WCBS Newsradio 880 in HD, FM that is!

[Dan.Strassberg]

Yes, Canada adopted the Eureka-147 system a number of years ago (my
guess, at least 10 years). Eureka-147 uses L-Band (around 1.4 GHz, I
believe). In the US, L-Band is reserved for military communications.
The Canadian system involved grouping broadcasters in each market onto
a single transmitter and antenna. A Multiplexing scheme of some sort
(I don't know whether it's frequency division, time division, or
orthogonal frequency division) divides the signal among the various
stations. In Toronto, I believe that all of the Eureka-147 signals
originate from that very tall tower (I think it's called the CN tower)
that, IIRC, sort of resembles the Seattle Space Needle. Both the Space
Needle and the CN tower have revolving restaurants near the top. I
don't think they use the microwave energy from the antenna to cook the
food or the restaurant patrons (at least, they don't do so
intentionally;>)
