Aeroplane Radio

Telephony in N.Z. SUCCESSFUL ‘tests of radio tele phonie communication between an aeroplane and the’ ground were ¢arried out last week in Canterbury. When a Bristol Fighter flew ‘over Rakaia, more than forty miles from Wigram aerodrome, one of the occupants of the plane talked to members of the Air Force staff on land. The plane was equipped with a 30watt transmitter and a super-het re: ceiving set. .The ground transmitter was of about 100 watts. ‘The pilot of ae plane used in the tests was Flying @ifiicer BH, Olsen, N.Z.P.A.F., and his ‘Bassenger was Mr. B. Henderson, an engineer of the Radio Broadcasting Company. The instruments used were standard Royal Air Force equipment. The distance over which the signals were exchanged constitutes a record for New Zealand, as the Southern Cross in tests which it made while in the Dominion used Morse code, not telephony. As well as its wide use in commercial flying, radio plays a big part in modern military flying, both telephony and Morse being used.
