- SSB Field Day 2024
Cray Valley RS took part in the RSGB Single Sideband Field Day contest on the weekend of 7th and 8th of September from Gosenhill Farmin in Crockenhill using its contest callsign M8C/P. Several club members were on site over the weekend to operate and to help out. Operation was interrupted during the early hours of Sunday morning by lightning and heavy rain which forced the station to shut down for an hour and a half. There was also a technical problem with the TET HB33SP beam antenna tripping the amplifier when transmitting on the 20m band, but there were no…

- Summer BBQ 2024
The club held its annual summer barbecue on Saturday 3rd August. Last year club members had to dodge the showers, but this year, the weather was kinder, and after a cloudy start it turned into a gloriously sunny and warm afternoon. Around 40 club members attended, and it was nice to see many new faces including members who had recently joined the club after passing their foundation licence with Cray Valley RS earlier this year. A huge thanks go to all who helped with the barbecue, and a very special thanks to Kieran G8CHB for organising everything so well, yet…

Cray Valley Radio Society’s Toby Tiesdell-Smith M0TBS secured second place for the club in the 70MHz Trophy Contest – singe operator open section – using the club’s contest callsign M8C/P Toby’s equipment was a Kenwood TS2000 and a 4m transverter, and the antenna was a 4-element Yagi 8m off the ground, at an elevation of 100m above sea level. Well done Toby!
- Field Day : 19-21 July 2024
Cray Valley has entered contest field days on and off, for many years. The field day held on the weekend 19-21 July in Crockenhill was rather different, being held on a weekend when there were no major contests and the idea was that club members could come and go, and also bring their own kit and antennas and just ‘play radio’ over the weekend without the pressure of being in a contest. It was also a chance to use some of the club’s field day equipment which hasbeen woefully under-used in recent years. The weather was kind, with just two…

- DF Hunt 2024
This year’s DF Hunt was blessed with good weather. 25 members enjoyed the social element of the evening at the outside dining/drinking area at The Sydney Arms in Old Perry Street, Chislehurst. Five teams took part in the DF Hunt. Unusually the team finding the hidden transmitter in the quickest time was the non-member team of Colin and Rosie Merry (G4CDM and G8YDB). Ewan, who organised the event presented the ‘Tally Ho!’ trophy. The results were as follows:
- Construction Evening 16th May
Two club construction projects were organised this year by Dav Walters, M0WDV. More details in an earlier post but briefly they were the Rooster QRP 40m CW transceiver from Kanga Products, and an Arduino Morse keyer compatible with Winkey. The transceiver was the easier to construct of the two projects. The keyer presented difficulties to some members. To assist members with both builds, we held a construction evening at a recent club meeting and here are some pictures from the evening. It was especially good to see some of our newly licensed members getting to grips with home construction.

Anyone who’s read the book The Cray Valley Years, written by the society’s president Bob Treacher, will know that the history of Cray Valley Radio Society from its inception in 1946 is rich and varied. Bob has made no secret of the fact that a considerable amount of source material for his book from 1962 onwards was from old copies of the club’s newsletter, QUA. Of course, in the days before QUA was sent to members digitally starting from the turn of the century, it was a published in hardcopy. In the early days QUA was on foolscap paper, and…

On the Sunday 24th September, Cray Valley Radio Society operated the special event station GB2CM at Crossness to celebrate Railways On The Air (ROTA). This year, ROTA coincided with a steaming day at Crossness when the Prince Consort Engine was in steam. The engine is the largest working rotary beam engine in the country. See https://www.crossness.org.uk/ GB2CM operated next to the engine shed at Crossness and the station was on the air from about 10am until Crossness closed at 4pm. The last time Cray Valley operated at Crossness as part of ROTA was in 2019, using the callsign GB2RAR. RAR stands…

- Summer BBQ 2023
With a dodgy looking weather forecast of high winds and rain showers, the organisers were constantly looking at various weather apps in the run-up to the Saturday barbeque. Could they safely erect the club marquee, would the barbeque grill need to be inside, would rainwear be the order of the day? On the day, the wind wasn’t too much of an issue. The marquee was erected but it was tied off to the fence in several places to prevent any nasty surprises. The barbeque grill was moved inside and comprehensively cleaned. Kieran G8CHB had once again organised the event, with…

- Summer 2023 Radio DF Hunt
In June 2023, over 20 Cray Valley club members attended Radio Direction Finding Hunt, using the Sydney Arms Pub as a base. Six teams entered the competition, which took place on the neighbouring Scadbury Park nature reserve. Three “fox” transmitters were hidden in the park for club members to locate using radio DF techniques. A slight complication to the exercise was a club net in Essex, which popped up on the frequency of transmitter two. The three transmitter frequencies were chosen in the top part of the 144MHz band where there usually isn’t much activity. The club net kindly agreed…

In May 2023, a small team of daring adventurers including club member Nobby G0VJG set off for the tiny island of Rockall, more than 200 nautical miles off the West coast of Scotland and the nearest civilization. Nobby and Emil DL8JJ operated from Rockall from 31 May until 2 June. Rockall is the rarest IOTA in Europe, and the team operated two stations using both CW and SSB modes. This was a once-in-a-lifetime DXpedition. Nobby and Emil left Rockall after a successful few days of operating, leaving only Cam (who was not a ham) alone on the island. Cam’s plan was…

PT20 Pocket Morse Tutor This year, 32 club members participated in the club construction project to build the PT20 Pocket Morse Tutor from Kanga Products. The PT20 Morse Tutor can play 5-character sequences of random letters, numbers, prosigns or a mixture of those at whatever speed the user is comfortable with. It also has modes for callsigns and contest exchanges. It’s a fairly simple kit to build, requiring only basic soldering skills, and it has no surface-mount components or awkward little toroids to wind.

The Monach Islands, also known as Heisker, are an island group west of North Uist in the Outer Hebrides of Scotland. The islands are not to be confused with Hyskeir in the Inner Hebrides, or Haskeir which is also off North Uist and visible from the group. Wikipedia tells us that the main islands of Ceann Ear (once home to a nunnery), and Ceann Iar, the most westerly of the three main Monach Islands and Shivinish (Sibhinis) are all linked at low tide. The islands of the group tend to be low-lying, sandy and subject to intense coastal erosion. Shillay…

This year, ROTA coincided with a steaming day at Crossness when the Prince Consort Engine was in steam. The engine is the largest working rotary beam engine in the country. See https://www.crossness.org.uk/ GB2CM operated next to the engine shed at Crossness and the station was on the air from about 10am until Crossness closed at 4pm. The last time Cray Valley operated at Crossness as part of ROTA was in 2019, using the callsign GB2RAR. RAR stands… Read more: GB2CM Railways On The Air 2023
With a dodgy looking weather forecast of high winds and rain showers, the organisers were constantly looking at various weather apps in the run-up to the Saturday barbeque. Could they safely erect the club marquee, would the barbeque grill need to be inside, would rainwear be the order of the day? On the day, the wind wasn’t too much of an issue. The marquee was erected but it was tied off to the fence in several places to prevent any nasty surprises. The barbeque grill was moved inside and comprehensively cleaned. Kieran G8CHB had once again organised the event, with… Read more: Summer BBQ 2023
In June 2023, over 20 Cray Valley club members attended Radio Direction Finding Hunt, using the Sydney Arms Pub as a base. Six teams entered the competition, which took place on the neighbouring Scadbury Park nature reserve. Three “fox” transmitters were hidden in the park for club members to locate using radio DF techniques. A slight complication to the exercise was a club net in Essex, which popped up on the frequency of transmitter two. The three transmitter frequencies were chosen in the top part of the 144MHz band where there usually isn’t much activity. The club net kindly agreed… Read more: Summer 2023 Radio DF Hunt
In May 2023, a small team of daring adventurers including club member Nobby G0VJG set off for the tiny island of Rockall, more than 200 nautical miles off the West coast of Scotland and the nearest civilization. Nobby and Emil DL8JJ operated from Rockall from 31 May until 2 June. Rockall is the rarest IOTA in Europe, and the team operated two stations using both CW and SSB modes. This was a once-in-a-lifetime DXpedition. Nobby and Emil left Rockall after a successful few days of operating, leaving only Cam (who was not a ham) alone on the island. Cam’s plan was… Read more: Rockall DXpedition
Celebrating the coronation of King Charles III and Queen Camilla Cray Valley Radio Society organised a flagship amateur radio station GB23C located in the Monument Gardens of the Old Royal Naval College in Greenwich. The site for the station was next to the historic sailing ship ‘Cutty Sark’. Club members operated the station around-the-clock once the radios, antennas an exhibition areas had been set up at 6pm on Wednesday 3 May. The stations were on the air through to the early hours of the morning of Tuesday 9 May. Operation was from a marquee with two towers supporting antennas for… Read more: GB23C Special Event Station
PT20 Pocket Morse Tutor This year, 32 club members participated in the club construction project to build the PT20 Pocket Morse Tutor from Kanga Products. The PT20 Morse Tutor can play 5-character sequences of random letters, numbers, prosigns or a mixture of those at whatever speed the user is comfortable with. It also has modes for callsigns and contest exchanges. It’s a fairly simple kit to build, requiring only basic soldering skills, and it has no surface-mount components or awkward little toroids to wind.
The club hosted the GB8KW special event station on 7th and 8th of January 2023 at the Cray Valley Club Shack. This annual event marks the anniversary of the founding of KW Electronics in the mid 1950s. Guy G0UKN brought together a range of vintage AM and SSB stations to celebrate the iconic KW Electronic brand of radio equipment made just down the road in Dartford until the mid-70s. Guy was assisted by Steve G3ZPS, who used to visit the KW works as a teenage ham and has also built up a collection of vintage gear. Past years have seen the… Read more: KW Weekend 2023
GB70 was a series of amateur radio special event stations, celebrating Her Majesty Queen Elizabeth’s Platinum Jubilee. Cray Valley Radio Society worked with Burnham Beeches Radio Club to operate the GB70E station from Windsor Home Park on 2-6 June. Other RSGB affiliated clubs activated six other similar special event stations in other parts of the United Kingdom during the same period. The special event stations were located in all four nations of the UK (England, Wales, Scotland, Northern Ireland), and the Crown Dependencies (Jersey, Guernsey, Isle of Man). Each operated using their own, special callsign ending in the letter (or “Regional Secondary… Read more: GB70E Celebrating Queen Elizabeth’s platinum jubilee
(tr)uSDX all-mode 5-band QRP HF Transceiver In 2022, 30 club members participated in the club construction project to build the (tr)uSDX transceiver, designed by Manuel DL2MAN and Guido PE1NNZ. The kit comprises all the components and circuit boards. The boards are already populated with all surface-mount components, so members are only soldering through-hole components. The case is 3D printed. The (tr)uSDX is a great feat of engineering for the price and size, and features FM, AM, SSB and CW modes on 20m, 30m, 40m, 60m and 80m. It even supports CAT control (Kenwood TS480 emulation) and can be used for… Read more: Club construction project 2022
After the enforced scaling-back of GB8KW in 2021, the GB8KW special event was again run from the Cray Valley shack on 8-9 January 2022. Eight fully operational stations were on display, all using different KW models including all versions of the KW2000 (mk1 through to E). Most on-air activity was with the KW2000B+KW1000 combo, but the KW Atlanta and KW1000 was also used on 20 metres. There was a comprehensive display of the history of KW, together with some artifacts including a repaired Kokusai mechanical filter. Both Guy G0UKN and Steve G3ZPS have extensive experience of restoring KW equipment to… Read more: KW Weekend 2022

The Monach Islands, also known as Heisker, are an island group west of North Uist in the Outer Hebrides of Scotland. The islands are not to be confused with Hyskeir in the Inner Hebrides, or Haskeir which is also off North Uist and visible from the group. Wikipedia tells us that the main islands of Ceann Ear (once home to a nunnery), and Ceann Iar, the most westerly of the three main Monach Islands and Shivinish (Sibhinis) are all linked at low tide. The islands of the group tend to be low-lying, sandy and subject to intense coastal erosion. Shillay… Read more: DXpedition to the Monach Islands
2O12L – Two Oscar One Two London – was the callsign of the London Flagship Amateur Radio Station celebrating the 2012 Olympic Games and Paralympic Games. This unique amateur radio special event radio station was organised by Cray Valley RS and operated from the Royal Greenwich District Scouts Activity Centre in New Eltham, south-east London between 25th July and 9th September 2012.

We exceeded our QSO target,… Read more: 2O12L London Olympics
Trafalgar 200th Anniversary Celebration Following the successful large-scale special event stations M2000A and GB50, the Cray Valley RS team ran a third large event from 17 to 24 October 2005 to mark the bicentenary of the Battle of Trafalgar. A single antenna mast was placed on the front lawn of the National Maritime Museum in Greenwich, and supported antennas for 80m through to 70cm. It was ‘dressed overall’ with signal flags in the pattern that would be used by a Navy ship in harbour on a special occasion. Meticulous planning with the Museum authorities was necessary in order to get… Read more: GB200T – Trafalgar
