YAESU M-90D

The new Yaesu M-90D dynamic table microphone is a relative of the recently introduced M-70. The design resembles the M-100.

The M-90D utilizes a directional dynamic microphone element which is specially tuned the frequency response to create clear and crisp audio for radio communication. Built-in Low-Cut filter allows to shape the low frequency response (cut off at 340Hz, -6dB/octave). An isolation transformer is integrated in the circuit board to enhance the audio quality.

The PTT uses three Air-Cylinder tubes similar to the Reference Microphone M-1 to provide a solid and smooth extended operation. A simple one-touch PTT keylock button is placed just above the PTT key for those long rag chews. When the key is pressed again the transceiver returns to receive mode again.

The M-90D is compatible with all YAESU HF transceivers equipped with round 8-pin microphone connector or 8-pin modular microphone connector. The RJ45 and 8P sockets in the base of the M-90D are internally bridged 1:1. The supplied microphone cable has RJ45 on one side and an 8-pin round plug on the other. You can therefore use the cable for devices with RJ45 as well as for devices with an 8-pin round microphone plug. Simply reverse the cable.
