I attend a southern Baptist church where the pastor teaches that Baptists are not protestants and also that man is made in the image of Adam and not God since Adam messed it up.

SOURCE: Popping over the house speakers.

Has it always done this or recently started?
Try to determine if the popping is coming from the words spoken into it, or if you get popping from simply moving the mic and cable around. if you get popping from simple movement, there is a chance that the mic needs to be replaced. We use these in our church, and over the last 6 years I've had to replace about 6 of them...sometimes they go bad in the wire, sometimes inside of the mic. The wires are so thin, excessive use wears them out sometimes. Depending on the model countryman that you are using...I've seen them become disconnected where the mic. meets the wire...some can disconnect here beneath a rubber coupling...if you have this model, make sure that it is properly seated.
If there are no shorts in the mic or cable, and you only hear the popping while speaking into it, you may need to filter out the low end on this channel only (everything below about 120hz - 180hz)...and try using a wind shield to help control this.
Hard to troubleshoot without being there, but I hope this gives you a few good ideas.
