The batwing ant. has an amplifier built into it. it gets it's power through the ant. wire so he power must be on all the time. Check the connection to the ant,make sure it is good. One other thing to check is the wall connection for the cable to the TV. It is possible that they are marked wrong as was the one in my rig. The radio will have a ant. connection on the back of it. In most cases it is a single wire coming from it. Try to get it as high as you can Just pull it up and drape it on something. If it has an ant. connection outside as an Arial, check to see if it is connected. An ant. connection outside is not usual for a radio in a TT.
