New Wave Lengths


The changes in the wave lengths of the broadcasting stations of Australia, which were announced last February, will come into force on Sunday. About half the transmitters of Australia are affected by the re-allocation of channels, which, it is stated officially, has been made to allow for expansion of the services, and to provide a better distribution of wave lengths in districts where there are a

number of transmitters.

All the stations are still within the limits of the broadcasting band, which extends from 550 to 1500 kilocycles (200 metres to 545 metres). They will thus still be picked up between the two ends of the dial of a re- ceiver, but their relative positions within this band, and on the dials, have been altered, some having moved towards the lower end, and others towards the higher end. The changes will in no way affect the utility or efficiency of receivers beyond making it neces- sary to tune in the stations at other points on the dial, a factor which will render call sign markings, according to the old list, value- less and misleading. Dials marked with arbi- trary scales of numbers or with wave lengths of frequencies, or with the call signs in the new positions, will continue to be useful when the new settings for the stations are known.

With the exception of 2SM, all the Sydney stations will have their positions on the dial altered. The positions have been moved so that the intervals between them are larger, a condition which will enable old types of sets to be used with greater freedom from inter- station interference. 2FC will move farther up the dial to the point where 3AR is now received, about half-way between its present position and the upper end of the dial. 2BL will also move in the same direction and will be near the channel now used and to be used hy 5CL (Adelaide) and about half-way be- tween 2BL's old position and that at which 2FC is now picked up. 2GB will move up to not quite as far as 2BL's present position. 2UE will take the place now occupied by 2GB, and 2KY will assume a position which is a little above that of 2UE to-day. 2UW will go to a point now used by 2HD (Newcastle) and about one-third of the way between its present position and the old position of 2KY, and 2CH will move up two channels. 2SM

will remain where it is.

Many stations outside Sydney and beyond New South Wales have had their relative posi- tions altered, with the result that they will appear in a different order upon the dials of receivers. Of the interstate National stations 7ZL (Hobart) will drop down one channel; 3AR (Melbourne) moves down two channels, nearly to 5CK (Crystal Brook), which only moves down a trifle; 6WF (Perth), 5CL (Ade- laide), and 4RK (Rockhampton) are un- altered; 3LO (Melbourne) and 4QG (Bris- bane) practically change places; and 7NT (Tasmania) is unchanged.


In the New South Wales country districts, 2CO (Corowa) will come down to nearly 2FC's present position, and 2NC (Newcastle) will go one and a half channels above its present position. 2CA (Canberra), 2WG (Wagga), 2XN (Lismore), 2GN (Goulburn), 2WL (Wol- longong), 2KO (Newcastle), and 2AY (Al- bury) will be unaltered, or will only make minor alterations. Of the remainder, 2GF (Grafton) will move up one channel; 2HD (Newcastle) will move three channels; 2BH (Broken Hill) three channels away; 2MO (Gunnedah) four channels, and 2TM (Tam- worth) 19 channels.

In due course the following new stations will commerce transmitting in New South Wales: 2CR (Cumnock), 550kc; 2NR (Graf- ton), 700kc; 2LV (Inverell), 980kc; 2GZ (Orange), 990kc; 2AD (Armidale), 1080kc; 2KA (Katoomba), 1160kc; 2NZ (Narrabri), 1170kc; 2QN (Deniliquin), 1440kc; 2BE   (Bega), 1470kc; and another station in the southern districts on 1490kc. When these are in operation there will be 32 stations in the State, comprising six National, including four country regional units, and 26 commercial stations, of which 20 will be in country


It is impossible to give information as to where the various stations will appear on the dials of receivers after the change has been made, because dial recordings, unless they are shown in wave lengths or frequencies, depend upon the electrical characteristics of the apparatus. However, when the dial positions of some stations have been located, the points at which others will be received may be esti- mated by comparing their positions with those of known stations in the list of wave lengths and frequencies printed below. In case where dials are marked with scales of wave lengths or frequencies, the corresponding figures in the list may be used for tuning in the stations, FREQUENCY AND WAVE LENGTHS. The revised complete list of frequencies and wave lengths of all stations now operating and also those authorised to commence trans- missions is as follows:

The Director-General of Posts and Tele- graphs (Mr. H. P. Brown), in an address broadcast through a network of 66 stations throughout Australia last night, said that the change of wave lengths was the result of many months of intensive study. The primary ob- ject was to guarantee a service of high quality by each station in its respective area. Many thousands of listeners would benefit immedi- ately by the change, and would have less diffi- culty in selecting stations. They would be able to receive with greater facility and clarity. It was inevitable that some listeners would find cause for dissatisfaction — probably be- cause they would seek to listen to distant stations instead of the nearer stations pro- vided to give them service.
