• r Rio de Janeiro Agreement 1981
• List A and List B ( Res. 2 )
• Classes of station and protected contours
• Plan Stations not put into operation after
• 4 years (para.4.6.3) no longer considered.
• r Modifications to Plan RJ81
• RJ81 Special Sections
• Assignments in Part A for more than 180 days no
  longer protected

23
RJ81 Plan modification procedure
RJ81 Plan

• Coordination required with
• Co-channel stations (4.2.1)
• Adjacent channel stations up to 30 kHz (4.2.1)

24
RJ81 Plan modification procedure
RJ81 Plan

• Coordination between administrations based on
  interference field strength value on the
  protected countours of other assignments
• Protection of groundwave and/or skywave contours
  depending on station class
• Calculations according to chapter 4 of Annex 2

25
RJ81 Plan modification procedure
RJ81 Plan

• No agreement required (4.2.14) if modification
  implies
• No increase in ERP
• Site change lt 3km or lt5 dist to nearest border
• Site change max of 10km

26
Features of the RJ81 Plan modification procedure
RJ81 Plan

• Publication in Part A of a Special Section
• 60 days comment period
• BR reminders at 30 days
• BR calculates effect of proposed modification on
  pending modifications and vice versa
• No comment AGREEMENT
• Must request publication in Part B

Extracts from Frequently Asked Questions (FAQ)
RJ81 List B

• 1. What is list B?
• As indicated in Resolution 2 of the Agreement,
  the RJ81Plan consists of two separate lists
• List A which includes only the assignments
  whose caused and received interference are both
  accepted
• List B which includes all the assignments
  which are not included in List ABR calculates
  effect of proposed modification on pending
  modifications and vice versa

28
Extracts from Frequently Asked Questions (FAQ)
RJ81 List B

• 2. Why is there a need to resolve list B?
• Resolves 3 of Resolution 2 strongly urges
  administrations whose stations appear in List B
• to make every effort to resolve the
  incompatibilities relating to their stations as
  quickly as possible.

29
Extracts from Frequently Asked Questions (FAQ)
RJ81 List B

• 4. What are the benefits of resolving list B?
• Better electromagnetic compatibility in MF in
  Region 2 (less harmful interferences produced and
  received) and consequently easier introduction of
  new stations as well as modification of existing
  ones.
• Simplified Plan modification procedures could
  facilitate the possible introduction of digitally
  modulated emissions in the MF band in Region 2.

Extracts from Frequently Asked Questions (FAQ)
RJ81 List B

• 6. How many were there in List B at the end of
  the conference? How many have been resolved?
• 6.1 At the end of the conference there were a
  total of 1203 daytime entries and night-time
  entries in List B.
• 6.2 Today there are still 177 daytime entries
  and 735 night-time entries in List B

31
Extracts from Frequently Asked Questions (FAQ)
RJ81 List B

• 8. What is the regulatory mechanism for removing
  an assignment from List B?
• The procedure for moving assignments from List B
  to list A appears in ANNEX 2 to Resolution 2 of
  the RJ81 Final Acts. It involves actions by
• the Bureau (BR)
• the administration notifying a proposed move to
  List A (N. Adm)
• the administrations adversely affected (Aff.Adm).
  The procedure can be summarized in the table
  below

List B FAQ

Digital MF sound broadcasting in R2!
RJ81

• Special study by the BR. The results were
  published in Circular Letter CCRR/20 on 6
  September 2002 ?
• Conclusions
• The current regulatory provisions of the RJ81
  Agreement are rather inflexible and do not permit
  the introduction of digital modulation
• May be necessary to convene a short RRC for
  Region 2 countries, mandated to update the
  necessary administrative and technical parts of
  the Agreement.

35
Closing remarks
RJ81

• There is a way to facilitate possible
  introduction of digital MF sound broadcasting in
  R2.
• Participate in the resolution of List B!
