What have we learned over the years??

My channel 2 interference is not harmful !!!

I think big money talks and we don't have it, its just a matter of time =
and this fcc will outlaw ham radio!!

  After watching this one point that I continued to think about is the =
FCC's
  (appropriate) concern to assure that current radio services (ours and
  others) are protected from any harmful interference and that there are =
ways
  to mitigate it should it occur.    That almost direct quote got me =
thinking
  about what the definition of "harmful interference" is.   For example, =
if
  BPL raises my receiver noise floor such that I can't hear weak tropo,
  perhaps EME, is that harmful interference ?    What if it raises my =
noise
  floor in only one direction but not others, is that harmful =
interference ?


  The Part 15 definition of harmful interference, the one that drives if
  "mitigation" would be needed,  is as follows:

     (m) Harmful interference. Any emission, radiation or induction that
  endangers the functioning of a radio navigation service or of other =
safety
  services or seriously degrades, obstructs or repeatedly interrupts a
  radiocommunications service operating in accordance with this chapter.

  Hmmm.   It would be nice to have some amateur radio based examples of =
what
  the FCC would consider harmful interference.    For example, looking =
at the
  ARRLs website on various BPL testing to date, are those examples of
  "harmful interference" ?

  Is it possible that with BPL (or for that matter, other Part 15
  technologies) we could have interference that changes our hobby but =
that
  isn't harmful interference ?
