Mat-Tuner mAT-705 Instruction Manual

Automatic Tuner for ICOM IC-705 Transceiver

INTRODUCTION

The mAT-705 is a compact antenna tuner designed for ICOM IC-705 transceiver.
connects directly to the TUNER socket of the IC-705 through a dedicated control cable mAT-705-
CB supplied as a standard accessory of the tuner.
The tuner uses an all-aluminum metal shell. Front panel uses aluminum milling technology and
laser engraving. Water-resistant but not water-proof, suitable for outdoor portable use.
The mAT-705 tuner is powered by a standard 9V alkaline battery, convenient for users to replace
and for air transportation. Magnetic latching relays are used inside the tuner to save energy and
inhibit the need for battery replacement. Consumes zero power when turned off. When powered
off, retains the last frequency setting used and will be ready to operate when powered back on.
In addition to the tuner, the mAT-705 package includes control cable mAT-705-CB, and L-shaped
wrench (for opening the case for battery replacement), and user manual. The user manual latest
version can also downloaded directly from our web page.
The tuner comes with control cable mAT-705-CB. Both ends of the control cable are standard
3.5mm plugs. One side is connected to the TUNER socket of the transmitter, and the other plug is
connected to the CON socket of the tuner. The transceiver controls the tuner through this cable for
automatic tuning. An RF cable mAT-RC1 that connects the Icom 705 and the tuner is sold as an
accessory item. mAT-RC1 is a common coaxial cable with male BNC plugs at both ends.
The tuner operates from 1.8 MHz to 54 MHz with a impedance matching range of 5-1500 ohms.
The mAT-705 has 16,000 frequency memories. When tuning on or near a previously tuned
frequency the mAT-705 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-705 "learns" as it is used, adapting to the bands and frequencies as it goes.
