Monday 12th June - DF Hunt - Derek Hills G6MFM DF Trophy

It was a glorious sunny evening and 9 members turned out to support the annual Derek Hills G6MFM DF Trophy. Discretely hidden in the woods at the end of Nork Park, Bansteadwere three 2 metre AM transmitters each transmitting their own individual ident to the hunter. With the foxes carefully laid out by Denis M0NDJ, our hounds set off to track down the foxes. Waiting for the hounds to return seemed like forever. Some returned not having found a fox and others returned having found all three. It was a great evening and my thanks go to Denis M0NDJ for organising the event and for supplying the equipment.

(Ed... Thanks Stuart for the article. I still can't get your photos to turn around. Very odd!)

CATS Radio Activity Meeting – July Meeting

Having enjoyed an extended recent spell of good weather, it was suggested that for the July club night, we go up to Epsom Downs for a bit of operating. Terry G4CDY was the mastermind behind this idea and suggested we all meet in the Hut Café car park at Tattenham Corner.

Now, we all know that if it can go wrong, it will go wrong. Some may call it Murphy’s Law and other’s will call it Sods Law.

I duly arrived arrived at the car park, the one with the café at the suggested time, waited a

bit and set up my Tarheel aerial. I waited and waited and at about 7.15 Andy G8JAC turned up in his Austin Champ. Where were the others? Not far away it seemed. The majority of the club membership had set up in the car park on the opposite side of the main road to where I was, in a car park with no café. So there we had it, two camps. In terms of contacts, I have to say that it wasn’t a terribly successful evening. We had tried to set up a sked with Flo G4DMA, but conditions didn’t allow us to make it. I went to school with Flo and he is KL7X living the life in Alaska and it would have been great if we could have made the contact. The only contact I had was on HF and that was with Terry G4CDY who was 200 yards away.

We did manage to make a contact with Flo via mobile phone from the Woolpack. Attached is a photo I took of CDY, JAC and JXN and return photo of Flo.

I don’t know who else turned up at CDY’s car park. I saw Biton and I think he posted a video (Biton's Youtube Video was uploaded to Youtube and can be viewed with this link https://youtu.be/TsXml040JiY )

Sutton & Cheam Radio Society Trip to Bletchley Park - DebriefAttendees: Stuart G6CJR, Alan G8UHN, Vince G1HRD plus Doug, Vince’s son, Adam G7CRQ & Steve G7SYO

Some years ago when I worked for BT, I recall going to Bletchley Park on a course. I can’t remember what the course was all about and at the time, I wasn’t aware of the significanceof Bletchley Park.

Since then, I have learned more about Bletchley Park, and the talented people that workedthere, all of whom played such an important role in bringing the war to a swift end. Bletchley Park was the wartime home to the codebreakers. It was a factory for code breaking and it is said that if it wasn’t for the mathematicians, codebreakers and everyone that worked at Bletchley Park, the war would have been extended by at least 3 years. The work of the codebreakers were unimaginable.

Later on in the afternoon, we all took a trip outside of the camp to the National Museum of Computing where Alan G8UHN used his charm on the young lady in reception to get us a vastly reduced entry into the museum. The stuff being exhibited is something else. So archaic by modern standards. http://www.tnmoc.org/
