XM's LA-site-number 2 is atop Mt. Wilson, where I've seen the equipment, and
I don't mean from the outside of the building. They're in the same building
that houses KCET, the southern-most one.
5800 feet elevation amsl. With satellites and this boy, they still needed
illegal transmitters. Not exactly a ringing endorsement of COFDM or SFNs.

What I found interesting in this piece was that in addition to its satellite
transmitters, XM Radio needs, for example, 91 "small sticks" to cover NYC,
and 39 small sticks to cover LA. Furthermore, that at least some of these
"small sticks" are tall. They mention one example of a sanctioned 490'
antenna height turning out to have been 900' in fact. I don't know how many
of their small sticks are that tall. Seems to me that many were, they would
be more obvious. Perhaps they are sharing TV towers in some cases?
The article talks about power level and location violations, without
mentioning what the power levels are.
Apparenty, Sirius, with 3 ellyptical orbit satellites, depends less on
terrestrial repeaters than XM, with two satellites in geosynchronous orbits.
The NAB is against the possible merger of these two companies. Best I can
tell, the NAB's concern is that such a monopoly would have so much content
buying power that local stations would be shut out of competition. Although
the NAB also makes arguments which I find puzzling. For example, that such a
merger would reduce innovation and increase prices for satellite radio.
Probably true, but it sounds to me like that would work to the NAB's
advantage.
