1. Remove battery and antenna.
2. Loosen two screws on top of unit as much as possible without removing them.
3. Loosen 4 flat head screws on bottom of unit 1 turn.
4. Loosen 2 screws near PTT switch 1 turn.
5. Remove 4 black screws on back of unit.
6. Lift bottom of front cover .25 inch, slide it down .25 inch, then lift
front cover up 1 inch.
7. Disconnect plug on 4 wires coming from the speaker.
<< THe flex cable can be disconnected from the main board by gently
pulling up on the ears of the connector for that cable on the main board>>
8. Lay front panel on table up-side down being careful of the flex circuit.
9. All mods are done to the back of the front panel. Notice places for 5
axial diodes, which I will call 1 through 5, 1 being nearest the display.
<<These are on the right hand side of the back of the front panel>>
Add/remove diodes so there are diodes in positions 3 and 5. This will
open up receive coverage for VHF & UHF and enable keyboard entry of the
10 MHz digit.
<< I seemed to have the same coverage with and without diode #3 installed>>
When you go out of the range the radio will receive a U appears in
place of the memory channel number. It means the PLL circuit has
lost lock and the radio will not work.
10. Notice 4 surface mount resistors slightly left of center directly
above the speaker, lined up in a row. Solder the anode (the side
without the bar) of two diodes to the right side of the lower of
the four resistors.
