I'd say that "spurious" doesn't even describe the level of noise in
that "signal". More like pure trash.

The noise floor is about -80 dBm, not bad in the middle of a city. All
the other stuff is there on purpose: AM, FM, TV, HDTV, all that. The
*content* of most of those signals are certainly trash, but that's
another issue.
