Dear Sir:

Co-ordination of Frequency Assignments in the Band 200-405 kc/s

Thank you for your letter of October 15, 1965 concerning a proposed informal arrangement between our Administrations for the co-ordination of frequencies for radiobeacons in the band 200-405 kc/s, applicable to certain areas of Canada and Greenland.

Regarding the co-ordination procedure outlined in my letter of September 11, 1964, this Administration agrees to all of the changes proposed in your letter of October 15, 1965. Since we have now reached agreement on the procedure to be followed, I would propose that this arrangement take effect on the date of receipt of this letter by your Administration. It is also proposed that the arrangement may be terminated when either Administration gives at least three months written notice to the other Administration.

As requested, I have enclosed a recapitulative list of Canadian radiobeacons located within the co-ordination zone.

I would like to receive confirmation that the final details outlined in this letter are satisfactory to your Administration.

Yours truly,

(F.G. Nixon),
Director,
Telecommunications and Electronics Branch

Co-ordination of Frequencies in the Band 200-405 kc/s

Ref. No.
5856-5
6801-439-1
(SRE(B))

Ref. date
11.9.64

Dear Sir,

With reference to your above letter concerning the agreement between our administrations as regards co-ordination of frequencies for radiobeacons in the frequency band 200-405 kc/s I have the honour to inform you that further consideration has been given to the definition of the co-ordination areas previously indicated.

I am now of opinion that it would be more convenient to let the co-ordination areas be determined by the service ranges of the radiobeacons to be co-ordinated rather than by the powers of the beacons, thus being in line with Article 7 of the Radio Regulations. I should therefore like to suggest that the following limits be applied:

  • Area a) Radiobeacons with a service range of 100 km
  • Area b) All radiobeacons
  • Area c) Radiobeacons with a service range of 350 km

As to the geographical limits proposed by you in our previous correspondence it is found that these areas cover the most relevant parts of your territory and, consequently, I can agree to these areas, but as far as area b) is concerned I should prefer to include all of the Canadian territory north of 75 degrees north lying east of 125 degrees west. This minor change appears logical in view of the close location of the Greenland and Canadian territories in the farthest north.

Far as Greenland is concerned, I am quite prepared to co-ordinate all radiobeacons in the band under consideration in the area west of 35 degrees west, and for the remaining Greenland territory I will co-ordinate all radiobeacons having a service range of 350 km, or more.

I agree that endeavours should be made to apply a protection ratio of at least 15 db between the desired and the undesired signal at the extremity of the service range of the desired aeronautical or maritime radiobeacon.

The Danish Administration agrees to the suggestion made by you that routine co-ordination of assignments under this agreement could be handled by air-mail correspondence between our two Administrations. We agree that the Administration with which co-ordination is sought should acknowledge receipt of the co-ordination data within 30 days, and within a further period of 60 days should provide substantive comments on the matter. In the event that the Administration with which co-ordination is sought does not reply within 90 days, that Administration shall be assumed to agree with the assignment in question.

Among the Danish radiobeacons in Greenland previously agreed upon in our correspondence, some changes have occurred in the call signs in order to align these with the last two letters of the ICAO-location-indicators. Therefore, I enclose a revised list of existing and planned radiobeacons in Greenland as agreed, the changed call signs being included in the list.

I should like to receive your comments on the above suggestions concerning the co-ordination areas. If the suggested classification of the co-ordination areas according to service ranges is acceptable to you, I should like to receive from you a recapitulated list of Canadian radiobeacons in the band 200-405 kc/s with the service ranges indicated.

Yours faithfully,

Barge Nielsen

Dear Sir:

Coordination of Frequency Assignments in the Band 200-405 kc/s

This refers to my letter of October 17, 1962 and your reply of July 21, 1964, reference  1.T. No. 6514 concerning a proposed arrangement between our two Administrations for the coordination of existing and planned radiobeacon assignments in the bands between 200 and 405 kc/s in adjacent areas of Canada and Greenland. We are pleased to note your agreement to the existing radiobeacon assignments in designated areas of northern Canada, as contained in the annex to our letter of October 17, 1962, also your concurrence in the protection ratio of 15 dB.

With regard to the limits of the coordination area proposed in my letter, these were considered adequate to provide good protection to radiobeacon assignments in the Arctic area. However, your suggestion to co-ordinate high power radiobeacons in a more distant area of Canada has considerable merit, assuming that your Administration is prepared to take equivalent action with respect to radiobeacons in Greenland.

Noting your agreement in principle to the limits of Area a) - (100 watts or more) and Area b) - (25 watts or more) suggested in my letter of October 17, 1962, I would like to propose a third coordination area south of 52 degrees North, to include the southern half of the Province of Quebec, all of New Brunswick and Newfoundland and the northern half of Nova Scotia, as follows:

Area c)
From the North Pole southward along meridian 55°W to its intersection with parallel 52°N, thence westward to its intersection with meridian 80°W, thence southward to its intersection with parallel 45°N, thence eastward to its intersection with meridian 52°W, thence northward along meridian 52°W to the North Pole.

In Area c) there are no existing Canadian radiobeacons in the bands between 200 and 405 kc/s having a power of 1000 watts or more. We propose to supply particulars of any planned Canadian radiobeacon assignments in the 200-405 kc/s band in Area c) where the peak power is 1000 watts or more.

In the matter of bi-lateral action, it would be helpful for us to have particulars of all radiobeacons in the band 200-405 kc/s in adjacent areas of Greenland, in order to assist our planning and to provide the best possible protection to your low-power stations. Therefore, it is suggested for your consideration, that coordination with this Administration be sought for all 200-405 kc/s radiobeacon assignments in Greenland west of meridian 35°W regardless of power, and for all such assignments east of meridian 35°W involving transmitter power of 1000 watts or more.

In carrying out coordination under this arrangement each Administration would recognize the sovereign right of the other to regulate its use of the radio spectrum, and each would not necessarily be bound by the views of the other. Nevertheless, in keeping with the spirit of international cooperation, this Administration is prepared to take immediate action to alleviate actual cases of interference to radiobeacons in Greenland in the 200-405 kc/s band caused by Canadian assignments, regardless of the power or location of the Canadian stations involved.

It is considered that routine coordination of assignments under this Arrangement could be handled by air mail correspondence between our two Administrations. It is suggested that the Administration with which coordination is sought should acknowledge receipt of the coordination data within 30 days, and within a further period of 60 days should provide substantive comments on the matter. In the event that the Administration with which coordination is sought does not reply within 90 days, that Administration shall be assumed to agree with the assignment in question.

I would appreciate receiving your early comments on the contents of this letter, and any other suggestions regarding our proposed coordination arrangement.

Yours truly,

(F.G. Nixon)

Dear Sir:

I would refer to your letter of April 12, 1962, reference 1.T. No. 2992, concerning interference to the maritime radiobeacon Koak-cerne (Greenland) operating on 314 kc/s with a service range of 50 n.m., caused by Canadian radiobeacon FY at Frobisher Bay, operating on 315 kc/s with a service range of 200 n.m. It is believed that this problem will be satisfactorily resolved by our proposal to change Frobisher Bay radiobeacon FY from 315 kc/s to 206 kc/s, conveyed to you in our telegram of September 5, 1962, and agreed to in your telegram of September 10, 1962.

I regret the delay in replying to this remaining paragraphs of your letter, which propose an administrative arrangement between our two Administrations for the co-ordination of existing and planned radiobeacon frequency assignments in the bands between 200 and 405 kc/s for adjacent areas of northern Canada and Greenland. I thank you for the particulars of planned and existing radiobeacons (200-405 kc/s) in Greenland, contained in Annexes 1 and 2 of your letter. These particulars have been examined in relation to existing and planned radiobeacons in northern Canada and we anticipate no interference from the radiobeacons in question.

In the matter of a continuing arrangement between our two Administrations for the co-ordination of frequency assignments for radiobeacons in the bands between 200 and 405 kc/s, it is believed that such an arrangement would be to our mutual advantage and could be brought into effect by a continuation of this exchange of correspondence. This matter has been studied in some detail and, noting that you have supplied particulars of existing and proposed radiobeacons in Greenland, I now propose to supply similar details for adjacent areas of northern Canada, as follows:

Area a)
From the North Pole southward along meridian 125°W to its intersection with the Arctic Circle, thence eastward along the Arctic Circle to its intersection with 80°W, thence southward along meridian 80°W to its intersection with parallel 52°W, thence eastward along parallel 52°W to its intersection with 55°W, thence northward along meridian 55°W to the North Pole.
Area b)
From the North Pole southward along meridian 70°W to its intersection with parallel 60°W, thence eastward along parallel 60°N to its intersection with 55°W, thence northward along meridian 55°W to the North Pole.

In the case of Area a), we propose to supply particulars of existing and planned radiobeacons within the band 200-405 kc/s having a peak envelope power (Pp), as defined in Article 1, No. 95 of the Geneva Radio Regulations, of 100 watts or more; and in the case of Area b), those having a Pp of 25 watts or more.

A list of existing radiobeacons having the specified powers within the designated areas is contained in the Annex to this letter. The list is complete as of this date and we propose to provide your Administration with similar details of any planned radiobeacon assignments in these areas, on a continuing basis, in order to effect co-ordination of such assignments prior to their actual implementation. It is assumed that details of planned radiobeacons in Greenland will also be provided by your Administration on a continuing basis, for co-ordination purposes. In carrying our such co-ordination, each country would recognize the sovereign right of the other country to regulate its use of radio frequencies, and each would not necessarily be bound by the views of the other.

In Canada, the daylight service range of aeronautical radiobeacons is based on a minimum field strength of 70 micovolts per meter, in accordance with the recommendations of the International Civil Aviation Organization. In the case of maritime radiobeacons, the daylight service range is based on a minimum field strength of 50 microvolts per meter, pursuant to Article 7 No. 461 of the ITU Radio Regulations (Geneva, 1959). With regard to protection ratios, the Geneva Radio Regulations (Article 7 No. 433) provide, in the case of aeronautical radiobeacons, a ratio of a least 10 dB for each beacon throughout its service area. In Canada, we endeavour to provide a protection ratio of at least 15 dB between the undesired and desired signal at the extremity of the service range of the desired signal, for all aeronautical and maritime beacons. Perhaps your Administration could agree to these values, for frequency co-ordination purposes.

The foregoing tentative proposals are submitted as a basis for further discussion. We are prepared to give careful consideration to the exchange of information additional to that contained in the Annex to this letter for radiobeacons operating in the bands between 200 and 405 kc/s, including any suggestions you may have as to amended power levels, co-ordination areas, interference ratios, etc. I would appreciate receiving your comments on this matter at your convenience.

Yours truly,
