Enhancement of Microphone Frequency Response
===============================
Remove top cover of the radio and with the display facing you and the radio
upright locate IC3 (MJM45585) near the bottom right hand corner of the main
large board.
Just to the right of this IC locate c75 (56 pf) and remove it. This will
increase the gain of the microphone Preamp considerably but without
overmodulation.
