Spam: WCBS Newsradio 880 in HD, FM that is!

Thu Oct 2 16:10:48 EDT 2008

But reception of the HD-n (where n>1) subchannels is particularly
problematic in cars. If you lose sync with the digital stream and you
are tuned to the main HD channel (HD-1), the receiver automatically
falls back to analog, and if everything has been set up correctly, the
fallback is not very noticeable, if not entirely aesthetically
pleasing (frequency response changes; stereo switches to mono). With
the n>1 subchannels, no analog stream carries the same content, so my
understanding is that the fallback is to silence. I've seen reports
(from HD radio proponents campaigning for higher subchannel power on
the FM band) that claim that, with the current power levels,
reliability of the digital streams is simply unacceptable and coverage
areas are much smaller than for the main analog stream. Hence,
listening to HD-n (n>1) streams at home or at work MAY be OK (though
not necessarily), but listening in a moving vehicle is unlikely to be
acceptable unless you are very near the transmitter.
