RADIO TELEPHONY
HOLLAND TO AUSTRALIA CONVERSATIONS FACTORS IN SUCCESS (Australian and N.Z. Press Association) LONDON, Monday. In view of the backwardness of British attempts to establish wireless telephony with Australia the Australian and New Zealand Press Association invited Dr. Koomans, chief of the Dutch radio laboratory, to indicate the factors of success in the repeated Dutch conversations with Java and Sydney. Dr. Koomans said he used directional beam with wave-lengths of 18.4 and 38.8 metres and 32 kilowatts power. Recently he had an outstanding success in the daytime with a new transmitter on 16.3 metres. There was no fading on any wavelengths and no atmospherics on the two lower ones. He admitted that it is virtually impossible for the Dutch at night to get efficient communication.
