Wireless Test

oe _ System of Relays STATION 2YA, Wellington, carried out a duplex telephony test last night with 2MH, Sydney, the experimental short-wave station of Amalgamated Wireless Australia, Lid., and also with W2XAF, Schnectady, New York. : At 11 pm., after 2YA had closed down, 2YA called up 2MH, Sydney. Mr. J. Ball officiated at the Wellington microphone and Mr. Farmer at 2M. 2YA expressed a wish to speak direct with W2XAF, Schnectady, and subsequently, after carrying out duplex telephony with Sydney, 2YA carried out a further test with New York. Music and speech were transmitted from Wellington. ; . Reception from 2ME was loud and clear, and as the test progressed reception in Sydney improved,. there being slight interference by static at the Sydney end. Promptly at 11 p.m. Sydney was heard calling "Hello, 2YA. Hello, 2YA. Here is Wellington calling us now Jack,’ and immediately afterwards Mr. Ball’s voice rang ‘out, "Are you there 2ME? We can hear you ¢calling us." Contact was thus made and the tests proceeded promptly. Reading and music from Wellington were clearly heard at Sydney, and shortly after ‘11 p.m. conditions at Sydney had improved. Some music was put on by 2YA to give the operators at Sydney time to make some adjustments. At 11.34 p.m. 2MH called up W2XAF and remarked that they had been testing with Wellington, and also stated that static was interfering with reception from New York. Conditions, however, kept on improving. "We'll keep contact with 2YA and we'll see you in another 10 minutes. You keep playing music, W2XAF, we'll change over to 2YA, Wellington, now," At this juncture, W6XN, Oakland, California, joined in the tests and made a quartet of ic, the latter station being in communication with W2XAF at New York. Immediately after this 2MW and W2XAF had another chat, and W6XN played some more music at the
