One answer you are most likely to receive from the question, "Do these
cause any interference?" will be, "We've never had a report of
interference with any of our installations.". Which is pretty much
meaningless unless they've actually run tests. Hams are too few and far
between for most of these companies to even worry about interference to
or from a ham station. Some, like BPL depended on that being the case.
They figured they could handle the cost of a few problems that *might*
arise. So be wary of the "We've never had a problem" answer.
