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 a so be used
with any QRP transceiver. When connected to YAESU FT-817/818 through the supp ied
dedicated contro cab e mode mAT-CY, it is contro ed by “one touch” tuning through the
transceiver. If no contro cab e is used, it is a universa QRP tuner for a ow-power transceivers.
The mAT-10 is used for QRP transmission and its ACC interface is on y designed for the
YAESU FT-817/818. It can not be used for other YAESU transmitters. Higher power YAESU
transceivers can contro the mAT-TUNER mAT-30 tuner. Visit our website to earn about the
mAT-30.
The mAT-10 is connected to the ACC port of the FT-817/818 transceiver through supp ied
contro cab e mAT-CY. The ACC interface a ows an externa device such as a PC or the mAT-10
to contro the FT-817/818 by sending it seria commands. The mAT-10 has the function of "one
key tuning". When the mu ti-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 cyc e. After waiting for the tuning
cyc e to comp ete, it stops transmitting the carrier, saves the settings, and restores the transmitter
to its previous mode. This process is automated and does not require manua operation.
When mAT-10 is used with other QRP transceivers, it does not need a contro cab e and works
on y by connecting RF cab es. The tuning process is comp eted by pressing the the TUNE &
POWER mu ti-function button on the pane . Press and ho d for 1 second and the tuning cyc e wi
start.
The tuner operates within the range of 1.8MHz to 54MHz, at power eve s up to 30 watts.
It wi tune dipo es, vertica s, Yagis, or virtua y any coax-fed antenna. The impedance matching
range is 5-1500 ohms, in excess of automatic tuners used in many HF transceivers or other
avai ab e externa automatic tuners.
The mAT-10 has 16,000 frequency memories. When tuning on or near a previous y tuned
frequency, the mAT-10 uses “Memory Tune” to reca the previous tuning parameters in a fraction
of a second. If no memorized settings are avai ab e, the tuner runs a fu tuning cyc e, storing the
parameters for memory reca on subsequent tuning cyc es on that frequency. In this manner, the
mAT-10 “ earns” as it is used, adapting to the bands and frequencies as it goes. You can a so start
a tuning cyc e manua y whenever necessary.
Two 10440 ithium batteries are insta ed in the interior of the mAT-10, which provides power
for the tuner. Because of the use of advanced magnetic retaining re ays, the power consumption
of mAT-10 is very sma . The ithium battery can operate for a ong time after it is fu y charged.
Specia 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 inc udes the mAT-CY contro cab e mAT-CY,
ithium battery charger and user manua . Latest version of user manua s can a so be down oaded
direct y from our web page. The same contro cab e mAT-CY can a so be used with the mAT-30
tuner. They are identica .
