The three IARUregional organizations develop band plansto offer guidance to radio amateurs on how the different operating interests and modes of emission can be best accommodated in the limited spectrum available. Observing band plans is good amateur operating practice. In most cases observance is voluntary although some administrations incorporate the band plan for their egion into national regulations. Also, many contest sponsors require that competitors adhere to band plans.

To the extent possible, the IARU R2 band planis harmonized this with those of the other regions. It is suggested that Member Societies, in coordination with the authorities, incorporate it in their regulations and promote it widely with their radio amateur communities. Of course, if a band plan conflicts with national regulations the national regulations must be observed.
