> I tried using the Canopy system at 900mhz. Just three miles, nada. Canopy is wide band, but I still expected a link. Then I looked at the spectrum and it was BAD in downtown.

But that was like a hundred years ago...

Hmmm.  The RTL-SDR and better SDR solutions generally cover the 900
MHz band.  It should be possible to get an idea just what the local
noise issues are.
