Modification for Icom 2SAT




IC2SAT.11

Yeah, the above is crude, just meant to give the relative locations of the
mysterious diode, SP1, R38, R39, R41, R42, R43, and R61.  The 3-terminal
box with an arrow drawn to it (the arrow is in the original image) looks
like the below.  A diode is connected from the lower left tab to the upper tab.

To simplify/fool-proof this, if the schematic has:

                (X) --->|--- (Y)

I'll say "from X to Y".  From the "IC-2SAT IC-2SET SCHEMATIC DIAGRAM":

        Japan Version           D6:     DA115   from KEYI2 to KEYS2
        Europe Version          D5:     DA115   from KEYI0 to KEYS3
                                D6:     DA115   from KEYI2 to KEYS2
        Italy Version           D5:     DAN202U from KEYI1 to KEYS3 and
                                                from KEYI0 to KEYS3
                                D6:     DA114   from KEYI0 to KEYS2
        U.S.A. Version          D4:     DA115   from KEYI2 to KEYS3
                                D9:     ISS254  from KEYI1 to KEYS2
        Australia Version       D5:     DA114   from KEYI1 to KEYS3
                                D6:     DA115   from KEYI2 to KEYS2
        Asia Version            D4:     DA115   from KEYI2 to KEYS3

Now, can anyone use this to figure out the Icom-Europe memo???
