Might be worth a read of some of Charlie Rhodes' columns at TV Technology. The latest is "Can Terrestrial Broadcasting and GPS Co-exist in Adjoining Spectrum?" and is at http://www.tvtechnology.com/article/122176
Over the years Charlie has presented what seems IMHO to be valid reasons why TV white spaces - aka guardbands - exist and that terrestrial TV needs them. Same applies for GPS and LS. I'd at least agree that the need for white spaces is one main reason why "Terrestrial TV simply cannot use all the bandwidth it is allotted". Of course, my meaning of "use" here is that of "occupy". I think Mr. Rhodes would contend even un-occupied spectrum is in use...

Terrestrial TV simply cannot use all the bandwidth it is allotted. Spectrum has been whittled away at least twice. Once to create T-band. Again a little bit when HDTV was rolled out. The band needs to be trimmed with a sawzall. -----Original Message----- From: paul swed <paulsw...@gmail.com> Date: Thu, 30 Jun 2011 15:09:06 To: <li...@lazygranch.com>; Discussion of precise time and frequency measurement<time-nuts@febo.com> Subject: Re: [time-nuts] Lightsquared goes Global... Scratching the ole head. "TVs a waste"? A comment on the editorial content perhaps? But then how does any of that really have anything to do with Time-nuts. Regards Paul.
