MAT-TUNER
HF-SSB Automatic Antenna Tuner
INTRODUCTION
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. The interface
cable is included. The operating is the same as the method of the Yaesu tuner, which is simple
and convenient. The mAT-30 can work within the range of 3MHz to 54MHz.
The mAT-30 connects to the radio 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. The mAT-30 is specially engineered to integrate with your
Yaesu FT-100/857D/897D/450D/891/950/991 HF radio. Tuning is performed when the TUNE
button is pushed on the front of the transceiver and held for one second.
The mAT-30 provides automatic antenna tuning across the entire HF spectrum plus 6 meters,
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 is specially engineered to integrate with your Yaesu FT-100/857D/897D/450D/
891/950/991 HF radio. The mAT-30 connects to the CAT (Computer Automated Transceiver) port
on the back of the radio. The CAT interface allows an external device such as a PC or the mAT-30
to control the FT-100/857D/897D/450D/891/950/991 by sending it serial commands. The
mAT-30 takes advantage of this interface to simplify the tuning process -- one button push is all
that is needed in order to switch the radio to FM mode, reduce output power, transmit a carrier,
measure the transmit frequency, and then restore the radio to its previous mode and power
level!
The mAT-30 also features advanced memory tuning, providing 16000 memory locations; when
tuning near a previously used frequency it will recall the settings for nearly instant tuning. It
learns your favorite frequencies and bands as you use it. You can also start a tuning cycle
manually whenever necessary.
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.
SPECIAL EXPLANATION:
After actual comparison test, mAT-30 is the only tuner that can tune the antenna with
SWR higher than 3 when FT-891 is matched. Even the Yaesu brand tuner can't do it.
