Description
External BFO V2.1 SMD version
I recently restored a Grundig Satellit 2100, which turned out really well, and which can be viewed on my YouTube Channel, Electronics Old and New. I mentioned then that I’d think about building an external BFO (beat frequency oscillator) to permit me to listen to Amateur Band SSB comms. This is my attempt at it, using PCB’s I ordered from PCBWay, and using only through-hole components.
The build video can be seen at:
