New 1YA and Interference

Statement hy Broadcasting Board In the "Radio Record" of Friday, November 23, @ paragraph in the Auckland notes made reference to the possibility .of interference being caused when the new 1YA transmitter comes on the air. This Statement has caused numerous inquiries to be made at the Broadcasting Board’s head office and the following statement, issued by the general manager of the New Zealand Broadcasting Board (Mr. FE. C. Hands), should set lis. teners’ minds at ease: ‘ The testing of the new transmitter will be done at,a time when IYA is off the air and will therefore cause no interference whatever. Due to the power of the station being 20 times higher than the present 1YA transmitter and the use of an efficient’ aerial system, there will certainly be a strong field in the vicinity of the transmitter, and listeners adjacent thereto-say within a mile-if their receivers are not modern, may have some difficulty in receiving other stations, but even here, by minor alterations to circuits and perhaps the use of wave traps, the difficulty can be overcome with little cost. With a modern receiver it will be possible, even in the transmitting station, to receive other New Zealand stations if they are using reasonable power. Listeners in Auckland city and most suburban areas will find that the new station will not cause any more interference with reception from abroad than they are experiencing at present, and in the case of those within a half mile of any existing station, interference will probably be less troublesome. One of the reasons for locating the station at its new site was to prevent the very strong field which necessarily exists in the immediate vicinity of a station from causing any large number of listeners interference when desiring to tune to stations adjacent in frequency to their local station. One great advantage that will be gained by the increased power, will be the over-riding of noises in many parts of the city, suburbs and beyond, by the signal strength of the transmitter. .
