I am a newbie. I just bought a motorola voom reciever off of ebay.I am having trouble getting the reciever to lock onto any local channels.When I go into the systems menu and aim the antenna I get a strong signal on channels 24 and 35 signal of 95 and 99 on each but when i scan for local channels the reciever does not lock onto any channels.i live in the Oklahoma City,OK area and have software ver.2.4c on the reciever.Any suggestions would be appreciated.
