I had transferred my kit to a circuit board I etched using the Radio Shack circuit board etching kit.
I do not have the kit anymore, but I still have two copies of the owners manual that came with the kit.
Those crystal type microphones were cheaply made, I had to connect a stereo to mono amplifier to the + and – inputs of the kit to get audio into it.
I know I had those two transistors oriented correctly, so I do not think it was that.
With the included antenna wire it didn’t go very far, I used a 9 volt AC to DC adapter to keep mine going. That large coil on the plastic frame was kind of flimsy though.
I liked how the included paperwork explained how real AM radio stations operated compared to the kit version. I seem to have lost that paperwork though.
