The mAT-30 is an automatic tuner intended for use with modern YAESU transceivers. It works with some YAESU transceiver that supports an FC-30 , FC-40 or FC-50 YAESU tuner; a partial list of compatible units includes: FT-100,FT-857D,FT-897D,FT-450D,FT-891,FT-950,FT-991,FT-991A,FTDX-3000. The operating is the same as the method of the YAESU tuner, which is simple and convenient.
The mAT-30 connects to the transceiver via its CAT/LINEAR jack to control the tuning cycle, the transceivers Tune button controls the tuner. The CAT/LINEAR jack also powers the tuner, so it requires no external power supply. Tuning is performed when the TUNE button is pushed on the front of the transceiver and held for one second.
The mAT-30 can work within the range of 1.6MHz to 54MHz, at power levels up to 120 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some other tuners you may have considered, including the built-in tuners on many radios.
The mAT-30 has 16,000 frequency memories. When tuning on or near a previously tuned frequency, the mAT-30 uses "Memory Tune" to recall the previous tuning parameters in a fraction of a second. If no memorized settings are available, the tuner runs a full tuning cycle, storing the parameters for memory recall on subsequent tuning cycles on that frequency. In this manner, the mAT-30 "learns" as it is used, adapting to the bands and frequencies as it goes.
