Wireless DSL??? First I've heard of that one. I would say that if
you're hearing it on the FR-200 there's probably a Part 15 violation
going on. It's probably being radiated from the telephone lines and
may be due to an excessively high signal level. Wireless broadband
devices (access points, routers and the like) should be undetectable
on the FR-200 since they're based at 2.4 GHz or higher.
