MEASURES TO SECURE SECRECY
IMPROVING TRANS-ATLANTIC TRANS MISSION.
London, January 17
Announcing the erection of a supplementary station at Dundee to ensure greater clarity of trans-Atlantic telephony, Mr Purvis, Post Office Engineer-in-Chief, says he never claimed to guarantee secrecy, but special efforts were being made in that direction. Even on the beam such a wide “track” was required that signals could easily be read. Regular users of telephony should use codewords and phrases, but he hoped to devise means of cutting up words into fragments at the transmitting point and piercing them together again at the receiving end, thus baffling interception en route. —A. and N.Z.
