Another memory of TA28, Rod: I recall that somebody on the course had
a clever simple circuit for a one transistor FM TX. ISTR that it might
even have been you?
I remember such a thing from school in the 1970s; it involved a fairly
crude one-transistor oscillator, that possibly even worked by parasitic
pickup, i. e. shouldn't have worked at all. (2N2219A was it?) Ours had a
second transistor - BC108 possibly - but that was just to amplify a
microphone input. I do remember it involved a coil that was three or
four turns round a Biro, and a 3 or 4 inch aerial. IIRR, there were only
about two or three other components - maybe two R and a C? I know kits
were available - especially in US - to make such things, on about a
squinch of PCB.
