"Canada in Digital Radio Limbo"

"OTTAWA, Ontario — Going nowhe These two words succinctly sum up
the state of Canadian digital radio broadcasting, or DRB.

Despite years of offering Eureka-147 DAB simulcasts of AM and FM
signals in L-band (1452–1492 MHz) in major metro markets, broadcasters
have virtually no listeners and no market profile.

“L-band DAB is in limbo,” said Canadian broadcast technical consultant
Wayne Stacey, who has been involved with Canadian DRB for the past 20
years. “In fact, from a transmission standpoint, the band is dying.”

I haven't got time to read the rest, but thought I should say the Canada
have never really pushed their DAB radio system.

Also having it only on L-Band probably didn't help, as that makes it
very expensive to provide any reasonable coverage. I seem to remember
reading that coverage was very limited, and there were sod all receivers
available in the shops.

Using frequencies in the Ghz range is pretty dumb for an earthbound broadcast
system that needs to penetrate hills and buildings. You'd think they'd have
figured that out before they started the tests.

As for recievers - my Denon picks up L Band but its the only one I know of.

Does it pick up anything at all?..

There were test transmissions here in London for years but they stopped them
last year. Last time I checked a few months back there was nothing there. Or
no DAB broadcasts anyway.

XM has decent coverage on S Band.

Its via satellite so there usually won't be half a city between the
transmitter and your radio. Does it work indoors? I'll bet it doesn't.

XM is a hybrid satellite/terrestrial system. They cover a good deal of
Los Angeles with a 10 KW transmitter on Mt. Harvard. It gets indoors
surprisingly well.

Given that my 100mw wifi system which also operates in S band can barely
penetrate 2 walls in my house I find that rather surprising but I'll take
your word for it.

IBOC : 'Digital' FM HD-Radio with HD2 Channels in Canada Makes Sense Too...

Dave,

Canada gave-up on Eureka-147 DAB and opted for
the American XM/Sirius Satellite Radio System with
some Canadian 'Content' = what-works-works-! ~ RHF

Plus Canada has a agenda for a more active and
aggressive 'transition' from the old AM/MW Radio
Band to the larger; almost exclusive use of the FM
Radio Band as a Local City/Metro {Community}
Urban Radio Service with the fewer AM/MW Radio
Stations being utilized as Regional/Provincial Radio
Broadcasters serving larger Rural Areas having fewer
people per 10,000 km2, ~3,861 Sq.Miles
http://en.wikipedia.org/wiki/Rural_Canada

Majority of the Population ~85% in "Clusters" in
Localized City/Metro Areas : That are best served
by the FM Radio Band Stations.

Much Smaller ~15% of the Population Dispersed in
vast Non-Localized Rural Areas : That are best served
by the AM/MW Radio Band Stations; with a few
Shortwave Radio Stations too.

Plus Canada has 50% of it's Population within 50km
of the US Border; and 75% of it's Population within
100km of the US Border.
http://www.unitednorthamerica.org/canadapop.htm
Meaning American FM Radio Stations in equal numbers
to the number of Canadian FM Radio Stations provide
indirect Radio Service to this large segment of the
Canadian Population.
http://www.howderfamily.com/blog/can...to-the-border/
-and- YES Canadian's do Listen to American Radio.

So... *IF* IBOC 'Digital' FM HD-Radio in the USA ever
becomes 'established' and 'accepted' in the USA : As
the Standard form of FM Radio Listening and thus the
Standard means of FM Radio Broadcasting : You can
expect that IBOC 'Digital' FM HD-Radio will also in-time
become 'established' and 'accepted' in in Canada :
Just due to the close proximity of the vast majority of
the Canadian Population to the USA along the Border;
and the simple fact that American Radio Signals :
DO NO STOP AT THE BORDER [.]

It Remains MHO that the Future of Terrestrial Radio
Broadcasting in the USA is FM Radio; and the Future
of FM Radio is IBOC 'Digital' FM HD-Radio with HD2
Channels in the USA.

NOTE : IBOC 'Digital' FM HD-Radio* with HD2 Channels
in Canada makes sense too. One Radio Station on One
Frequency with an HD1 Channel in English; and an HD2
Channel in French; or an HD2 Channel in the Language
of one of the Local First People's of Canada.

* Single Point {Co-Located} Radio Service Serving a
Diverse Bilingual & Bi-Cultural Population.

Conclusion : IBOC 'Digital' FM HD-Radio* with HD2
Channels represents both Economy and Efficiency
in Canada as a National Nation-Wide Radio Service.

They thought at one time that it would be good to replace analog
low-power community radio and perhaps local radio. National and some
regional radio could use Band III.

Perhaps replacing a low power FM TX of lets say 10w, with an L-Band TX
or 100w or so. I suppose that would be financially feasible, although
I'm not sure how well a low power L-Band TX would be received by in door
portables.

Same as GPS reception indoors I suspect.
