In conditions of RF spectrum, the announce attention has been comparatively stable. Other than digital modulation, the AM, FM and TV spectrum didn't change ample until 1952, when the FCC updated 420MHz of UHF spectrum, well known as channels 14 thru 83. Until then, the rope was indifferent for army use, essentially radar.
In 1983, the FCC private an 84MHz inhibit of probably new UHF channels from 70 thru 83 from the TV announce band. These channels were indifferent for TV translators, and usually about 20 translators in this inhibit were ever licensed.
About 25 years later, 95MHz of the 700MHz spectrum containing UHF channels 52 thru 69 was widely separated in to 5 blocks, auctioned in what is well known as Auction 73 in 2008 and deserted by broadcasters in 2009. It resolved by arising 1091 licenses and raising a complete of $19 billion in winning bids. This is the outcome of spectrum expelled by the passing from one to another to DTV, moreover well known as the digital dividend. We do not especially know where that $19x1010 digital division went, and inside of the context of announce engineering, that situation is not relevant. What is applicable is how the spectrum division is administrated and its future belongings on DTV delivery and accepting in the future.
Oh, they would never do that
Until recently, the FCC rhythmical the made at home RF spectrum similar to the U.S. Army guards the bullion haven at Ft. Knox. Unfortunately, the FCC has remade the RF spectrum from national value to a essential commodity and diplomatic piata, still to be appreciated since its power and worth.
