RADIO NOTES

(By “Transformer.”) The attempt made by station 2YA last Sunday to relay the special American broadcast programme for tlio Byrd Expedition met with considerable success, the American announcer’s words to each member of the expedition being particularly clear. A low-power broadcast station which is heard by many North Island listeners is 2ZE Eketahuna, owned and operated by Mr J. B. Allen. The wave-length is 248 metres. 2ZE operates on Wednesdays from 5.30 p.m. till 8 p.m., from 1 p.m. to 2 p.m. on Thursdays and on Sundays from 4.30 p.m. till 6 p.m. News comes from Sydney that the new transmitting plant for 2BL is now under construction. This will give 2BL an aerial power equal to that of 2YA, namely, 5000 watts, which means an increase of nearly three times the present power of that station.

So great have been the sales of radios and radio apparatus in America that many gramophone and piano manufacturers in the States are now producing radio sots. When ,a 6-volt A battery has just been received from the charging station it should read approximately 6.3 volts, whilo a 4-volt battery should show about 4.2. The air has lately been full of politics from Australia. 4QU and 2FC often being heard broadcasting political speeches. “Transformer” has noticed lately that several low-power stations such as 2YB and 2ZL have been coming in with much greater volume than before. 7ZL Hobart is another station which lias become much louder and clearer lately.

On Saturday evening a bright and entertaining programme will be presented from 2YA. The orchestral items "Will include tho overture “Chu Chin Chow,” two novelty instrumental numbers, “Haunting Humouresquc” and “Mailu,” a violin solo, “Mighty Lak a Rose,” by Mr W. Haydock, and a (lute and clarionet duet by Messrs Brown and Langtry, “Flower of Mexico,” and several dance novelties. Humour will bo provided by “Ajax” of “Ajax and Bejax,” who will relate some experiences of his Hebrew friend “Cohen” of telephone fame. Novelty instrumental items will bo given by Mr L. Beavis on his steel guitar. On Sunday night the Port Nicholson Silver Band will give an after church recital in Grand Opera House.

RADIO BEACONS FOR AIRCRAFT. (Continued from last week.)

The course marked by the radio beacon transmitter is only from degrees to 5 degrees wide. If the pilot flies out cf this area, as he may do in older to avoid a storm, lie will, of course, know whether he flies to the left or right of it and will watch his compass and so know the general direction of flight. When he wishes to return to the course, he steers in the general direction of it and keeps on until the white lines on the indicator show that he is back again between tho edges of the beam from tho radio-beacon transmitter. Whore the course between two airports is 200 or more miles apart in a straight lino, radio marker' beacons may be found about every 25 miles apart. An aeroplane that flies regularly on such courses will have an indicator that shows an' additional white line. This line may not remain steady like the two others, but may appear and disappear like the flashing light of a lighthouse. Its signals correspond with those of the beacon light in tho same locality. Tho pilot seeing the signal again and again on the indicator can tell by a glance at his map exactly where ho is. By noting his time of arrival at one marker beacon after another, ho can tell what speed he' is making and how much the wind is helping or hindering him. When the ’plane reaches its destination and turns back towards the beacon that has guided it, the radio-beacon indicator on tho instrument board is turned end for end. Olio end is marked “From Beacon” and the other end “To Beacon” so that no mistakes will bo made.

Besides keeping the ’plane on its course, and helping tile pilot to find the courso if he is not on it, the radio-beacon receiver also brings to the pilot information concerning the weather ahead. Ho may, if ho chooses, or if he is ordered to do so, wear a helmet in which ear-phones arc installed. Ho carries a schedule showing the times at which weather reports and storm warnings are to be sent by radio telephone from tho radio-beacons or other stations. At the appointed time he turns a knob on tho instrument board, or if the radio-receiver is within easy reach ho turns a knob on it. In either easo the knob is stopped at the proper place for bringing in tho weather report. There is no fishing for stations. When he has heard the weather report and any other information that is being transmitted for the use of pilots in the air, he turns tho knob back to its original position. In early experiments with aircraft radio beacons, signals from the beacons were received through ear-phones instead of with tho visual indicators now in use, but this method was discarded, as continual listening was too hard on tho pilot. The reason for the action of the white lines on the face of the indicator is easy to understand. The beacon transmitter sends out two radio ■ beams like invisible fences on cither side of an invisible road. When the ’plane steers too close to tho “fence” at the right the vibrating reed on that side becomes excited, vibrates more strongly, and makes its white lino longer. The radio beacon indicator is one of tho final instruments needed on the instrument board to make flying safe and to make tho aeroplane a dependable means of transportation.
