RE: Aircraft channel question
Different areas will tend have different conditions. Frequencies that work in one area may be "bad" in another. Here, we've had a pager near channel 50 that just "blew away" all efforts to use channel 50 and 1 or 2 adjacent channels. Other channels are similarly affected. That's why there are 50 channels in the 72 MHz band. If a channel is bad, you can go to another one.
If you are close to a channel 4 TV transmitter, then you may have difficulties with all of the 72 MHz frequencies. It depends upon how close you are to the TV4 transmitter, and how powerful that particular transmitter happens to be. In most areas, though, it's a non-issue.

RE: Aircraft channel question
I forget the exact math but the audio portion of the channel 4 broadcast mixes with the channel 20 signal to cause interference near or at a couple other frequencies.
As previously stated its pretty much a non issue in the days of dual conversion recievers and modern radio technology unless you are flying next to the stations antenna.
