HD4

B

Barry

In the New York City region, WVIP FM is the only station with an HD4 channel. HD2 broadcasts the syndicated Music of Your Life. HD3 offers country music (a musical genre which is scarce on the local airwaves). HD4 is a rebroadcast of sister station WVOX AM.
All channels sound OK, except for HD3. That one is rather tinny, though it used to be worse.
Anyone know of other stations that have a fourth HD channel? How do they sound? I believe there are a handful around the country.
 
WOGL-HD4 Philadelphia running Phillies game broadcasts 24-7. Unique in that CBS isn't licensed to webstream them so the channel can apparently only be heard on HD unless MLB has set up a stream.

In Baltimore, AOR WIYY does classic and indie rock on the 2 and 3 and the HD4 is their sister station N/T WBAL. I believe CBS's Baltimore and DC sports outlets may use their HD-4s as well.

what is the bit rates for the 4 HD channels?

At best, 24kbps. Most likely, 16kbps. (Assuming that the HD-1 is operated at either 48 or 32 kbps.)
 
For WLTJ and WRRK in Pittsburgh:

HD1 through HD3 are all at 32 kbps which equals the 96 kbps total allowed by iBiquity's MP1 configuration
HD4 is in extended hybrid mode and it's 24 kbps, maximum allowed for the Extended-Hybrid Mode

and I have to admit, they all sound better than satellite radio's higher bit-rate channels
 
In Boston, what are the bitrates for the stations that are doing HD-3? The 4 CBS do HD-3 and WGBH-NPR does HD-3?

Dur, I completely spaced on extended hybrid mode. Is it safe to assume most FM-HD broadcasters use extended hybrid now?
