Oftentimes, if the cable is leaking in the upstream, its also leaking in the
downstream. Depending on his country's standardized CATV spectrum, there
may be an analog channel mapped close to our Ch.7 whose aural carrier can be
demodulated with a general coverage VHF receiver or handie-talkie. That
will provide some good clues.
