[Hvde over on Hackster.io] has put together an amazingly well done CB radio to 6m conversion that allows him to operate AM USB and LSB within the 6m ham radio band.

The process involved replacing the VCO with one generated using an arduino and even adding a display to the old CB radio.

Hvde has done a lot of work and has a well detailed schematic which includes his modifications that made everything work. You’ll find a video of his efforts below gloriously listening into the 6m SSB spectrum.
