I have just purchased a few boxes of vintage radio crystals. Dont know if they work or not. Is there a simple circuit I can use, preferably transistor for now, to go through them all and test to see which are working or not.
The ones I dont use would probably be sold, if I can check if they are working or not.
The ultimate plan was to finally get around to making a micro TX like Trevor's one.
Cheers
Mike
