MAT-TUNER
Automatic Tuner For Kenwood & Icom Transceivers

INTRODUCTION

The mAT-K100 is an automatic antenna tuner specially designed for modern Kenwood and
Icom HF transceivers. Each is controlled from a separate control cable. Cable mAT-CK for
Kenwood is supplied with the tuner. Cable mAT-CI for Icom is sold as an accessory.
When the tuner is used with Kenwood transceivers via the mAT-CK control cable it is
compatible with Kenwood AT-300 tuner protocol. TS-2000, 50, 450, 480SAT (excluding HX
version), 570, 590, 850, 870, 990, etc.
When the mAT-K100 is used with Icom transceivers vai the mAT-CI control cable, it is
compatible with the original AH-3 and AH-4 automatic tuner protocol. Transceivers that can
use either Icom external tuner can also use the mAT-K100, including IC-706, 703, 718, 7000,
7100, 7200, 7300, 7410, 746, 756, 7600, 7610 series transceivers.
In addition to controlling the mAT-K100 tuning operation, the transceiver also supplies power
to the tuner through the control cable. Tuners do not need external power. Like the original tuner
operation of mAT-K100 is simple. After setting transceiver menu, tuning operation can be
completed by pressing the tuning button on the front anel of the transceiver.
The mAT-K100 covers 1.8 to 54MHz, at power levels up to 120 watts. It will tune dipoles,
verticals, Yagis, or virtually any coax-fed antenna. Matching range 5-1500 ohms, in excess of the
internal automatic antenna tuner.
The mAT-K100 has 16,000 frequency memories. When tuning on or near a previously tuned
frequency, the mAT-K100 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-K100 "learns" as it is used, adapting to the bands and frequencies as it goes.
You can also start a tuning cycle manually whenever necessary.

AN IMPORTANT WORD ABOUT POWER LEVELS

The mAT-K100 is rated at 120 watts maximum power input at most. Some ham
transceivers virtually all amplifiers, output well over 120 watts.
significantly exceed specifications will definitely damage or destroy your mAT-K100. If your
tuner fails during overload, it could also damage your transmitter or transceiver. Be sure to
observe the specified power limitations.
