2 APPLICATION OF THIS CODE OF PRACTICE
This code of practice covers the minimum performance considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics which may be required by a user.
It applies to any CTCSS operated in the land mobile services with radio equipment using amplitude or angle modulation where the purpose of the system is typically to facilitate channel sharing by more than one user or to enable base station equipments to be selectively operated in the “talk through” mode.
