Know before you buy
The M-70 is designed for use with most Yaesu HF transceivers. Because it includes both 8-pin round and modular connector cables, it offers broad compatibility across the Yaesu radio lineup.
Yes, the microphone requires a 5.0V DC power source. It is designed to draw this power directly from the microphone jack of compatible Yaesu transceivers.
The Low-Cut filter helps remove unwanted low-frequency rumble or background noise. This results in a cleaner, more articulate signal that is easier for other operators to understand during busy band conditions.
Yes, the M-70 features a one-touch PTT key lock. This allows you to lock the microphone in transmit mode for extended periods, preventing hand fatigue during long contests or nets.
While the M-70 is specifically engineered for Yaesu HF radios, it is a condenser microphone. To use it with a computer, you would need an appropriate interface or adapter to supply the required 5V power and convert the signal to a format your computer accepts.
The isolation transformer helps eliminate ground loops and reduces electrical noise interference. This ensures that your transmitted audio remains clear and free from the hum or buzz often caused by complex station setups.
