I want to hook up a dipole antenna to the radio in my garage. There are no provisions for the hook up. Is there any other way to hook it up? Also, I have a police scanner that quit working the other day. It scans and stops on channels but there is no sound. I also can turn the squelch all the way up and it makes no sound at all. I took it apart to make sure the speaker wires were on. That was the extent of my knowledge. TIA
