For ease of use I've omitted many of the prefix/suffix letters (E.G. the IC-706, IC-706MKII & IC-706 MKII G are simply listed as IC-706 and the IC-E2820 / IC-2820H as IC-2820) except where there is a major difference. Any minor connection differences will be noted on the relevant page.

Mobile, Portable and Base radios:

Handheld radios:

You may well see the same microphone listed as an option for models with differing pinouts. This is usually due to the voltage differences (3.2, 3.5, 5 volts). Mics that don't require power or have been designed to work between the lowest and highest voltages will be able to be used on all the range. I have seperated the radios according to the differences for clarity.
