Powered by +5V from the radio, the circuit uses μPC4572C op-amps for "High Emphasis" and "Low Cut" filtering. Controls:
The schematic for an (designed for the FT-100/FT-817/FT-857 series with an 8-pin round plug) is different from the MD-100C (designed for Icoms with a modular plug). Ensure you are searching for the exact suffix.
The MD-100 circuit is centered around an internal preamp and filter board. This board allows operators to tailor their audio profile directly from the microphone base.
This is a resistor ladder network.
