I don't talk on extra channels so I might have that switch in the wrong position causing modulation to be not where it supposed to be. It might be fine if that's the case. If you know how to turn these up whether inside or power mic than this is for you. I've stated any info on it that I know of. This is a awesome radio and you don't see many for sale.
