The M-70 uses a directional condenser microphone that is specially tuned to the frequency response to create clear and crisp audio for radio communication. The PTT uses three pneumatic cylinder tubes similar to the M-1 reference microphone to provide solid and smooth prolonged operation. A simple one-touch PTT key lock button is located just above the PTT key for those long chewed rags.
The built-in Low-Cut filter allows you to shape the low frequency response (cut at 340 Hz, -6dB / octave). ON / OFF is selectable via a slide switch located at the bottom of the microphone. An isolation transformer is integrated into the printed circuit board to improve audio quality. The M-70 is compatible with all YAESU HF transceivers equipped with an 8-pin round microphone connector or an 8-pin modular microphone connector. We believe this microphone will have a positive impact on your YAESU HF transceiver business.
