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.
