IC32AT

                    MODS FOR ICOM 32AT

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.
