Well, after we have learned about Iridium and how they get information out of the noise I would be more paranoic. Weak signals are a matter of math rather then of amplifying. And the flanks of digital signals are nice.

By the high frequencies used in the comp and there digital nature (what ends up with even higher frequencies, look up fourier transform on rectangular function) shielding is very tricky. One CD tray out of plastic or a badly connected socket is enough. Cooling fans are a problem too.
