Why do we need to notify assignments under
Article 11 ?

• o Importance of notification.
• Inform others of the putting into operation of a
  new station.
• o Notification in planned bands.
• o Notification in non-planned bands and zones.
• o Simple Rule to know when to modify a Plan or
  when to notify Agreementing to Art. 11.

comments wrt proposed modifications?

• To permit all other possibly affected
  administrations to verify impact of the new
  station on their operations.
• GE84 and GE89 time-limits.
• GE75 time-limits?
