G1TZC and Debora’s work in putting together 70cm beam kits for the foxhunt in the park.  The Q and A round table was also positively received by members.

Neil with his immaculately presented Fox Hunt table .. thanks too to Debra

The web-site has been very busy under John 2E0XET’s editorship and with contributions from seven members.  I counted an impressive 42 posts over the last 12 months – all good publicity for the Club.  It’s great to have the occasional post from our DX member Kev G4XLO in Devon, and also his regular contribution to our weekly DX table round-up.

It’s very important for the future of the Club to be able to attract new members, and we welcomed 6 new members 12 months ago plus Garry ZD7GWM as an overseas member.  They’ve immediately become part of the life of the Club.  They bring skills and expertise that help us to ‘have fun with RF’, as our motto says. 

I’d particularly like to thank Garry for being willing to pop up on the satellite when we run events to amaze our visitors with the clear signal from St. Helena, leaving them puzzled as to why we can do this but the wifi in their own house is so poor!

Balmy summer evening activity on the ‘lawn’ out side Wythall House

One of the strengths of our Club is that members are fully involved in planning our activities.  I must admit when I first joined the Committee back in about 2014 I couldn’t understand why it didn’t meet on it’s own to plan events as usually happens, but I can see now that our Open Committee meetings set the tone for all members to be able to shape what the Club does and keep it active and developing.

I’m standing down this at this AGM after three years as chairperson.  It’s been an honour to hold this position and to work with members to help the Club move forward from the challenges of the Covid  lockdowns, reduced membership and a tighter financial base. 

I’d like to thank members for their suggestions and participation, and especially the Committee – John, Clive, Pete, Ian Reeve, and Ian Gilmore.  We’ve had to address such issues as the cellar rooms, the perpetually rotating beams, the Hamfest, the 30 years-worth of accumulated gear, and relations with the House.

COMING SOON: TUESDAY NOVEMBER 5TH THE DARTS ROOM. 8.30 PM

THE OPERATORS FIST CHRIS G0EYO EXPLORES THE CLANDESTINE WORLD OF WORLD WAR II CW OPERATORS .

Many of us will have read the stories of W/T operators during WW2 being recognisable by their style of sending, otherwise known as the Operator’s Fist or Fingerprint. In a book I have just read about Code Writing and Code Breaking in the S.O.E *. by Leo Marks, ** he explains at some length why it was important to be able to recognise the operator at the other end of the link. Agents sent into Europe by SOE often had a W/T operator accompanying them. According to Marks, W/T operators fell into two categories; those who sent from the wrist and those who sent from their elbows.

Apparently, the elbow senders where more consistent in their sending than the wrist senders. The operator’s receiving the W/T traffic (known as” Signal Masters”) had to distinguish between errors caused by “stress” or “morse cramp” – colloquially known as “morse mutilation”; (don’t forget,these agents are sending under extreme pressure. Germans with D/F vehicles were constantly hunting for them), or errors caused by the changing propagation, or “atmospherics”.

The Signal Masters could always distinguish between mis-transmitted groups and  morse mutilated ones for a very simple reason: poor atmopheric conditions affected all the code groups, often making the clear-text impossible to read, whereas an operator’s mistake affected only individual letters

S.O.E. realised that the W/T operator’s touch on the keyboard was as individual as a fingerprint. so detailed recordings were made of every operator’s “fist” before he or she left for the field. The operators were instructed to transmit every letter of the alphabet at varying speeds, followed by every numeral, but were given no warning that they were being “fingerprinted” to avoid self-conscious transmissions. Their dots, dashes and Morse hesitations were then transferred to a paper tape which moved at 16 feet per minute. This magnified even the smallest Morse dots by quarter of an inch, allowing an in-depth study to be made of every operator’s style. The  on square-ruled paper and lodged with the chief Signal Masters at the WT stations.

When the operators reached the field, their “fists” varied from message to message, responding to the tensions of the moment, but the basic characteristics were always present. Eventually the Signal Masters needed no fingerprinting charts to identify these characteristics: their Morse-trained ears were attuned to every nuance of an operator’s touch, and they recognised it at once. The Funk-Horchdienst (the German interception service) was equally adept. Its radio experts were able to counterfeit our operators’ style to perfection if sufficient numbers of messages had been intercepted.

Even so, if an agent or W/T operator had been caught, anyone else sending their messages back to the UK with a different fist would ring warning bells that the agent and/or W/T operator may no longer be free.

The Code-breakers at Bletchley Park also used this “fist “recognition system to track German operators as the units they were attached to, moved from one location to another.

Is 10 open today?

That’s the question many of us are asking as we wait for the summer doldrums to disappear and sunspot maximum conditions to reappear.

One way is to put out a call and see if anyone answers. 

When I first got my licence I was told it’s always worth calling on a band that seems dead – it may just be that everyone assumes the lack of activity means it’s dead, when in fact it’s open!

Another way for voice mode and CW operators is to see if they can hear any FT8 burbling on 28.074USB.  If there is, decoding signals may indicate what paths are open.

Then there is the VERY extensive beacon network.  There are beacons on all amateur bands, but 10 meters is very well served.  

Most 10 meter beacons are found between 28.200 and 28.300, with some below and above these frequencies.

Beacons transmit their callsigns in Morse code, and may also give their locator square, power and antenna details.  Listening to them can be good practice for copying Morse code!

There is a recently updated list of beacons here.

Remember to enable CW on your receiver to get the correct frequency!

Early this morning I could only hear the German beacon DL0IGI, transmitting on 28.205. 

At lunchtime, I couldn’t receive this beacon – but instead the Faroe Islands beacon OY6BEC was very strong on 28.235. 

This is part of a comprehensive set of beacons in a radome to protect from the weather – shwon in photo left!

There is a special worldwide set of 18 beacons on 28.200 – the International Beacon Project. 

Each beacon transmits for 12 seconds once every 3 minutes at 100 watts.  There are then 4 x 1 second dashes sent at 100, 10, 1 and 0.1 watts. 

This lunchtime I could only hear 4X6TU in Israel, and I copied the 100 and 10 watt dashes, I could just hear the 1 watt dash, but not the 0.1 watt dash. 

Beacons may transmit a continuous tone between sending the callsign – so if you hear a tone, listen for a bit and see if a callsign appears.

At least it’s something to do if the band doesn’t have any QSOs on it!

                     Got to keep dry!!

Sometimes it just seems that the elements only need a whiff of our  ‘Easy-Ups’ to unleash their worst weather!

So it came to pass that under the approving gaze of the twin masts at Droitwich the team survived and indeed enjoyed a very productive  weekend of radio on CW, SSB. Satellite and Digital at this years Stoke Prior Steam Rally

Read on for first hand accounts from esteemed team leader Neil, G1TCZ and Ian M0LQY.

This happy band .. Neil, Gary, Phil, Ian and John

NEIL G1TZC writes:

For me, as always, the challenge is to be part of the team but stay as self-contained as possible. For satellite communication the site was as perfect as it gets. Plenty of south sky, short feeders and ground that you could get pegs in to easily.

Neil gets the operation station ready to go

On arriving on Saturday morning to set up the equipment I realised I had forgotten the second tablet and a feeder. Most of the station was set up and then a quick dash back home to grab the missing items was done. Although wet, there were a steady stream of people interested in what part old TV dishes had in our hobby. Explaining that a small amount of modification was required but they were basically still TV dishes seemed to be helpful for the level that people wanted to know about.

Most found it interesting that we were bouncing signals off a satellite at 25000 miles with a frequency used for wi fi. How come I have such a struggle getting wi fi from one side of my house to the other and you can do this, is often a question.

Also visiting amateurs from other clubs were welcomed to the stand, including a member of the Aberdeen Radio Club. For me, spreading the word about our hobby is almost as enjoyable as the operations side.

Ian and Darren swap a yarn or two. Darren and Carol are regulars at this event

As far as operation was concerned, around 35 contacts were made via satellite using SSB and FT8. As supportive of our events as ever was Garry, ZD7GWM, on St Helena with a rag chew during a quiet and rainy period. EU6DZ, was a very low signal with us but after a few attempts we managed to confirm the contact, sending a 4/5 report. Kadri, TA1D, often calls in to our activities from Antalya and did not disappoint. Also notable on FT8 was BG9HKP.

IAN M0LQY writes

On Friday evening with cars full to overflowing an intrepid group of WRC members set off to continue a ‘summer’ program of event attendance helping to promote amateur radio.

The event chosen this time was the traction steam rally nr. Bromsgrove. This rally in fact has much more than just the mighty steam traction engines with vintage cars, military vehicles, miniature working models and a steam organ all on display.

Ian M0LQY in digital mode

Using a selection of wire and vertical antennas and satellite equipment we made contacts throughout Europe and the UK. For the first time we utilized a recently donated vertical multiband antenna, this performed extremely well and was a definite success. Sustained by tasty bacon sandwiches and hot drinks (Thanks Phil) we bravely battled the worst of this year’s British weather.

Accompanied by a background of steam whistles, organ music and the adjacent mainline railway our hardy group cheerfully demonstrated the fun to be had by Amateur Radio. Clearly global warming having  took the day off tried its best to derail us off but was never likely to win. Great fun was had by all with many laughs and much interest.  People came to our stand to ask questions and hear us operating and of course shelter from the many downpours.

Saturday morning provided the best of the weather and we entertained lots of interested visitors. We were even visited by a fellow Radio Ham all the way from Aberdeen.  A couple of our group even stayed overnight preferring the elements to a warm comfortable bed.  Now there is commitment or maybe madness: the jury is out!!   (Commitment! Ed)

Anyway a great weekend of fun and enjoyment ending in dampness. The hope is that next year (September 20th-21st 2025 ) we get some better weather and we can begin again and WRC can continue with having fun with RF……

JOHN M6KET writes

….Yes we welcomed visitors from as far afield as Aberdeen George MM0TGG and old friend and current member Darren GW7HOC (last seen on a Sinclair C5!!) and wife Carol…Dave from the Wirral who helped me set up an instant sked with Bill G4YWD and many folk who just stopped by to chat including the Original Chairman of Bromsgrove Radio Club and his wife.

Chris’ CW table was visited and worked but on this damp occasion no certificates were awarded!!

We were pleased to see Gary G5RGS. He had made the effort to come down from Sutton Coldfield and the extra vehicle made all the difference in getting the three Easy- Ups down and back to Wythall.

ALL IN ALL A VERY SUCCESSFUL AND ENJOYABLE WEEKEND.. GREAT TEAM SPIRIT…AND WE CAN’T WAIT TO HAVE ANOTHER GO NEXT YEAR 2025.

COMING SOON: THE PRE-AGM MEETING .8.00 pm WYTHALL HOUSE TUESDAY 1ST OCTOBER

Members of Wythall Radio Club are not just based in the West Midlands: we can boast membership as far afield as  St. Helena , Cardiff and Torquay! Kev G4XLO is a tremendous supporter of our activities and a real QRP enthusiast. Here he writes of a successful low noise G4XLO/P outing to Daddyhole Plain. (Lovely place name: Ed.)

Kev G4XLO in relaxed mode with friends

“Ever since I moved to Devon in late 2016 I’ve wanted to operate portable as the noise level here in Torquay is really bad- there is so much noise it’s sometimes impossible to really ‘see’ what is out there .

I was quite lucky last year as I’d saved some pennies for a portable setup and has taken a few attempts to get it all working as it should and streamlining the setup so it deploys quickly. Sadly with family and work   I can’t get out as often as I’d like but these are the times I really look forward to.

I woke up this morning and as I have a weeks leave and the station manager (!) gave me a pass out to play some radio, I headed to my normal place I love here called Daddyhole Plain which is in Torquay and the spot I use is a clifftop car park (free of course!) located 300 yards from the Coast watch station.

My equipment is quite simple, this is the station I use:

1.Yaesu FT817ND

2.Yaesu SCU17 digital interface

3.LDG Z817 auto tuner + 4. Long wire supporter on a SOTABEAM 6m mast

          Kev’s very neat mobile set up.

The kit  can be quickly up and working and in 20 minutes I was fully charged on batteries and ready to go with  2.5 Watts maximum. 

It was a breezy morning on the plain so I had secured the mast with velcro supports (again purchased from Sotabeams.) 

Sotabeam 6 metre mast supporting Kev’s long wire mounted high on Daddyhole Plain

I initially started calling CQ on 20m FT8 and then calling individual stations

I worked just the 4 stations in about an hour, Balearic Islands, Mainland Spain as well as a new one for this year Algeria 7X3WPL which was just over 1200 miles away from my QTH; there was also an SSB QSO I didn’t log as I forgot the last letter of his callsign. (note to self, next time take paper and pen!)

There were a couple of people walking on the Plain who were keen to see what I was doing so I spent a good 20 minutes explaining what Ham Radio is and how we communicate using different modes; they were witness to my HB9 SSB QSO. (Incidentally he gave me a 5 by 2 report) 

Another reason I forgot the last letter of the call for the log as I was busy explaining how the radio was working !!

The breeze picked up…. the mast fell down…..  so time to head for Tesco up the road from where I was to get lunch for the XYL and the junior op!!

A morning well spent  and  some very satisfying  QSO’s with  very low power.”

WATCH THIS SPACE FOR A RESCEDULED EVENT

Wythall Radio Club members will be demo-ing their radio equipment at their ‘Plug and Play’ event this Sunday 8th Sept.

Come and visit us!

We’ll be in the field behind Wythall House, near the Scout Hut.

We’ll have antenna masts up and Club flags flying!

If you do visit us, don’t forget there is a modest charge to use the Wythall Park car park until mid-day.

More sunny Tuesday evenings extended Wythall Radio Club’s portable operation from the lawn outside our base.

On our third week of activity, we had three stations operational. 

The Club call GX4WAC/P was activated using Neil G1TZC’s portable satellite gear. 

This resulted in an impromptu net through the geostationary satellite QO-100 with DJ4FF (Robert), HB9FIY (Chris) and our new Club member Garry ZD7GWM.

The station was the usual ground-station with the 60cm folding dish. The Goonhilly webSDR was used on receive because the satellite was partially obscured by a tree, but the up-link signal into QO-100 was enough to be given a 58 signal report from receiving stations.

Martin 2E0XFI/P set up on another part of the lawn and was delighted with the results using his IC705 and 17 foot-long telescopic vertical, achieving 5 watt FT8 QSOs with Indonesia and 3W9A Vietnam. 

To complete the trio of stations, Chris G3YHF/P brought a home-made 20m delta loop on an 8m pole. 

With Ian, M0LQY, he worked around Europe on the key and had a very pleasant chat with Torgen SA5TBE on SSB – 59 both ways. 

Finally, the light faded, the midges came out and the lawn was emptied of kit and activity.

But that’s not the end of the story!

Our portable lightweight antennas inspired Ian M0LQY to search the SOTABEAMS web-site, where he found a design for a multi-band doublet. 

Quickly purchasing some lightweight SOTABEAMS cable and spaces, he had one constructed within an hour. 

For the doublet centre, he crafted a small piece of plastic tube with two holes drilled in it and a cable tie to fit the top of a telescopic mast.

The following week the doublet was quickly raised on Chris G3YHF’s 8m telescopic mast. 

The mast survived some bending as the two doublet legs were untangled – as the photo shows!  But within a few minutes we were on the air.

Using an FT817 and small auto-atu, a very low SWR achieved on the higher HF bands and 5 watts of FT8 gave PSK-Reporter spots across Europe.

Even as dusk turned to night, members – and visiting RSGB District Representative Martin M0JZT – could be seen discussing the results of Ian’s experiments.

Members went home for an early night or retired inside the Wythall clubhouse for refreshment, and to continue sharing experiences and ideas.

Very pleasant evenings! 

Our Club meets every Tuesday evening and visitors are always welcome there and at our special events, the programme for which is on our web site.

Our next big event will be ‘Plug and Play’ on Sunday 8th September on the rugby pitch behind the Wythall House complex. 

Members will be bringing along their own equipment to operate, using power kindly provided by Martin G8VXX’s generator.  Come and visit!
