RX receive circuitry can be modified to receive from 118 MHz to 174 MHz. This requires the removal of a surface mount diode D 11 from the Logic Board. It is the only non SMT-Diode of the Logic Board.
TX transmit circuitry can be modified to transmit from 136 MHz to 174 MHz. This requires the removal of a surface mount diode D 13 from the Logic Board. D 13 is near by D 11.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
