I think I am from the last of my generation that made crystal sets with their dad. I can still remember the magic of hearing The Beatles played on Wonderful Radio London through ex-BBC high impedance headphones. The rest of the set being just a coil wound on a toilet roll, a germanium crystal diode, a variable tuning capacitor, and a 1000pf decoupling capacitor, of course, there was the aerial, a 50ft length of wire out of the bedroom window to a tree and the earth connection to the cold water pipe. No batteries, no power….FREE radio!!!!.
Just fantastic.
1967 came and Harold Wilson closed down the offshore pirate stations. I remember being in the sixth form centre at Heath Clark Grammar School in Waddon, and seeing a girl crying at the lost of Big L. Then the talk around all the Croydon schools was about Radio Helen on 197 metres. Land based pirate radio station. I had to be a part of this.
Having played around with crystal sets, people thought I could build a transmitter. Luckily for us budding radio enthusiasts, Croydon had several radio junk shops where we could get cheap parts. Sadly, all have now gone, the largest of which was an emporium called Huggett’s, which was run by Tom Huggett and his wife. She was always amused that I kept my money in my sock because my jeans or bright red loons were so tight, I could not use my pockets.
My first attempt to build a medium wave transmitter resulted in a burnt hole in my bedroom carpet. I had copied a design of a marine transmitter but had failed to appreciate that it was designed to run off a DC supply on a boat and not the AC mains…..no thought of rectification and smoothing, result; big bang.
Before I had success with my own build, I met up with Andy Mac the technical brains behind Radio Helen.
Through contacts, girls at my school who had been on dates with boys from other schools, I eventually met up with guys from Selhurst Grammar School and the Norbury area who were involved with the Radio Helen network. By this time, the Helen network was starting to fall apart. The principle was fine, in that each station transmitted for half an hour and then pasted on to the next. The reality was that it often ended up in chaos for many reasons; technical breakdowns, one station not hearing another, etc, etc.
I teamed up with two Daves from Norbury, one of whom knew Andy well and he gave us what was the largest of the Radio Helen transmitters and we hit 197 metres as Radio Active. Andy subsequently went to study engineering at Hatfield and I believe became a television transmitter engineer. Does anybody know of his whereabouts these days? If you do, pleae email us.
