North American Re-allocation

HE Wavana covference which wus concluded on December 138, 1937, adopted a drastic reallocation plan which will call for a shifting of the frequencies of a large number of the United States broadeasting stations. None of the United States stations will have to be deleted, however, and the frequency changes, in most cases, will be from only 10 to 30 kilocycles from the present frequencies. Most important to dxers are the facts that the broadcast band will be widened to 1600 k.c. and that the so-called "border" stations wilt have to leave the air or materially reduce their power. There are seven nations in the agreement, United States, Canada, Newfoundland, Mexico, Cuba, Haiti, and the Dominican Republic. The treaty will become effective one year after ratification by the four. major countries. The Channels. The 106 channels in the broadcast band are divided into three classesclear, regional and local. A clear channel is, briefly, oue on which the dominant station is able to provide service over 4 wide area, clear of objectionable interference within its primary service area and most of its secondary area. A regional channel is one on which several stations may work with power not in excess of 5000 watts. A. local channel is one on which several stations may operate with power not exceeding 250 watts. The 59 clear channels are designated as follows: 640, 650, 660, 670, 680, 690, 700, 710, 720, 730, 740, 750, 760, 779, 780, 800, 810, 820, 830, 840, 850, 860, $70, 880, 890, 900, 940, 990, 1000, 1010, 1020, 19380, 1040, 1050, 1060, 1070, 1080, 1090, 1100, 1110, 1120, 1130, 1140, 1160,

1170, 1180, 1190, 1200, 1210, 1220, 1500, 1510, 1520, 1580, 1540, 1550, 1560, 1570, and 1580. The 41 regional channels will be as follows: 550, 560, 570, 580, 590, 600, 610, 620, 680, 790, 910, 920, 930, 959, 960, 970, 980, 1150, 1250, 1260, 1270, 1280, 1290, 1800, 1310, 1820, 1380, 1859, 1360, 1370, 1880, 1890, 1410, 1420, 1430, 1440, 1460, 1470, 1480, 1590, and 1600. The six local channels will be: 1230, 1240, 1840, 1400, 1450, and 1490 k.c, The definitions given above, and

throughout this article, are not exact, but are sufficiently accurate for dxers’ purposes. The treaty provides for 59 clear channels, 41 regional channels and six local channels. These frequencies are apportioned among the seven nations as follows :- United States cocsscco-. 63 Canada eee sees oroeoooene 14 Cuba ....cecccssecccroon§ Y Dominican Republic .... lL Haiti see eweweweaewewGeeaooes 1 Mexico eeeoeeovr vs ove0edgeon ee 15 Newfoundland .ecceocoee 2 Stations Classified. All the broadcasting stations are divided into several classes and subclasses. Stations of Class I-A, Class 1-B and Class II will be permitted to work on clear channels. Class I-A stations will operate with a power of 50 kilowatts or more; their primary service area will be within the limits of the countries in which

they are located; and they will be free from objectionable interference from other stations on the same or adjacent channels, Class 1-B stations will employ power of not less than 10 kilowatts or more than 50 kilowatts, and their primary service areas will be free from objectionable interference from stations on the same or adjacent channels. A Class II station ig a "secondary" station which uses a clear channel. Stations in this class will use not less than 250 watts or more than 50 kilowatts, and whenever necessary a directional aerial or some other means must be provided to prevent interference with other stations. Regional stations are grouped, roughly, in Class III, and its sub-classes, and local stations are considered as being in Class IV. Assignment to Nations. Twenty-four United States stations of Classes I and II are shown in the tables which follow. ‘fhe remaining 39 Class I and II stations of this country will work on the clear channels of 640, 650, 660, 670, 680, 700. 710, 720, 750, 760, 770, 780, 820, 830, 840, 850, 870, 880, 890. 1020, 1030, 1040, 1100, 1120, 1160, 1180, 1200, 1210, 1500, 1510, 1520, and 15380 kilocycles.

Answers to Correspondents "Savaii" (Auckland): The informuation I have gives the address of CXA14 us Montevideo, Uruguay, but if it is relaying LR8 it would be best to address reports to LR8. I have not yet heard the station-224M.C. (Ashburton), "Dismal Desmond" (Christeliureh) : I, too, have heard the station which you mention, and when I heard if, on February 27, at 10.18 p.m., a man announced the call which sounded like, "OLF, Young. ‘The Town and Country Station.’ "-224M.C. (Ashburton). Identification Wanted Station on the 19-metre band, heard at 2.30 pm. on Tuesday, March 8 At the time I heard the station it was evidently broadcasling a concert, judging by the clapping, and this concluded at 3.15 p.m. Announcements in a foreign language were made between items by aman, and when the concert concluded another _man spoke in a foreign language. However, some English words were spoken, from which I gathered that he was speaking of the machine industry.-E.B, (Gisborne). Station on 3l-metre band, between COCQ and LRX, heard irregularly during the past two weeks until 6.30 p.m. or as late as 7.45 p.m. It has always been on phone with clear speech which seems to be Spanish. The other end of the line can be heard answering, and music is often heard.-R.M. (Auckland). enapermweeweseweweneewTwenetemeeeananrnpmpannrn se
