G5HF's June Event - GB5HF

4th July 2007Minor corrections. Added Murray's photographs.   Minor changes.   Added the report & pictures.


CARS President, Harry Heap, G5HF celebrates his 90th Birthday this year.

During WWII Harry was one of a select band of Radio Amateurs who were members of the very secret Voluntary Inceptors who had to listen to enemy radio traffic and send what they had received to Bletchley Park, where, if appropriate it was decoded.   See July issue of RadCom, Page 11.

Harry's Son, Peter thought that an event should be staged to celebrate Harry's Birthday but in true military fashion, Harry should not know about it! This proved more difficult than was expected.

Since Harry is often on the air, nothing could be discussed which he could evesdrop. A letter was sent to Pat Hawker, G3VA who was also a Voluntary Interceptor who contacted other members by letter and a Schedule was arranged for the day in question. Ofcom were approached and released GB5HF because we could not use G5HF as he would have to be present!

Tony Gilbey, G4YTG designed and manufactured a 16 foot high Vertical aerial for the 80 Metre Band and this was tested off-site.

A major problem has been encountered at MASC in the past whereby any RF signal stronger than 1 Watts has triggered the High Sound Alarm & disconnected the power to the room/building!  

The Loud Music Alarm Box

The Loud Music Alarm Box screwed to the ceiling of the MASC room.

To prevent this happening running 100 Watts the Vertical was to be located in the middle of what was the Football Pitch. The whole site has been sold to a developer who is going to build a new Club House, demolish the existing & built 139 houses on the site.

Imagine our horror when CARS Members were putting up the Vertical in the centre of the field in long grass when a huge John Dere tractor with a flail appeared to cut it. However the grass cutting team were very accommodating.   We had to leave the field (cannot get nearer than 24 feet from an operating Flail) while they cut a large area to enable us to erect the aerial - phewww! Having cut the centre we were allowed back & erected the Aerial.

Once the aerial was connected a test tranmission was made with Bob, G3ASE, one of Pat, G3VA's contacts.   Conditions were not good but a 4 by 7 contact was made, we were in business and the TX was shut down to await the arrival of Harry's Family, CARS Members & the general public.

Unfortunately a piece of MASC kitchen equipment was switched on which provided +100dB induced QRM such that QSOs were totally impossible so the plug had to be pulled earlier than anticapted. However a good number of contacts were made & a special QSL Card will be produced to commemorate the Event.

A few minutes after the Aerial was taken down (early) and this photograph was taken a storm swept the area - so the QRM
had its advantage after all.

A great team effort - thanks to everyone - send your QSL cards, preferably via the RSGB Bureau - or direct - see CARS Web Site Home Page for directions.
