mAT-180H
Automatic Tuner For ICOM&KENWOOD Transceivers
Instruction Manual Version V3.0
INTRODUCTION
The mAT-180H is an automatic antenna tuner specially designed for modern ICOM and
KENWOOD HF transceivers. It has two control cables to choose from: mAT-CI and mAT-CK.
They are suitable for ICOM and KENWOOD transceivers respectively. With matching control
cables, tuners can be used for corresponding transceivers. mAT-180H standard accessories only
contain ICOM control cable mAT-CI, if you need mAT-CK, please buy more.
When mAT-180H is used in ICOM transceiver through mAT-CI control cable, it is fully
compatible with the original AH-3 and AH-4 automatic tuners of ICOM. Transceivers that can
use both ICOM tuners can also use mAT-180H, which includes IC-706, 703, 718, 7000, 7100,
7200, 7300, 7410, 746, 756, 7600 series transceivers.
When the tuner is used in KENWOOD transceiver through mAT-CK control cable, it is fully
compatible with KENWOOD original tuners, such as AT-250, AT-300. KENWOOD transceivers
that can use mAT-180H are TRC-80, TK-80, TS-2000, 50, 450, 480SAT (excluding HX version),
570, 590, 850, 870, 990, etc. Other types of transceivers can use mAT-180H as long as they
support KENWOOD AT-250 or AT-300 tuners.
In addition to controlling the mAT-180H tuning operation, the transceiver also supplies power to
the tuner through the control cable. Tuners no longer need extra power. Like the original tuner,
the operation of mAT-180H is very simple and convenient. After necessary setting the menu of the
transceiver, the tuning operation can be completed by pressing the tuning button on the front panel
of the transceiver. Even most transceivers can start tuner directly without setting any menu.
The mAT-180H can work within the range of 1.8MHz 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-180H has 16,000 frequency memories. When tuning on or near a previously tuned
frequency, the mAT-180H 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-180H “learns” as it is used, adapting to the bands and frequencies as it goes. You
can also start a tuning cycle manually whenever necessary.
