    Thanks for sharing.

    My first build was from the Ladybird book “Making a Transistor Radio” by the wonderful George Dobbs. This started as a crystal set, then was built upon as you worked through the book.

    Kind regards,



    Phil

    My pleasure, OM Phil.

    A similar book started me off in the mid-nineteen sixtees.

    Recently nostalgia took over and I delved deeper!

    I recently joined a FaceBook group called "Crystal Set Radio Group", pretty good, with lots of circuits, restorations & home brew...

    My first tranceiver was something similar, though I used a Gunn diode and a very simple circuit that acted as both modulator and demod.
    The parts were salvaged from an automatic door opening system that used 10 to 11 GHz.

    Hi OM Robert,

    That's at the other end of the spectrum!

    I used to get into serious trouble with my mother, because I used my sisters wooden toy pastry boards and drilled holes in them. The radios worked until I had to give the boards back.
    I'm leaving now to go find myself....if I arrive before I get back, please ask me to wait!
