e) Administrations may apply 12.5 kHz channel interleaving on a non-
interference basis to 25 kHz channels, in accordance with the most
recent version of Recommendation ITU-R M.1084,provided:
•
it shall not affect the 25 kHz channels of the present Appendix
maritime mobile distress and safety, automatic identification
system (AIS), and data exchange frequencies, especially the
channels 06, 13, 15, 16, 17, 70, AIS 1 and AIS 2, nor the technical
