                  MODS FOR NEW MODEL ICOM 32AT

1.  Remove battery and back screws (4).  
2.  Loosen (only) top screws (2), bottom screws (4), and PTT
    screws (2).
3.  Lift bottom of front panel 1/2" and slide down 1/2".
4.  Unplug speaker/mic connector.  Try not to disconnect ribbon cable.
5.  There are five diode locations to the LEFT of the back of the speaker.
    (Note:  If they are to the RIGHT of the back of the speaker, and if there
    are some components above the back of the speaker, you have an older model.
    Just move the diodes until they are in positions 3 & 5 (counting from the
    top down).  This will only enable expanded UHF & 10 MHZ digit entry, not
    crossband repeater operation.)
6.  Diodes should be found in locations 2 & 4 counting from the top.
7.  If so, move the diode from location 4 to location 1 (leave the diode at 2).
8.  This expands UHF receive & allows keypad entry of the 10 MHZ digit.
9.  But, the further you get from the ham band, the more unstable the rig is.
    If there's a U where the memory channel should be, you've lost phase lock.
10. Install a diode at 5 if you want to make your rig a crossband repeater.
11. Do a CPU reset by holding both FUNCTION and [A] then turning on power.
12. For crossband repeater operation, enter a simplex frequency in the VHF
    VFO and then enter a simplex frequency in the UHF VFO.  Hold FUNCTION and
    consecutively press [C] [6] [D].
13. To stop crossband repeater operation, you must be in receive mode (i.e.,
    nobody transmitting).  Hold FUNCTION and consecutively press [D] [C].


DIODE LOCATIONS & FUNCTIONS:
