Connector/Switch
Description
J1
TRANSCEIVER
Connects to transceiver ACC connector.
Provides power to the transceiver and
translates control and data signals between
the transceiver and the MT-1099A.
J2
AMP CNTRL
Connects to an external amplifier (RA100,
RA400-99). Provides 12 Vdc to the external
RF power amplifier and translates control
and data signals between the MT-1099A and
the external amplifier.
J3
TUNER CONTROL
Connects to antenna tuner (RAT7000B or
RAT1000C). Provides power to the antenna
tuner and translates control and data signals
between the MT-1099A and the antenna
tuner.
J4
DC OUT
Connects to the RA100 (or RA400-99) RF
power amplifier. Provides 12 or 24 Vdc to
the RA100 or 24 Vdc to the RA400
amplifier.
J5
DC IN
Input power connector (12 or 24 Vdc).
S1
Power switch
Three pole switch turns DC power on and off
and turns on audio to built-in speaker.

Setting
Description
OFF
Turns off DC power to the MT-1099A. Indirectly turns
off power to the transceiver, antenna tuner and built-in
speaker. The external amplifier (RA100) receives power
(12 or 24 Vdc) through the DC OUT J4 connector with
the power switch off.
POWER ON
Turns on power to the MT-1099A. Also provides power
(12 Vdc) to the transceiver and antenna tuner. This
position does not provide audio to the built-in speaker.
SPEAKER ON
Turns on power to the MT-1099A. Also provides power
(12 Vdc) to the transceiver and antenna tuner. This
position also provides audio to the built-in speaker.
