This section contains diagrams for the microphone connections on many of the common CB radios, as well as some popular Amateur radios.
The diagrams show the plugs as viewed from the inside, as you would see it while soldering.

As the database is large, and a full list of radios may be a large download and a long list to search, please start by specifying a radio make or model below. You will then be presented with a shortlist of radios with a make or model matching your search word - and a list of microphones.
