What Bitx40 needs is an extra amp stage for the mic.

With my lung capacity down I can't do "haaaaloo" level of yelling anymore so I am using an amped motorola mic.
If you are adventurous try a preamp for the mic with mods and a mic drive control for better control.

An opamp with gain control is better suited for the bitx40. If you don't want to disturb the Bitx40 board then
use a capacitor to couple a preamp.

>If compactness is essential you could use the supplied element and put it in case with the end-cap for the BNC antenna connector (also supplied). As it happens the microphone element fits snugly in. You can pierce two holes in the plastic and use a small press switch (might even have been supplied with the Bitx) for the PTT.
