>Yes, Digital Radio is the same thing as DAB, and my understanding is that
>Canada is indeed using the European standards. They're using microwave
>frequencies (same as mainland Europe? They are NOT using the 219MHz
>channels which I understand are in use in the U.K..)
>
>In USA, different stations in the same city have very different power
>levels. Here in Nashville, powers of MW stations range from 0.5KW to
>50KW, and of FM stations from 0.6KW to 100KW. These are for main stations,
>there are also low-power relays between 0.01 and 0.25KW. DAB would
>result in all main stations having the same coverage, and this is a
>political problem. I also think radio stations are afraid the government
>will want to charge higher license fees if they use new microwave
>frequencies for DAB. (TV stations have had to use a lot of political
>pressure to prevent higher license fees for digital TV)
>
>MW, FM, and TV DXers don't seem happy about digital, but I don't think
>it will be all that bad:
>
>1. Some countries will convert to digital much sooner than others.
> When most of the MW stations in richer countries (USA, western
> Europe, etc.) have converted to digital, the MW dial will be
> more open for DX from poorer countries.
>
>2. Tropospheric DX will still work with digital, even on microwave.
> The current microwave DX record is over 4000km (California to
> Hawaii) and within Europe, DX of over 2000km has been experienced
> by radio hams.
>
>3. I think all DAB systems will include full RDS information. RDS
> is not very popular in the USA (and is not used on MW) so it can
> be very difficult to ID smaller USA stations. DAB will probably
> make this much easier.
