Craig 4201

[Greg T]

Does anyone know how to increase the modulation on a Craig 4201? I can find schematics, tune up instructions, Mic wiring, but no modulation increase.

If you can trust Sam's (CB-99), R192 is the modulation adjustment and R191 will adjust the modulation meter.

There's also a pdf out there that says cut CR118 and CR119. I'd suggest just desoldering in case it doesn't work. Link thingee: https://preview.tinyurl.com/4reeud4p

Sorry, don't actually have a 4201 to confirm any of this with. Use at own risk, buyer beware, blah blah blah...

Thank you very much, guys. Much appreciated. I have no idea why this stuff doesn't show up in the search engines.

I cheated a bit. Looked it up in the Sam's index and then checked the relevant book for transmitter alignment. Search engine won't do that.

Would get in the way of the ads.

Appreciated. As I checked out the links I remembered that I have all of the Masters publications stuffed in a closet from back in the day when I was "golden screwdrivering" for the locals.
