Let me preface by saying I already know the general consensus on here regarding Midland products. That being said, I recently got an MXT275 to install in my truck. Most times when transmitting, ANY manipulation of the mic or mic chord results in unintelligible static on the receiving end. Also, when the built-in speaker in the mic itself is activated, it's beyond raspy/rattley. I'm thinking a bad mic chord or plug? Any thoughts?
