IC735.2

    IC-735 Modification NOT Verified.
           D89 by IC25 on the MAIN board appears to be connected to the
           'MUTE' line on the microprocessor. According to the Shop
           Manual, the purpose of D89 is to disable the transmitter
           outside of the HAM bands. Again, I have not verified this
           yet.(The Shop Manual arrived after I figured out the purpose
           of D89 from the schematic that came in the Owner's Manual
           so I am reasonably sure about my findings.)
