Local Repeaters

Nothing in the rules recognizes net’s, group’s or any individual’s special privilege to any specific frequency. Section 97.101(b) of the Rules states that “Each station licensee and each control operator must cooperate in selecting transmitting channels and in making the most effective use of the amateur service frequencies. No frequency will be assigned for the exclusive use of any station.” No one “owns” a frequency.

It’s good practice — and plain old common sense — for any operator, regardless of mode, to check to see if the frequency is in use prior to engaging operating. If you are there first, other operators should make an effort to protect you from interference to the extent possible, given that 100% interference-free operation is an unrealistic expectation in today’s congested bands
