mAT-10
Automatic Tuner with QRP Transceivers
Instruction Manual Version V1.0
INTRODUCTION
The mAT-10 is a compact and tuner designed for YAESU FT-817/818, that can also be used
with any QRP transceiver. When connected to YAESU FT-817/818 through the supplied
dedicated control cable model mAT-CY, it is controlled by “one touch” tuning through the
transceiver. If no control cable is used, it is a universal QRP tuner for all low-power transceivers.
The mAT-10 is used for QRP transmission and its ACC interface is only designed for the
YAESU FT-817/818. It can not be used for other YAESU transmitters. Higher power YAESU
transceivers can control the mAT-TUNER mAT-30 tuner. Visit our website to learn about the
mAT-30.
The mAT-10 is connected to the ACC port of the FT-817/818 transceiver through supplied
control cable mAT-CY. The ACC interface allows an external device such as a PC or the mAT-10
to control the FT-817/818 by sending it serial commands. The mAT-10 has the function of "one
key tuning". When the multi-function key on tuner is pressed, the mAT-10 command FT-817/818
switches to FM mode and transmits a carrier to initiate a tuning cycle.
After waiting for the tuning
cycle to complete, it stops transmitting the carrier, saves the settings, and restores the transmitter
to its previous mode. This process is automated and does not require manual operation.
When mAT-10 is used with other QRP transceivers, it does not need a control cable and works
only by connecting RF cables. The tuning process is completed by pressing the the TUNE &
POWER multi-function button on the panel. Press and hold for 1 second and the tuning cycle will
start.
The tuner operates within the range of 1.8MHz to 54MHz, at power levels up to 30 watts.
It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. The impedance matching
range is 5-1500 ohms, in excess of automatic tuners used in many HF transceivers or other
available external automatic tuners.
The mAT-10 has 16,000 frequency memories. When tuning on or near a previously tuned
frequency, the mAT-10 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-10 “learns” as it is used, adapting to the bands and frequencies as it goes. You can also start
a tuning cycle manually whenever necessary.
Two 10440 lithium batteries are installed in the interior of the mAT-10, which provides power
for the tuner. Because of the use of advanced magnetic retaining relays, the power consumption
of mAT-10 is very small. The lithium battery can operate for a long time after it is fully charged.
Special chargers are provided with tuners. You must use its own charger to charge the tuner. It is
dangerous to charge with an incorrect charger.
In addition to the mAT-10 tuner, the package includes the mAT-CY control cable mAT-CY,
lithium battery charger and user manual. Latest version of user manuals can also be downloaded
directly from our web page. The same control cable mAT-CY can also be used with the mAT-30
tuner. They are identical.
