Digital TV on channel 6 is no different than on any other channel.

I wonder if channel 6 doesn't offer the same bandwidth that other channels do in order to guard against interference at the bottom end of the "FM dial".
Aside from the fact that it abuts a substantially different bandwidth usage scheme that inhabits frequencies centered as little as 100KHz away? I'm inclined to believe that there had to be some reason that the FCC changed their minds about the Sacto PBS station.Digital TV on channel 6 is no different than on any other channel.

How much guard band is built into ATSC at the top of the 6MHz and is there reason to believe it may not have been sufficient?
So there's no evidence to support your claim that RF 6 is no different from any other channel and some that suggests that it might be capped based on how things turn out.
You made the unqualified claim that there is no difference between RF 6 and any other TV channel so the burden is on you to provide evidence that what you said is true. What little evidence you've offered has only hinted at supporting my claim that proximity to FM radio is likely an issue and something that the "owner" of RF 6 will suffer versus most other channels.I believe the burden of proof is on you.
I'm arguing that RF 6 became a blighted property with the advent of DTV. It is not about the fact that they're using the same modulation scheme but the likelihood that there just isn't as much you can do with the channel in terms of coverage area and perhaps even bandwidth as with most other channels. Those are the practical measures of value and the industry has shown its disdain by substantially vacating the channel for serious use.I'm arguing that a channel 6 DTV signal looks the same on a spectrum analyzer, uses the same amount of bandwidth and filtering, etc., as one on channel 5. I'm not arguing that FM interference in either direction isn't an issue (though I will say 73.525 vastly overstates the amount, being based on measurements made in the 70s).
Having to take remedial steps is like Charlie Brown picking the ugliest Christmas tree on the lot.Just that there's nothing unique to the signal itself that is different, like how stations on channel 14 have extra filtering to protect land mobile.
The gap shows how unrealistic their expectations were.
The expectations of whom? That's the magic of having one body make the goals and another making the policy to reach those goals. Where I work, we call it the "infinite capacity model" where Sales assumes that if they can sell it, it will be delivered on time. One of the side effects of assuming that everything is the same.The gap shows how unrealistic their expectations were.
Perhaps you'll recall what happened last time someone said "let them eat cake".Supply will be decreased and we'll see how much demand increases.

Clearly, not all TV channels have the same value because they can't all be utilized equally. These auctions are about establishing a value and if you believe that all channels are functionally identical, you're not exercising business sense or a being a conscientious student of Physics. You can do a cannon ball into the pool, but you have to mind that there can be no splashing on the deck around that pool when you do. Where's the equity in that?

The problems weren't hidden so much as the part of the FM radio band that RF 6 used was modulated as FM radio. Now that that's no longer an option, we see where all TV channels aren't so much the same.I would argue channel 6 has always been a problem, just that FM was much later in developing so a lot of the problems were hidden.
