Well, the Globe doesn't give this claim much ink. It may have been a story
they missed, or they may not have seen the significance of it, or maybe it
didn't happen (what a shock!). But for what it's worth, here is the one
mention I was able to find, from the Boston Globe, 29 August 1985, p. 62:
WGBH-FM (89.7) is co-producing the Pittsburgh Symphony, under the direction
of Lorin Maazel, live from the Salzburg Festival at 1:30 p.m. Saturday. It
will mark the first American orchestra to be broadcast live as well as the
first live digital transmission from the Austrian festival. The concert
includes Benjamin Britten's "Sinfonia da Requiem," Igor Stravinsky's
"Symphony in Three Movements" and Cesar Franck's Symphony in D Minor.
According to Anita McFadden, WGBH Radio technical director, "After being
digitally encoded in Austria, the program will be sent via international
satellites directly to Boston, where the signal will be decoded and
distributed over the National Public Radio domestic satellite system to the
participating radio stat ions throughout the United States."
And in more technology news, although about TV as well as radio signals,
this is from the Boston Globe, 5 October 1987:
ASK THE GLOBE
Q. I've heard there is only one station in the United States which
broadcasts a PCM (pulse code modulation) signal and that it is in Boston.
What station is it? -- A.M., Brookline
A. Lynn DuVal of WGBH tells us WGBX (Channel 44) is indeed the only station
in the country to carry the signal and has been doing so since Aug. 1,
1986, under special license from the Federal Communications Commission. Ch.
44, she explains, takes a raw radio signal, feeds it through a pulse code
modulator and encodes the signal into "square snow," or digital audio
(stereo), which cannot be heard on regular receivers. The station then
combines the stereo signal with a regular monaural radio signal. About 100
persons in the Ch. 44 broadcast area have pulse-code modulators. When they
receive a visual signal on a videotape, to which they have connected their
PCMs, they can decode the signal into clear, pure stereo audio, free from
the usual hiss and other distractions, as it was originally fed into the
Ch. 44 PCM. PCM broadcasts are aired weekdays from 11 p.m. to 11 a.m. and
Saturdays and Sundays from 11 p.m. to 8 a.m. If the Massachusetts House is
in session, PCM broadcasts end whenever Ch. 44 begins live coverage of
House activities.
