Microphone settings advice:..Especially lowering to 25%

This is a noise canceling microphone:
Don't forget the lip guard is there to remind you of the close spacing required. To best describe the spacing,  I would say your lips should almost drag the screen when talking. With this close spacing,  you would set the gain slide to about 10-25% mic setting if you have a bold louder voice.  Soft spoken folks are at more of a 30-40%.  There is rarely ever a time that it requires more than 60%. EVER.


The item most overlooked when ordering a custom radio is the microphone.  Your new tuned radio will NOT sound great with a stock mic on it.
 If your CB is more than a tool for work, you NEED to upgrade your microphone.  My personal favorites are the Astatic 636L and RD104E.
