Hi,

Does anyone know of a good book or other source of RF (100kHz - 1MHz) LC oscillator designs? I'm looking for something fairly complete (i.e. with typical component values and transistor types) as I don't have a huge amount of time (or money!)to spend on this. It's to form part of some demonstration equipment for talks to schools etc in connection with voluntary work as a STEM Ambassador.

Probably looking at something like one-transistor oscillators, the key point is that they must be tuneable using a single capacitor.

Any help greatly appreciated!

Many thanks,

Andy

Doh! I should have thought of that! I'll have a look.


Actually, thinking about that I may have a copy somewhere in my loft - I took the RAE many years ago but never did anything with it.


I've been meaning to make contact with them for some time for many reasons, I know a couple of members quite well (I'll be playing guitar with one of them tonight!) but both are operators rather than into nitty-gritty electronics people. Other than that it is the usual question of finding spare time!



Exactly my thoughts. I have been looking around to see if anyone makes cheap superhet kit-built radios that I could modify, but couldn't find any. Then decided it was about time I stopped being scared of building RF circuits and had a go myself...


Many thanks. If I don't get anywhere with the above I'll take you up on that.

You're welcome to send some down here (Devon/Cornwall border)! We've heard traveller's tales about this white stuff that falls from the sky but it would be nice to see some for real :-)
