- In general, the traditional broadcast spectrum is full. It may be
- "fuller" in your part of the country than you think.
- For example, the fact that your TV doesn't pick up a strong station on
- every channel is not sufficient to say the spectrum in your area isn't
- full because, by law, you can't have transmitters on adjacent
- TV frequencies in the same area (practical TV filters don't have
- sufficiently sharp frequency drop-offs to reject an adjacent channel).
- In other words, in any city, almost half of the channels will show
- nothing but snow with a modest antenna. There are exceptions because
- some adjacent channels are not frequency-adjacent.
-
- There are a number of other reasons for frequencies to be controlled
- even when the spectrum appears to be clear to the casual observer,
- including reasons involving technical and national interests.
