The
following installation requires the removal of 1 resistor and the
connection of 7 wires to the main circuit board of the radio. See the
chart for the resistor, AM modulator transistor, AM Power, and AMC
controls for your particular radio application.
Mount
the MD-1 toward the rear of the radio near the Modulator Regulator
transistor on a flat surface of the PC board using the mounting tape
supplied. Mount it on the topside of the board on surface mount radios and
the bottom or solder side of the through hole radios.
Remove
the resistor located near the AM Power control listed for your radio
below.
Connect
the RED wire to 13.8 volts at the audio amp IC or after the On/Off
switch.
Connect
the BLACK wire to ground.
Connect
the ORANGE wire to the hole of the resistor removed that connects
to the power control trimmer potentiometer. (On
the Super Star 121 it will be the pad
furthest
from IC4}
Connect
the YELLOW wire to the other hole of the removed resistor.
Connect
the WHITE wire to the center pin of the AM Mod/Regulator.
For
a switch-able modulator, connect the GRAY wires to a SPST switch.
In the closed position the modulator is off. If a switch is not desired,
leave the GRAY wires disconnected and insulate them with shrink
tubing.
For
the higher power radios such as the RCI 2970DX, Galaxy 93T, and other
radios a 15K resistor may be required across the gray wires of the MD-1.
These radios may require 10-Watts minimum dead carrier for the modulator
to work properly
Set
the power and modulation to your desired settings. Higher modulation
creates more swing.
