Hearing Stanley's comment in another thread about someone he knew at Lancaster Uni that made a radio with a bucket and a coat hanger has got me going.
I'm going to need one or two bits and pieces to make this work.
Some wire, a safety pin, a pencil, some kind of earpiece and a razor blade. That should just about do it.
An appeal to all the locals, probably the blokes. Ideally I need one of those old fashioned single sided razor blades (preferably blued), although this could be sorted if its not. A later generation double sided Blue Gillette blade would probably do at a pinch but the single sided ones have recesses in the right place for fixing. Can anyone help?
We shall make music or speech (or both) out of the ether once we get the kit together.
Ian

Problem about sheds is that they have to take the back seat from time to time.

We need people like you to keep it alive and going Ian. Amateurs contribute a lot to technical and scientific advance and they often see a broader picture than the professionals, as shown in astronomy and environmental and wildlife studies.

Thanks for that Peter. You are correct in your evaluation of the contribution made by the amateur radio fraternity over the years.
Way back in the early 1930's the VHF bands (shall we say above 50MHz) were considered unuseable for communication and so were made available to the licenced amateurs to use. Amateurs developed advances in VHF circuit design leading to more stable communication on these bands. Througout the 1930's and duriing the build up to war these developments led to reliable ground to air systems for use in fighters and air to air communication systems.
Contributions also to the development of radar and long range LF communication to submbarines, direction finding, aircraft navigation and tank communication systems.
Hundreds of amateurs were recruited to swell the ranks of "the backroom boys" during The Second World War. Many joined as radio operators, on the other side of the coin, many ex military trained radio operators became licenced amateurs after the war. The skills they learned were then filtered down to others. (I was taught morse by two ex RAF radio operators).
The list of innovative developments that amateurs have had a hand in is actualy quite large. Some of the stuff that was originally experimented with has gone global such as the techonology behind mobile phones and many of the packet based protocols used by email and the internet. I am not claiming that all of these are a direct and sole development of some bloke on his kitchen table or in his shack or shed, but radio amateurs have certainly played their part in many areas of communication that everyone benefits from and we all now take for granted.
The eroding away, by whatever means of the bands agreed by International Treaty and allocated to radio amateurs would be a travesty, and in the long run, would probably be detrimental to further advancements in many areas of communication.

Ian, I haven't forgotten that transformer! It has not raised its head over the parapet yet, if it does you will hear immediately! I agree with everythning you say about innovation stemming from amateurs. I suspect it is still happening but ignored by media. Shed Rules, OK?
