A huge thank-you to David T (
David G4EBT) for the beautifully-constructed and laid-out FM-AM converter.
Not only did it arrive almost instantly, but the way it's put together is to professional standards (better, in fact, than commercial products as it uses "proper" solder), and it's finished off with an informative leaflet describing its operation etc. Truely plug-and-play too, apart from the PIC.
I'm very impressed, and very grateful.
THANK YOU, David
