While what you state for matters of scientific reference are accurate, it
still doesn't discount the fact thousands of similar, if not identical
systems are operating in that very same spectrum range at multiple
distances of your friend's system in URBAN areas which have many thousands
of microwave ovens. There is something wrong with your friend's system... 
Not the spectrum in which he's operating.

It's also well proven that water vapor is not a serious path attenuator at
2.5GHZ.  Liquid..yes.  Vapor...no.

The only reason that spectrum range is Part 15 is for the very reason you
cite. All the nukers out there are emitters and the cavity of each oven
will not contain ALL the energy.  So why license services there and at
it's harmonic at 5.8 if they are postential sufferers of intterference
from unintentional radiators?

This is my last post on the matter....
