Very simple cut and dry mic mod to get rid of some of the drowned out muddy tones the stock mic is known for. Before you do this mod please make sure you disconnect the mic from the radio. What works for me might not work for you. This basic mod is perfect for the using this radio in a base operation vs a windy/noisy car. This will void your mic warranty. In the pictures I show a Kenwood mic, They are the same as the Btech mics. Click the pictures to go full screen.
