Sixty years ago this month, the July 1960 issue of Electronics World carried the plans for this CB converter. The magazine noted that inexpensive transceivers were available with superregenerative receivers, and that those worked well at first to get people on the air at a low price. But as the band became more and more popular, the lack of selectivity posed a problem, and a superheterodyne was becoming necessary.
This circuit used a single 6EZ8 triple triode, and would use a standard AM radio tuned to 1500 kHz as the IF stage. It circuit could also be tuned to cover any 400 KHz segment of the 10 meter band.
