At the same time, the IFRB shall publish in a special section of its weekly circular the information sent pursuant to 4.2.2 and 4.2.3 listing the names of the administrations concerned. 4.2.6. The IFRB shall send the administrations listed in the special section of its weekly circular a telegram informing them of the publication and shall forward the result of its calculations to them. 4.2.7. An administration which considers itself entitled to appear on the list of administrations whose frequency assignments have been considered to be adversely affected according to 4.2.10 may, within 60 days from the date of publication, request the IFRB to include it in that list. Also, a copy of the request shall be sent to the administration proposing the modification to the Plan, together with the relevant technical reasons. 4.2.8.

Any assignment in conformity with the Agreement shall be considered as adversely affected when appropriate calculations based on Annex 2 indicate that objectionable interference occurs as a result of a proposed modification to the Plan. 4.2.11.

Should an administration listed in the special section consider that a proposed modification to the Plan is unacceptable, it shall communicate its reasons to the administration seeking agreement within 60 days from the date of publication of the relevant IFRB weekly circular. It may also offer any information or suggestions it deems useful for bringing about a satisfactory solution to the problem. The administration seeking agreement shall endeavour to adapt its requirements as far as possible, having regard to any comments received. 4.2.13. Comments from administrations on the information published in accordance with the provisions of 4.2.5 shall be sent either directly to the administration that is proposing the change or through the IFRB. In all cases, the IFRB must be informed. 4.2.14. The agreement referred to in paragraph 4.2.1 is not required for a proposed change in the characteristics of an assignment in conformity with the Agreement provided that it entails no increase in the effective monopole radiated power in any direction and if a change in the site of the station is involved this change is limited to 3 km or to 5% of the distance to the nearest point on the border of a neighbouring country up to a maximum of 10 km. The move is referred to the site first registered in the Plan or subsequently registered in the Plan as a result of the application of the provisions of paragraph 4.2.1. In any event the move shall not result in a groundwave contour overlap prohibited under paragraph 4.10.4.2 of Annex 2 to the Agreement. However, no protection will be required beyond the level of protection which was already accepted before the proposed move. If the IFRB finds that the above conditions are met, it shall enter the proposed modification in the Plan and publish the relevant information in a special section of the weekly circular.

If, in seeking agreement, an administration makes changes in its proposal which result in an increase in the effective monopole radiated power in any direction with respect to the initial proposal, it shall again apply the provisions of 4.2.1 and the consequent procedure. 4.2.18. If no comments have been received on expiry of the period specified in 4.2.16 or if an agreement has been reached with the administrations that submitted comments, the administration proposing the modification shall inform the IFRB of the final characteristics of the assignment and the names of the administrations with which agreement has been reached. 4.2.19.

The IFRB shall examine the proposed modification to the Plan in order to determine the probability of objectionable interference in the channels of the band. If its finding is unfavourable, the IFRB shall select the channel which offers the best solution and accordingly inform the administration proposing the modification and any other administration whose assignments in conformity with the Agreement may be adversely affected. 4.3.4. In order to guarantee the integrity of the technical criteria on which the Plan is based, the IFRB shall make recommendations to the administration proposing the modification for reducing or eliminating the objectionable interference. In any case, these recommendations should cover the following technical solutions: - modification of an assignment entered in the Plan in the name of the administration proposing the modification but not yet put into service; - the use of directional antennas, reduction of the power or change in the site of the transmitter. 4.3.5. The administration proposing the modification to the Plan should do all in its power to eliminate any objectionable interference or reduce it to a minimum by adopting the technical solution suggested by the IFRB. 4.3.6. If the administration whose assignments inconformity with the Agreement may be adversely affected finds that it can accept the interference caused to those assignments as a result of the technical solution recommended by the IFRB, it shall so inform the Board within 60 days.

The IFRB shall publish this information in a special section of its weekly circular. 4.3.8. A note in the Plan shall indicate that in the examination of proposed modifications to the Plan which may subsequently be submitted, the relevant calculations shall be made with reference to the initial usable field strength value of the other assignments in the same channel, without the assignment in question being considered. 4.4 Settlement of disputes If, after application of the procedure described in this Article, the administrations concerned are unable to reach agreement, they may resort to the procedure established in Article 50 of the Convention. The administrations also may apply, by common agreement, the Optional Additional Protocol to the Convention. 4.5 Cancellation of an assignment When an administration decides to cancel an assignment in conformity with the Agreement, it shall immediately notify the IFRB, which shall publish the cancellation in a special section of its weekly circular. 4.6 Assignments recorded in the Plan but not brought into service 4.6.1.

In cases where the IFRB finds that not objectionable interference will be caused to such stations, it shall delete the symbol. The administration shall notify the assignment in accordance with Article 5 of the Agreement.
