This includes: TRC-80, TK-80, TS-2000, 50, 450, 480SAT (excluding HX version), 570, 590, 850,
870, 990, etc. TS-440 is too old to use this tuner.
Other models of transceivers have not been tested yet. We will update this list after testing.
Installation
1. Connect the HF/50 MHz antenna jack on the transceiver to the “RF IN” jack on the back of
the mAT-180H, using a 50 ohm coax cable rated 120 watts or greater.
Special Notice
: For some transceivers with built-in tuners, such as KENWOOD TS-480,
TS-2000 and TS-590(S/SG), the external tuner must be connected to the ANT1. These
transceivers will not initiate an external tuning cycle if ANT 2 is selected. Because their
built-in tuners have been fixed to ANT2 and cannot be changed. When you don't know how a
transceiver connects to an external tuner, please read the transceiver's user manual carefully.
2. Connect the supplied transceiver control cable to the mini-DIN 4-pin jack on the rear of the
mAT-180H, marked “RADIO”. Connect the other end of this cable to the “TUNER” jack on
the rear of the transceiver. For ICOM transceivers, the control cable is mAT-CI,
it has a
four-pin plug for connecting the transceiver. For KENWOOD transceivers, the control cable is
mAT-CK,
it has a six-pin plug for connecting the transceiver.
Tips: For some ICOM transceivers, such as IC-M710, their TUNER sockets are not standard
4-pin sockets. After retrofitting their "TUNER" sockets, mAT-180H can still be used, just to
ensure that each line in the socket is connected correctly. For the definition of each line in their
sockets, please read the user manual of the transceiver. The same is true for KENWOOD
transceivers.
3. Connect the antenna feedline coax to the “ANTENNA” jack on the rear of the mAT-180H.
4. Grounding the mAT-180H tuner will enhance its performance and safety. We recommends
that you connect your tuner to a suitable ground; a common ground rod connected to buried
radials is preferred, but a single ground rod, a cold water pipe, or the screw that holds the cover
on an AC outlet can provide a serviceable ground. We strongly recommendsthe use of a
properly installed, high quality lightning arrestor on all antenna cables.
TRANSCEIVERS SETTING
Most transceivers can directly use external tuners without any menu settings, but some need to be
set. If you are not sure whether your transceiver needs to set up a menu, read the section on
external tuners in its user manual. For ICOM transceiver, reference can be made to the setting of
AH-4 tuner, and for KENWOOD transceiver, reference can be made to the setting of AT-300 tuner.
Following is an example of ICOM IC-718 to illustrate the menu settings:
IC-718
：
-
Hold down [PWR] for 1 second to turn power OFF.
-
While pushing and holding [SET], push [PWR] to turn ON the power.
-
Push [UP] or [DN] one or more times to select [TUNER].
-
Rotate the main dial to select “4.” AH-4TUNER is selected.
-
Hold down [PWR] for 1 second to turn power OFF.
-
Push [PWR] to turn ON the power.
