DAB Radio in Canada

On Friday it was not possible to get any DAB station in Toronto except the CBC stations. This continued through the weekend and the last time I checeked this morning. Over the past 5 years there have been temporary disruptions(I assume for maintenence) but nothing to this degree. Does anyone have any information about this, or want to speculate.

The room got to hot and the FM transmitters were having problems with it.
So, to prevent overheating, DAB was shut down.
Glad to see someone noticed.

Thanks Tom, I can enjoy my investment in DAB a little longer(hopefully a lot longer). Would you happen to know why EZ ROCK 97.3's DAB signal is significantly different(low volume) than the other stations?

But, after realizing what’s going on (so very, very few people actually having DAB capability specially home units) don’t you feel real lonely?

Believe me I wish it wasn't the case.

I don't know if this is true, but there was a rumour that in communist Albania for many years the evening news on their TV channel started with "Good evening, Mr. President!". He was the only one in the country with a TV set.
That effectively makes you second in history, which is not that bad either

If there were DAB broadcats in Calgary I probably would have made some investment too. Unfortunately, until recently I didn't even know there were broadcasts in Canada at all. We missed the beginning, at least let us know when it's over

Cool DAB radio vs CBC - Sirius / CRS - XFM sat radio

Except for the mobile differences sat being North Americam wide in it's reception
vs DAB which needs each city to offer channels and diiferent tuners to recieve it .
My question is on the difference in "CD like quality " I know some people have reviwed the sat services and said it is close to CD qulity but does DAB city stations have better dynmaic range and sound quality then the sat services ?

Has anyone got links on relevant technical comparison information ?

I for one would be purchasing based on quality and not quantity of channels available ...

Those who say that CD radio has "CD like quality" are either selling XM or Sirius units, or as so clueless that can't tell AM from FM sound quality. Disregard those comments wherever you see them. The best channels on XM and Sirius are worse than proper FM analog station and sound like total crap compared to CD. DAB just can't be worse than sat.

Thanks for the clarification A.D as I kind of new that was the case for sat radio the ( MP3 sound of the skies ) and was curious to see if DAB improved things enough to be viably better than FM radio audio ...I guess time will tell ...

I think i've seen it mentioned here somewhere before, but unfortunately, each broadcasters sets thier own levels, audio comprssor etc. Most are still using analog into the DAB encoder.
Hard to find good help these days.....

Reports out of EU say the very highest bit rate DAB is very very good. Many broadcasters however broadcast as low as 64kb to increase the number of channels on a given transmitter.

Thanks for the reply Tom.F.1, feel free to share more "inside" information about DAB while it's still around. In response to rockhard's question on DAB vs. satellite, the only comparison I can make is DAB to Direct tv's music channels(I do not have XM or Sirius). In this situation it's no contest DAB is much better. DAB can sound awesome if the broadcaster makes an effort. Most music stations in Toronto transmit a 224kb/s signal, however a 192kb/s signal can great depending on the processing. The talk stations generally don't need a high bit rate. I've read in Germany they use 256kb/s which is supposed to sound phenomenal. In the summer of 2001 CBC tried a 256 signal here in T.O. but the Arcam reciever I use would'nt accept it do to a protection limit(whatever that is). When I notified the CBC of the problem they were kind enough to lower it to 224(ah, the benefits of being the only listener).

Tom.F.1., is there any talk you're aware of in Canada regarding scrapping DAB and switching to "HD Radio"?

I do not know of any others. One reason I joined this forum was to get feedback from other DAB users but no luck yet.
