Channel 37
Channel 37 (608-614 MHz) is/was reserved for radio astronomy research conducted by the University of Illinois’s Vermilion River Observatory (40.0611°, -87.5511°) near Danville, IL. From 1959 to 1970 the observatory used a 400 foot wide by 600 foot long linear parabolic radio telescope to focus on 3 frequencies, 410, 610 and 1400 MHz. Channel 37 transmissions within 600 miles of the observatory would interfere with the 610 MHz frequency. In 1963 the FCC reserved channel 37 for radio astronomy, there were no TV stations using the channel at that time. The Observatory closed in 1981 and was decommissioned in 1984, but RF channel 37 remains reserved.

Spectrum History
In the 1950's there were very few TV UHF broadcast. In the 1960's the number of UHF broadcast started increasing, but never came close to the number of VHF stations until digital broadcast started in 2009. Today UHF stations far outnumber VHF stations.

The Television allocated spectrum has been reduced over the years.
