? about a modulation mod

#53073

Post by bombardair »

I found a modulation mod for a small radio shack radio. It is listed as r67. I was wondering if it was just a matter of clipping the resister or do I have to change the value? Or do I add a variable resister? Or can I add a potentiometer to the radio in line from the resister? I am new to this tech work and it was a freebie! I figured this was a good starting point!
Thanks for your time , Dave

Depending on the specific model, there is usually a POT already on the board for adjusting the modulation level. If not, I'd recommend experimenting with higher resistor values. Clipping will certainly get more modulation, but will also lead to alot of problems. Visit [Please login or register to view this link] for a discussion of some of the problems that can arise.

If you go to CBtricks.com they might have a listing for the mods on your radio. On the cobra's we clip a Diode.
