If any are interested I like to start a thread on understanding how CB radios work. I have picked up some free time now and it may be something to help those that want to learn. There are a lot of folks here full of technical knowledge and I think this would be a good tread to help others that want to know learn and understand what is going on in these little set’s. I see so many folks trying to troubleshoot radios and do not even know where on the board to find the problem let alone on the schematic.
What I like to do is start with a chassis like the cobra 29.
Post a schematic with the various stages marked.
Post a description of components and what they are. For instance;
TR 1 (RF AMP),
IC 3 (TX MIXER)
Ecx.
Just to give the guys that want to learn a bit of a heads up.
Then in the end discuss how to make your own test equipment like using the 29 as a signal generator
I have uploaded the modified schematic. This is not my work. It was given to me and I updated it.
