GEORGE HERIOT'S SCHOOL RADIO CLUB
George Heriot's School in central Edinburgh in 1969.
1923 – Receiving apparatus constructed and working; aerial erected at the school, Castle in background. Reported in The Wireless World and Radio Review, Sep 26, 1923 p. 876).
1953-54 - Heriot’s Radio Club re-founded. A founder member was Norman D H Murphy (SK 2015).
First project was a valve audio amplifier with pair of tetrode valves in push-pull.
"For myself, moving back in time just a little, my first interest in wireless and electromagnetic waves and all such things came in 1952 or thereabout when I found a book in the Heriot's school library – probably printed thirty years earlier – describing the wonders of very early wireless techniques. This book explained the functions of crystal sets, and of such long-forgotten devices as the Self-Restoring Coherer, which was, as far as I could gather, a very early form of radio signal detector, probably invented before I was born and abandoned not long afterwards. Nonetheless I was fascinated. The whole concept of radio - or wireless, as we called it in Britain in those days - appealed to me.
I think it was in 1953 or early 1954 that Heriot's school started its very first Radio Club for after-school enthusiasts. I was a founder member. I think our first project, and the only one we undertook that year, was to build an amplifier. Needless to say, it was a valve-based device of which I can remember little, except that the output stage was probably a pair of tetrode valves working in Class B push-pull. (I ask you to forgive these minor technicalities; they are important to the historical progression of this note.) I left school before the amplifier was actually finished."
1954-55 - Sorry to lose physics teacher Mr Jim Jardine (who moved to George Watson’s College); replaced by Mr Barr.
Exhibition including oscilloscope (I. Reid); cycle radio (J. Telfer); extensive survey of valves, past & present; many items of ex-government radio equipment. Film on valve manufacture.
1961-65 - Club met on Thursdays at 3:10pm in the radio workshop of the Physics Department. Talks by club members on R/C models, “amateur broadcasting”, transistor radios & television. Construction projects: oscilloscopes, guitar amplifiers, electronic locks (clocks?), transistor tester. Mr Alistair Johnston (Physics) left (1965) and was replaced by Mr. Borthwick. Secretary, Thomas J. Harrison, 5D.
1970 – Club seems to have stopped for some years around 1970.
~1975 – Club was re-formed by Chris Armistead, Gordon Mathew, Iain Gillespie, David Cockerill, supported by Mr Bob Neil, Head of Physics.
~1977 - GM4FFI club callsign issued.
1977 – Headmaster, Mr Alan McDonald, agreed to the purchase of a Yaesu FT101E transceiver. Also using Pye Cambridge or Vanguard for 2m VHF.
Gordon Mathew GM4MOQ, Leonard Rollo GM4HFM (SK) operating the new Yaesu FT-101E.
L-R: Andrew Johnson, Lawrence Rollo?, Leonard Rollo GM4HFM (SK), Gordon Mathew GM8MOQ.
1979 – Mr Balfour made several contacts with UK and Europe using the club’s transceiver.
1979 - Visit to Radio Forth - see photo above.
1985 - Holder and club supervisor was GM4GMC - J. Balfour.
1994 - Neither GM4FFI nor GM4GMC still listed in Callbook. Assume club had folded.
