Yaesu Md 100 Schematic Portable

Kenwood uses a very similar 8-pin layout, but the Pin assignments differ. You will need to cross-reference the MD-100 schematic to map Yaesu’s Pin 5 (Mic) to Kenwood's Pin 1, and Yaesu's Pin 3 (PTT) to Kenwood's Pin 2.

With a printed schematic and a multimeter, you can fix 90% of MD-100 issues. Yaesu Md 100 Schematic
