On my BC246T, when I use Close Call w/ both VHF and UHF enabled, it hardly picks anything. But when I select only VHF or UHF, it works much better. For example, I was at an airport and an employee keyed up his handheld about ten yards away. I had VHF Hi and UHF enabled for CC. Nothing. Turned of VHF Hi and nailed the UHF freq right away. Why does the interference (and I think the "RF field") on VHF affect UHF readings? I'm not sure if I really understand how Uniden's Close Call works, especially with different bands selected. Thanks
