A:AnswerYou can choose a "sub channel" for each channel but all that means is you will not hear other people using that channel. Be aware though that everyone else on that channel can still hear everything YOU say. There is not such thing as a "private channel." That's a pile of marketing baloney just like the claim these radios are useful up to 16 miles. More baloney. One mile on a good day, maybe a tad more with perfect conditions.
