BSO on the radio - not for me anymore
Tue Oct 26 16:19:08 EDT 2010
So I used the WGBH web site feedback form to ask how they divvy up
the WGBH-FM HD bitstream. The good news is that I got a clear
answer. The bad news is that listening to live BSO at 48
kilobytes/sec is not what I consider worth chasing. Sigh. I suppose
just knowing they use 3 HD channels should have been a large clue
that HD2 wasn't going to be very hi fi.
This from our engineer: The rates for HD on WGBH 89.7 are: 48/48/24
As for the brittle sound, the Sony does have good receptivity but it
is a table top radio which can have a hard sound to it. There are
tuners available that can be plugged into the big home systems that
might sound better.

"Being clueless about the variations on the HD theme, is HD2 the same
or lower quality [bitrate] than HD1? Or will that vary depending on
the station [WGBH in this case]?"
What most HD stations appear to be doing is keeping the HD1
(simulcasting the analog) at the highest bitrate and running the
secondaries at lower bitrates...for example, 48kbps for HD1 and
24kbps for HD2, 3, etc. But, bottom line, it is up to the station
how the data stream is subdivided.
