Pshaw.  You are singularly misinformed on RF issues.

Here's the analog UHF taboos:
+/- 0
+/- 1
+/- 2
+/- 3
+/- 4
+/- 5
+ 7
- 14
- 15

That is, you have to protect existing channels by those channel offsets.
There's a hole every six channels.

Here's the digital UHF taboos

+/- 0
+/- 1
+/- 2

There are holes starting at three channels off.  And, the interference
protections are much lower than with analog.

And, we can see this in effect even now, as "for the most part" LPTV/tv
translator stations can now operate using the NEW taboos, and there are
many, many more channels now permitted for LPTV and tv translator use in or
near major cities than there were previously.

It will not be easy to find vacant channels in the compacted 
broadcast spectrum. We still need the white spaces to protect digital 
broadcasts, and we are squeezing existing broadcasters into a smaller 
container - limited use of VHF and no use of the 700-800 MHz spectrum.

So I would not expect the FCC to grant many new licenses in the 
remaining spectrum.
