The film involves a kid with a ham radio(?) making contact with a man at a satellite station in some snowy place(I'm thinking Alaska), and the man witnesses the murder of a man in what I think is Russia. Throughout the movie, he tries to find the location of where this happened, and I believe he goes there and almost gets killed. I know this is pretty vague, but it's jumbled in my head. Saw the film a bunch of times when I was younger. Cellular and Frequency(minus time-travel) remind me of the film I'm thinking of.
