Re: Rural Areas and Signal Strength

None? Wow, you guys must have a ton of channels in PA...

But I agree that extending the FM radio spectrum probably wouldn't be too useful- I think we'd be better off breaking up the mega-radio conglomerates and allowing for more local stations (on the other hand, the two aren't mutually exclusive, and locally-owned stations aren't necessarily local or more interesting than mega-corp owned, so argh)

I suppose the same issues that make VHF-Lo bad for ATSC television would preclude the use of that spectrum for other digital purposes.

WPVI could easily go on one of the High VHF or UHF channels that are being given back after the changeover. Reemeber, right now each TV station has TWO channels-that will be reduced to one in Feb., freeing up a ton of channels. Also, remember that unlike NTSC stations (that required a vacant channel between two in the same city-which is why you had to have have channels 7,9,11 and 13 in the same city), with ATSC you can use adjacent channels, which means that in Philadelphia channels 7,9,11, and 13 will eventually be allotted (the spacing between DTV transmitters is about 3/4 that of NTSC, which means that these channels can be used in both NYC and Philadelphia).
Right now we're in a mixed mode, which means that NTSC channels are still being (over) protected.

I disagree about the FM band being extended. This spectrum is badly needed for several reasons. First, there's no distinct place to put digital radio (and remember, analog radio is almost 100 years old!). As a result we have the fatally flawed IBOC HD radio systen that's going nowhere. Second, the AM band is badly overcrowded-and by extending the FM band and moving many of the smaller AM stations over to it, the AM band will be able to once again be used for its primary advantage-powerful 50,000 watt AM stations covering a large swath of area. These stations are still badly needed-as an example look at the valuable service that WWL performed in New Orleans after Katrina (and may be performing again in a few days!).
Finally, the top of the present FM band is right against the aviation band. Powerful FM stations frequently interfere with aircraft communications. By extending the band downwards, it would be simple to eventually put a 1 mHz 'guard band' between the two services.

Don't you agree that having 30 stations occupying 30 Mhz of VHF spectrum in the entire USA is wasteful? I would much rather see channels 2,3 and 4 used for Hobbiest use and/or short to medium range (2-5 miles) wireless Internet. The equipment costs for this band would be dirt cheap and it would produce a whole new industry.

No, it can't. 7,11, and 13 are full power in New York and would result in interference with a full power in Philly. Channel 8 is in New Jersey, same problem. Channel 9 Allentown. Channel 10, Harrisburg, channel 12 Philadelphia. That's VHF-Hi.

All the UHF stations are also taken or precluded by interference issues; there's no room for a full-power station.

Remember we're losing 52-69.

which means that in Philadelphia channels 7,9,11, and 13 will eventually be allotted (the spacing between DTV transmitters is about 3/4 that of NTSC, which means that these channels can be used in both NYC and Philadelphia).
No, they cannot. There's also Baltimore to consider with those.
