To bad your not in my neck of the woods I could convert that radio to a
standard 4 or 5 Pin connector.

As for Mic Gain, it is used to increase the signal (Your Voice) to the
radio. Just like a Car audio amp Gain, it is not a volume control. If it is
truely a Gain circuit, cranking the gain will usally induce alot background
noise or may feedback.

I bought a used Cobra 41 Plus CB, without the manual. The first
pushbutton on it is labeled NB. What exactly is this? I can't tell
that it does anything when it's pushed.

Also, the mic for the 41 Plus is a smaller DIN-type connector with 5
or so small pins. Do they make adaptors which will allow me to
connect a regular 4-pin mic connector to the 41 Plus?

Finally, what is the Dynamike control supposed to do?
