Subj: FT 736R Extended Frequency coverage. I've received the modification information for the aforementioned radio. Remember, this is for CAP/MARS use only - Amateurs are NOT permitted to transmit outside of the Amateur bands without specific authorization. The mods take place on the 144 main unit (No. 6XXX). The diode array is in the lower left corner of the board, component side towards you, and the notches to the left. No information was given as to diode type, but I assume any small signal diode will work.
