- This is not necessarily true.
-
- Simple inversion helps me against my neighbor with a cordless phone (unless
- it's another Motorola). It doesn't help me against anyone wanting to
- eavesdrop for real.
-
- As long as I know how good (bad) it is, it helps, I suppose.
-
- If I ever let myself believe it's really secure, I'll be seduced into
- behaving with it as if I had privacy -- and would therefore reveal more
- than I should.
-
- In that case, "some basic scrambling" is far worse than having no
- scrambling at all.
-
- The best case would be the old ham radio sets with speakers and microphones
- -- no headphones, no phone handsets -- with the large antenna outside the
- window -- reminding you constantly that your words are being broadcast.
