At its core, the MD-100 is a dynamic microphone. Unlike condenser microphones that require external bias voltage, a dynamic microphone utilizes a diaphragm attached to a coil suspended in a magnetic field. When sound waves strike the diaphragm, the coil moves, generating an electrical signal. The schematic of the MD-100 reflects this fundamental simplicity. The primary audio path is a straightforward run from the microphone element through the wiring harness to the radio. However, the genius of the MD-100 schematic lies not in the audio path itself, but in the support circuitry that surrounds it. Yaesu Md 100 Schematic

If you are trying to wire this mic to an Icom or Kenwood rig, you cannot simply cross-wire the pins. You must account for voltage differences and the fact that Icom transceivers expect a high-impedance electret element rather than the MD-100's low-impedance dynamic element.
