Replacement Electret Element Kits
for Yaesu MD200, MD100, MD1, MH31

by Bob W2ENY


I've been experimenting with MANY headsets and mic elements over the last years. This element far exceeds mic specs for optimum use with todays radio technology. I originally designed the application as a direct solder in replacement that brought Hi-Fi audio and new life to my old D-104 and I now have it for the Yaesu models MD200, MD100, MD1 and MH31 (separate kits for each model).

It's a 15-30 minute job to add it in and it works great!! Features great sound with full range audio, 50 Hz - 16 kHz wide range FLAT Response - Natural Sound Finally, a great alternative to the HC-Contest Sound element offered by celebrity hams!

This is a wide range electret element that is powered by and works with Yaesu radios having the 8 pin mic connector that has voltage - 450, 817, 847, 857, 897, 920, 950, 2000, 2000D, 1000MP, 1000MP Mk V, Field, FTDX1200, FTDX3000, FTDX5000, FTDX9000...

THIS WILL NOT WORK ON THE FT-757, 767, 840, 990, FT1000 or FT1000D radios as there's no voltage on pin 2 of the radio mike connector.

Each kit comes with the mic element, bias resistor and color instructions for the model you selected below..
