Enables more sensitive transmit above the 2 meter
band. (148 to about 162 MHz; after that, sensitivity drops off.)
Keeps sensitivity for the FM broadcast band.
-
Open the top of the radio by removing the 3 top screws and 2 side
screws. Look at the radio from the with the front panel facing you.
-
Note the silver rectangular box near the middle of the PCB marked
something like "9 MHz SSB Filter".
-
Move your eyes up from this filter toward the back of the radio.
Follow the ribbon cable up. Notice a wide white connector with
several colored wires in it on the back of the PCB.
-
The fourth wire from the left is a yellow wire. Cut this wire.
Rather than cutting it, you can remove the connector, stick a paper
clip in the side of the connector under the wire, push it in, and
pull the wire out. Be careful not to remove the other yellow wire.
-
Re-insert the connector back to its original place on the PCB.
-
Open the bottom of the radio. You will again need to remove 5
screws.
-
Look at the radio with the front panel facing you. Note 5 tiny
transistors behind the MENU button. Follow the trace from the
middle transistor to a hole just to the left of jack J8.

Solder wire into this hole ^
-
Solder a small wire into this hole. Be careful not to apply too
much heat; use a low-wattage soldering iron. Be careful not to
damage the PCB or the grey cable coming out of J8. Use a magnifying
glass.
-
Run the other end of the wire you just soldered to the front of
the radio and attach it to the yellow wire you just cut.
-
Re-assemble the radio.
