New Foundation licence holders will hopefully soon be on the air, reports Chris G0EYO, our Training Coordinator.

“In our last on-line Foundation course, which finished in May, 9 students completed the course. 

Seven have let us know their results, and 5 passed – the youngest was 10 and the oldest was 80.   Most of our candidates were Midlands based.

We send our congratulations and hope to contact you ‘on the air’ with your new call signs!”

Our next online Foundation Course will start in August 2021.

Please contact Chris G0EYO at  g0eyo@blueyonder.co.uk  if you would like to take the course – more details on our Training pages.

Stuart M0SRZ is the 2021 recipient of Wythall Radio Club’s Lew Williams Shield.

This annual award recognises a member’s progress with CW (Morse Code), and is in memory of Wythall Radio Club’s former CW tutor and President. 

Stuart obtained his Foundation Licence in 2016, followed by Intermediate and Full in the same year.  He took the CW Academy Beginner Course in spring 2019, and has been making great progress ever since. 

Stuart won the Lew Williams Shield in 2020, but his commitment to continuing with the CW Academy course since then means he holds the award for another year.

Stuart tells us: “The CW Academy courses have been instrumental in my progress. However, the vital element is the support, encouragement and example of a club such as our own.

The gentle introduction to the mysteries of Morse, and the inspiring, consistent example of John 2E0XET, began my present endeavour to learn and, hopefully, attain some degree of proficiency.  And that banner is now carried on by the Club’s current CW tutor David G0HVN.  

A history of CW teaching that started with Lew Williams, long before I joined this Club, continues to this day. 

Reading about the CW exploits of many club members provides further encouragement.

I shall try to earn that honour during this year by taking the CW Academy Intermediate course during September/October – and that is going to demand a lot of practice between now and then! ” 

Stuart commends the free CW Academy courses: “They are quite intensive – two online hour-long sessions each week – and you really have to put in the practice every day. If you’re interested take a look at https://cwops.org/cw-academy/“

Latest News from Training Co-ordinator, Chris G0EYO is that the next on-line Intermediate Course is planned for a 28^th June 2021 start and will last for 10 weeks and the next on-line Foundation course is expected to start in August.

The Radio Society of Great Britain (RSGB) is now offering remote invigilation in people’s own home for online examinations at Foundation, Intermediate and Full Licence level. You can read further information on the RSGB website here. 

We are not yet in a position to offer paper examinations at the Radio Club.

The RSGB have also permanently removed the need for practical assessments for the Foundation course at this time. Practical assessments at Intermediate level are currently suspended until such time as the Covid lockdown regulations permit their resumption. We hope that they will remain suspended for the duration of the next Intermediate course.

Wythall Radio Club member Clive M7OCB has been making the most of his new call while out portable on the high ground!

My wife, Penny and I have a static caravan in Cumbria on the edge of the Lake District and spend a good deal of time in the area throughout the year.

We enjoy walking the Fells and sometimes the lower Peaks with our two dogs. Following on from the restrictions due to Covid being lifted we were keen to visit the van for the first time this year.

Keen too to give my trusty Baofeng handheld a chance at some high level QSOs in the outdoor environment!

So to the Lakes at the end of April for 2 weeks. I have become more confident in using my radio and keen to add more QSOs to my Log Book and this trip seemed to be the ideal means to do this.

On the first day we were doing some minor maintenance on the van.  I had the radio on the van decking and overheard a SOTA activator calling CQ SOTA on Coniston Old Man. Didn’t manage to get back to him but it inspired me to actively listen out for CQs.

Over the next few days I had SOTA contact from a High Fell Whitbarrow (a QSO of 31 miles) which further inspired me.  

On Black Crag (323m) I called CQ and had a number of QSOs. 

At this point I learned the importance of a note book as I was unable to Log these contacts! Another successful session on Birkrigg Fell (116m) furthest QSO to mobile at 33 miles.

I have now registered myself on the SOTA web site and plan to do some Activation during the summer when we visit again.

Big scores were reported in Wythall Radio Club’s April DX challenge – but it was a two-horse race!

With warm Spring weather tempting members’ activities outside the shack, it was left to Chris G0EYO and Lee G0MTN to chase the DX.

Using the 80 and 20 meter bands, all continents were contacted except Australia/Oceania and Antarctica (always a challenge!). 

Well done Chris on 126 countries worked using a long wire and FT8.  And even though the nights are getting shorter, 80 meters still produced 42 countries!

The countries that Chris and Lee contacted in the other 5 continents included Hong Kong, Venezuela, Mozambique, Canada and Albania.

In addition, Lee worked 10 countries on 6 meters.

“How low can you go?” was a theme of Wythall Radio Club’s Easter Contest 2021.

Chris G7DDN made his 37 contacts with other Club members using his trusty FT817 running 5 watts into a 2m/70cm collinear, and achieved 3rd place in the VHF/UHF category.

Not to be outdone, Allen M0PPX made a 0.3 watt QSO with Kev 2E0NCO whilst en route to the Lickey Hills using his new Yaesu FT3D.

Meanwhile, Lee G0MTN connected his Kenwood handheld to his EME antennas (normally used for moon-bounce contacts), wound the power down to 50 milliwatts, and also made a contact with Kev 2E0NCO!

On the space theme, Chris G3YHF send a greetings message via the International Space Station digipeater – 00:00:01:40 : G3YHF]CQ,NA1SS*,qAR,CT1EBQ3::NWS :Happy contest Wythall RC g3yhf via ISS 

This didn’t count for the contest, which requires QSOs with any of the Club’s 80 or so members, but is in the spirit of our motto – ‘Having fun with RF!’.

John 2E0XET also tried some novel QSOs.  Normally found on CW and often using QRP, he was tempted to have an HF SSB QSO and also try out his new Baufeng handheld on 2m to have his first contact with Kev 2E0NCO!

First place in the 2m/70cm section was Kev, 2E0NCO. 

Although a big signal from home, he also spent several afternoons on the Lickey Hills and managed a contact with Rob 2W0MEX in South Wales – one of several members spread across the UK and abroad.  This was no mean feat on 2m FM!

Kev wins the Colin Baker G6ZDQ Shield.

Miles 2E0YZW was a close second and Tim M6OTN and Clive M7OCB tied for the highest placed foundation licencee in this category.

In the ‘all modes and bands’ category, David G7IBO amassed a huge lead over second and third placed Chris G3YHF and Lee G0MTN.  He made 71 contacts over the 5 days of the contest and worked 28 members for a score of 1344, more than double the second place score!  He wins the David Dawkes G0ICJ Shield.

Juliet M6RSC was the highest placed Foundation licencee in this category.

With May approaching, Club members now turn their attention to their annual More Appreciation Month and the Lew Williams Shield.

Warwick G4WMH offers his reminiscences following the RSGB President’s comments on the passing of its Patron HRH, The Prince Philip, Duke of Edinburgh, particularly with reference to his support for the Society’s 75th Anniversary Convention in 1988.

GB75AC was a Super Station to celebrate the RSGB’s 75th Anniversary Convention.  We operated for 10 days from a temporary “cottage” located next to Pendigo Lake in front of the NEC. 

The station was supported by all of the major importers and many UK manufacturers with peripherels and amplifiers etc.  We also had Icom, Kenwood and Yaesu rooms.

The station had the capability of “all HF bands plus 2m & 70cm” and many mode operation for 24 hours a day.  There was a very impressive antenna farm with 100′, 80′ and 60 ‘ towers and lots of wires. 

We waved some 2m & 70cm satellite antennas, but lacked the manpower to make any satellite contacts.

The camera shot was not wide enough to pick up all the antennas, some of which were quite a distance from the station including the verticals and wires.  

The signal flags in the outside shot spell out GB75AC – they were full size navy flags – very heavy with lots of windage so we did not fly them high.

We were inundated with visitors, including foreign royalty, government representatives, presidents and officials from many overseas societies, some celebrities and at least one astronaut, not to mention many DXers from around the world, many of whom wanted to operate the station. 

This was a time when RSGB Conventions were huge.  In those days we knew the NEC well and amateur radio operation was common from a wide variety of public and trade shows.

There was great teamwork.  Working closely with the RSGB, the station and the Prince’s broadcast was pulled together by an enthusiastic team from midlands clubs – Bromsgrove, Midland, Solihull, South Birmingham, Sutton Coldfield, Wythall and others. 

Guest operators from around the country signed-up to join the team, bringing amateur and professional expertise and borrowed kit to the station. 

One thing was definitely missing – there was no computer logging in those days.  Despite valiant efforts from team members we never got a stable network (or data).  However, conditions were pretty good at the time and we really did work the world!

A great challenge was the planned live broadcast of the Patron’s speech which we actually achieved on time – simultaneous transmission which we broadcast to the world on 80, 40, 20, 15, 10, 2 and 70cm.  What a pile up of call-ins once it was finished! 

To make the broadcast we required a high qualty cable link from the centre of the NEC, running through underground passages and under road culverts to get from the exhibition to the station.  And we had to get the very expensive cable undamaged back to the contractor who loaned it, ready for their professional installation just a few days later!

The next challenge (soon after the broadcast) was to exchange grettings messages between the Duke and Windsor Castle.  We had media pressure for this to be an exchange between His and Her Royal Majesties.  It seemed like a good idea at the time!!

We considered all sorts of options, including some fancy encryption technology, which was great fun to play with but even the professionals could not guarantee that it would work on the day.  We considered that it would be a nice thing to do but we only needed a nutter or two to ruin everything! 

The solution was two fold: 1. The Duke would pass greetings with a representative of the Society who would be located at Windsor Castle and who would return the greetings and thanks for his patronage. 

We were still concerned about unwanted interuptions and hit upon solution 2: We would not use an amateur band – we selected an “obscure” military frequency.

The Duke was standing in front of the then latest Yaesu showing a 40m frequency, whilst the microphone was actually connected to my trusty FT902DM in another room, with a separate antenna on the roof and controlled by me using a hand PTT and prompting the overs. 

It all went very smoothly with a nod of approval from the Duke!

Andorra, Albania and the Azores were amongst the countries contacted by Wythall Radio Club members in their Winter DX Challenge. 

The aim was to have two-way contacts with other radio amateurs in as many different countries as possible on the  40 and 160 meter short wave bands.  This Challenge ran through February and March.

With his Foundation licence, Tim M6OTN showed what could be done on 40m, working 90 different countries.  All this with low power and a vertical antenna (photo).

On Top Band (160m), Lee G0MTN worked 85 countries – great going with a mix of digital and CW modes. 

Club members had lots of fun talking to people in other parts of the world.  They used digital, voice and Morse Code transmisions at all times of the day and night.

Here’s a list of countries we contacted.

Ian M0IDR has been working on one of these classic rigs…….

The Yaesu FT101z or FT101zd are classic Hf transceivers from the 70’s and really solid made.  They feature a valve PA and driver and with the zd, a digital display of frequency. 

Photo left: Front of the transceiver which is a Mk1 the D in ZD denotes factory fitted digital frequency display. You will see this is missing as it is in pieces on the repair bench.

With some TLC these can be ready for another 40+ years of service.  Having sorted out one for a ham near Stratford,which had been stored for years, it spurred me on to find another example for myself.

The weaknesses in these rigs are: digital display issues, audio amplifier failure, connector issues, driver to PA capacitor leakage and dry joints on some circuit boards. 

Having found an example that looked decent, I already was aware that the S-meter and BFO dial lamps were intermittent and it blew fuses.  Well, it blew fuses because the fuses that were used were 2amp whereas the rig needed 3amp ones!  Correct fuse installed, receive works fine and fuse does not blow. 

It is so important to use the correct rated fuse, in this case a 3A fuse of the quick blow variety.  An example was the one I repaired for my Ham friend.  It had blown the fuse, and the replacement was a piece of lighting flex wrapped around it with a 13A fuse in the plug.  Yes it was “”fine”” on receive, but as soon as the PA valves warmed up there were fireworks inside the mis-matched PA valves with one of them dead short-anode to ground.  How it did not take out the anode choke remains a miracle.

However, after several hours on receive, the audio suddenly cut out just leaving the S-meter registering signals but no audio.  I assumed it was the audio chip that had failed.  I checked and failed to find an audio signal at the input to the audio amp. 

Photo right: A view of the underchassis showing just showing complexity of the audio and demodulation board with one of the power supply boards to the left.

The troublesone audio chip is on the rectangular aluminium heatsink.

However, this rig has the following external audio jacks: rear panel – line audio in;  front panel – phones jack and unlike other 101zds the phone jack also has a line out and switches both the output to the speaker and audio input to the amp.  Well,phones socket clearly had seen better days but was so buried in wiring that the only way to access it would be to remove all the controls and front panel.

Fortunately several insertions of a suitable 1/4 inch Jack plug cleared the problem. 

It is crucial to have service data with full schematics available together with diagrams of signal routing on receive and transmit to progress fault-finding logically.  In this case it helped but the wiring of the audio signal through the headphone socket to provide a audio line out was undocumented and unusual especially considering there was already a line out on the rear panel!

Dense component replacement makes voltage readings difficult and generally measurements are taken from the multi-way connectors which are plentiful on the chassis.

Photo right: The PA and bandswitching

Not shown in the photos, but above chassis there are 2 more circuit boards which have these white multi connectors and (fortunately) for the RF circuits, the boards plug in to multiway interfaces which are chassis mounted and make removal and replacement easy.

Spares are still plentiful and are usually sourced from rigs which have been parted out.

The electrolytic capacitors used in these rigs  in general are really good quality and although there are incidents of them failing,they are relatively few and far between.

Most rigs are parted out because of physical damage through being dropped, mains transformer failure, a PA meltdown or bizarrely frequency display failure.  Display failure is common and there are now “kits” to replace the readout with a LCD screen which can save the day!

Happy Days!
