M-1 The Condenser Microphone Element produces greater frequency response and clear, crisp audio characteristics perfect for being heard on crowd bands and in big DX pile-ups, while the Dynamic Microphone Element delivers the rich low-mid tonalities, favored for local QSOs.  The response of each microphone element may be adjusted independently using the internal Nine (9) Band Graphic Equalizer.  Each element has a separate volume control for independent adjustment of output levels.  The output of each microphone may be selected separately, or they may be combined to produce the most pleasant tonality.  Both the Condenser Element and Dynamic Element in the M-1 utilize the Nine (9) Band Graphic Equalizer (63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz).  Each element’s frequency response is independently adjustable.  Two (2) frequency response memories and a “through” mode are provided for each element, and are easily switchable by one-touch buttons on the microphone base.  The PTT key uses three Air-Cylinder Tubes which afford a smooth and comfortable long keystone.  The contactless magnetic switch ensures long-life and stable operation.  Other included features are; Recording and playback capability (20 seconds), to confirm the audio tonality; Large red TX LED Indicator; Large Graphic Equalizer and Frequency Response Scope LCD Display with anti-reflective coating; Headphone jack; Touch PTT keylock; Built-in low-cut filter to shape the low frequency response; Cannon-type (XLR) output plug connector; and Audio output volume control for headphones.  Two screwdrivers are included to precisely adjust the graphic equalizer and microphone gains. 
M-100 The Condenser Microphone Element produces greater overall frequency response - with clear and crisp audio characteristics - while the Dynamic Microphone Element delivers enhanced low and mid-range frequency response.  A set of one-touch buttons on the microphone base enable the two microphone elements to be used independently or in combinations to create the most favorable sound quality for each person’s unique voice characteristics.  Built-in Low-Cut (cut-off at 340Hz, -6dB/octave) and High-Cut (cut-off  at 2kHz, -6dB/octave) controls shape the low/ high frequency responses enabling changes to be made in the transmitted audio characteristics, according to user’s preference and operating conditions.   The supplied TBC (Treble Boost Cowling) further enhances the voice response attributes in the important 1,000 – 1,500 Hz range, in order to develop a penetrating signal with a condensed and specific texture.  The PTT key actuates three Air-Cylinder Tubes, which afford a smooth and comfortable keystroke – free of a hard “click”.  The incorporation of a magnetic switch ensures long-life and stable operation. The highly visible ON AIR LED Indicator clearly informs the user when the PTT circuit is active. The supplied microphone cable can be used to provide power to the M-100 simply by connecting with compatible YAESU HF transceivers*.  Current YAESU HF radio owners can immediately start using this new microphone as an exciting and valuable addition to their current ham radio operation.  Whether it’s for wider-range audio with more presence or focused energy to cut through the pile-ups, the M-100 is an exceptional station asset.  While the recently released M-1 microphone provides the ultimate flexibility in enhancing each user’s distinctive voice characteristics - utilizing a full-featured Nine Band Graphic Equalizer - we are confident that the carefully selected feature configuration of the new M-100 offers the advantage of combining the two different microphone element characteristics with simplified operation, all at a very attractive price point.
M-70D The M-70 utilizes a directional condenser microphone element which has a prescisely tuned the frequency response to obtain clear and crisp 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.  Built-in Low-Cut filter allows to shaping of the low frequency response (cut off at 340Hz, -6dB/octave). ON/ OFF is selectable by a sliding switch located on the bottom of the microphone.    An isolation transformer is integrated in the circuit board to enhance the audio quality. The M-70 is compatible with all YAESU HF transceivers equipped with round 8-pin microphone connector or 8-pin modular microphone connector.  We believe this Microphone will have a positive impact on your YAESU HF transceivers business.
M-90D The M-90D and M-90MS utilizes a dynamic microphone element that is finely tuned to deliver rich low to mid frequency response desirable for a clear and concise conversation.  Using a windscreen cover and a directional micophone element, the structure of the microphone of the M-90D and M- 90MS is designed to concentrate voice input from the front while reducing ambient noise from the side. Built-in Low-Cut filter creates clear and crisp audio characteristics by shaping the low frequency response (cut off at 340Hz, -6dB/octave).  An isolation transformer is integrated in the circuit board in order to enhance the audio quality. The M-90D and M-90MS* are compatible with all YAESU HF transceivers equipped with the round 8-pin microphone connector or the 8-pin modular microphone connector.  The PTT of the M-90D uses three Air-Cylinder tubes similar to the Reference Microphone M-1. This provides solid and smooth extended operation.  A simple one-touch PTT keylock button is placed directly above the PTT key for those long rag chews.

Uncompromising Receiver Circuit Design Ensures Excellent Performance

• Triple conversion with a 1st IF frequency of 69.450 MHz (SSB/CW/AM • 3 kHz roofing filter equipped as standard feature • TCXO provides ±0.5 ppm High frequency stability (-10°C to +50°C)

Stable 100 Watt Output

The FT-891 provides stable 100 Watts (25W AM) of high power output. High reliability is assured by the transmitters careful circuit design with efficient thermostatically-controlled Dual internal fans and the die cast heat transferring chassis.

32-Bit IF DSP Provides effective and optimized QRM rejection

The 32 bit high speed floating Point DSP (max 3000 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently frustrating while on the HF bands. The highly optimized AUTO NOTCH (DNF) automatically eliminates dominant beat tones, and the CONTOUR, and the APF, are very effective receiver noise reduction tools during HF band operations.
