If there are many PMR users in your neighborhood, there is a chance that some of these users are operating on the same radio channel. To prevent that you receive signals from other users, sub-channels have been integrated. Two PMR radio's will only be able to communicate with each other when they are operating on the same radio channel and when they have selected exactly the same sub-channel.
