I think close call really only works horizontally,am not sure that it works going straight up.But again am not sure.
Distance to the source is not overly relevant, although to be 20db above noise, a signal certainly needs to be strong to trigger close call. I have seen situations where close call triggers 2-3+km from the signal source. So close is a relative term.dave3825 said:The close call works in all directions. Up, down, left, right. like stated, the signal needs to be close.
But its also transmitting with 20 Kw.Wirelessly posted (Mozilla/5.0 (X11; Linux i686; U; en-US) Gecko/20081217 Vision-Browser/8.1 301x200 LG VN530)
I've gotten NOAA weather radio on my GRE PSR-500's Sweeper (the same as Uniden's Close Call) and the transmitter is about 22 miles away.
....You're gonna have to get a little closer to the sat.Has anyone had any luck using the close call feature in the bcd396xt scanner I have tried but with no luck at all what other methods using the features in the bcd396xt scanner would you recommend using
