Pages: 202. Not illustrated. Chapters: Channel 1. Excerpt: In North
America, channel 1 is a former broadcast (over-the-air) television
channel. During the experimental era of TV operation Channel 1
moved all over the shortwave and lower VHF spectrum, settling at
44-50 MHz between 1937 and 1941 although visual and aural carrier
frequencies within the channel fluctuated with changes in overall
TV broadcast standards prior to the establishment of permanent
standards by the National Television Systems Committee. In the very
first post-experimental commercial TV allocations made by the
Federal Communications Commission (FCC) under the NTSC system on
July 1, 1941, Channel 1 was located at 50-56 MHz, with visual
carrier at 51.25 MHz and aural carrier at 55.75 MHz. At the same
time, the spectrum from 42 to 50 MHz was allocated to FM radio.
Several commercial and experimental stations operated on the 50-56
MHz Channel 1 between 1941 and 1946, including one station, WNBT in
New York, which had a full commercial operating license. In the
first postwar allocation which took effect in the spring of 1946
Channel 1 was moved back to 4450 MHz, with visual at 45.25 MHz and
aural at 49.75 MHz, and FM was moved to its current 88-108 MHz
band. But WNBT and all other existing stations were moved to other
channels, because the final Channel 1 was reserved for lower power
community stations covering a limited area. While a handful of
construction permits were issued for this final version of Channel
1, no station ever actually broadcast on it before it was taken out
of service in the late 1940s and the frequency band re-assigned to
public safety communications. When the FCC initially allocated
broadcast television frequencies, channel 1 was logically the first
channel. These U.S. TV stations originally broadcast on the 50-56
MHz channel 1 In 1940, the FCC rea...
