With VHF, they usually did not use the channel next to a channel in use.

With UHF, the practice was to use one channel out of every six.

Although UHF was originally channels from 14 to 83, first channel 37 was taken 
away for radio astronomy use, and then channels 71 to 83 were taken away for 
use by other services - basically cell phones.
