Convert 40 Channel CB to 6M , change 1 crystal and retune !

Have you tried this and if so what modle did you use ?



There was an article about doing this in 73 about twenty years ago,
when conversions of PLL CB sets were alll the rage. It counted on
the injection frequency being on the high side, so the image frequency
was in the six meter band. I can't remember whether it worked out
directly, or if one had to fiddle with something.

Pete's right, the front end would have to be adjusted.

It's an interesting scheme, but oddly while it would require less
construction, it may be more daunting for a beginner to do such
modifications than for that beginner to build a converter as someone
suggested. You don't have to worry about tracking down a schematic
for the CB set, you don't have to worry about finding what's where (or
figure out what needs to be done when likely there aren't specific
instructions for the set in hand), and don't have to worry about working
in the confined spaces. Building a converter from scratch means you
can wait till you have a full schematic for parts that you can get,
and you can construct it in a fashion where there is plenty of space,
though of course it would need to be built in a small area for proper
performance.
