[time-nuts] Lightsquared goes Global...

[Robert LaJeunesse]

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.

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.
