  • GB2RE Jamboree On The Air 2023
    In October 2023, Jamboree On the Air (JOTA) took place at Severndoog Castle, organised by the Scouts and Cray Valley Radio Society. CVRS ran four bases this year. Together with the normal HF, DF hunt and Morse-code bases, the club also ran Amateur TV for the first time. All proved very popular with the most popular, and the one that drew the most comments, being the Morse sessions. The feedback received again singled out the Morse code sessions for particular praise both in terms of how the youngsters took to it but also the attention to detail from the instructors. … Read more
  • GB2CM Railways On The Air 2023
    On the Sunday 24th September, Cray Valley Radio Society operated the special event station GB2CM at Crossness to celebrate Railways On The Air (ROTA).

  • 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 … Read more
  • 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 … Read more
  • Rockall DXpedition
    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

  • Club Construction Project 2023
    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.

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

  • Club construction project 2022
    (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

Both Guy G0UKN and Steve G3ZPS have extensive experience of restoring KW equipment to … Read more

  • DXpedition to the Monach Islands
    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

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
