Dear Mr. Burch:

This refers to your letter of January 9, 1973, (6320-C), together with attachments and our earlier exchange of correspondence related to the coordination between our two Administrations of those frequencies included in Appendix 18 of the International Radio Regulations (Geneva 1967) for operations within the applicable coordination zone.

Having studied revised Attachment A and revised Attachment B, I am pleased to advise that we are in general agreement with those adjustments you have suggested and with the intent of the proposal as now set forth. The 1974 ITU Maritime Mobile Conference will probably make some adjustments to Appendix 18 and with this in mind it is important that we develop a joint plan in keeping with your views expressed in Note 6 of the revised Attachment A. Consequently, with regard to Notes 3–6 inclusive, it is considered that these arrangements would be of an interim nature pending the development of joint frequency plans to meet U.S. and Canadian Maritime Mobile frequency requirements along the Canada/U.S. borders.

Accordingly, arrangements implemented by our exchange of correspondence dated December 10, 1969 and , are hereby terminated, and your letter of together with this reply will constitute revised principles of understanding between our Administrations regarding the coordination of the frequencies listed in Appendix 18 of the ITU Radio Regulations.

This arrangement will be implemented by the Department on unless we hear otherwise from you in the meantime.

Yours sincerely,

ORIGINAL SIGNED BY

Dear Mr. Nixon:

This refers to the Department of Communications' letter 6110–9–3 (RAF) 6110–26 1165–46 dated , relating to the coordination between our two Administrations of those frequencies set forth in Appendix 18 of the International Radio Regulations (Geneva, 1967) when their use is contemplated within the applicable coordination zone.

The proposals, as given in Attachments A and B to the Department's letter, have been examined, and we find ourselves in general agreement. However, those proposals have been adjusted in part. A copy of both Revised Attachment A and Revised Attachment B is attached.

If you are able to concur with the foregoing, the Commission will adopt the plan in question effective upon receipt of your concurrence.

This letter was adopted by the Commission on .

By Direction of the Commission

Dean Burch
Chairman

Attachments: Revised A and Revised B


Revised Attachment A

Notes Pertaining to U.S./Canada Coordination of Maritime Mobile Frequencies Appearing in Appendix 18 of the International Radio Regulations Annexed to the International Telecommunication Convention

1. All ship station frequencies so indicated in Appendix 18 of the applicable International Radio Regulations may be exempted from coordination between Canada and the United States provided they are utilized in accordance with those conventional uses stated in Appendix 18.

2. Should a frequency designated in Appendix 18 as a ship station frequency be required for use other than on a vessel, Canada/U.S. coordination would be required before steps are taken to place such frequencies in use.

3. All new 25 kHz channels designated for use at coast stations (see frequencies in Attachment B numbers 60–88 inclusive) require coordination.

4. Other channels designated in Appendix 18 for coast station use (that is, those frequencies in Attachment B numbered 01–23 inclusive) with the exception of 156.800 MHz, require only an exchange of information between Canada and the U.S. However, if such frequencies are required for purposes other than those conventional uses stated in Appendix 18, coordination would be required.

5. The arrangement adopted by our exchange of letters dated (reference 6320–F) and (reference 5870–1 SRE–B) continues in effect with respect to Channels 24, 25, 26, 27 and 28.

6. It is anticipated that Channels 84, 85, 86, 87 and 88 may be the subject of presently planned further discussions between our two Administrations within the framework of VHF Maritime Mobile matters. Accordingly, in the current absence of a specific plan for these channels, and in the interest of planned use of the spectrum, successful coordination of proposed operations on either or both halves of each of the referenced channels is required prior to placing the proposed operation into service.
