Wellington Radio Society

oe eee Monthly Méeting [tHE monthly general meeting of the Aniateur Radio Society of Wellington was held in-the Cambridge Terrace Congregational Schoolroom on Tuesday evening, February 11. Mr. J Owen occupied the chair, and there were about two dozen members present. . A letter was received from the N.Z. Association of Radiv Transmitters challenting thé Radio Society to a » ericket match. The idéa was commended as one calculated to promote a social feeling, but as the society was unable to muster a team it was reluctantly decided to explain the position to the radio transmitters and thahk them for their proposal. A communication was received from the District Radio Inspector in reply to a complaint regarding interference from dn electrical leakage in a certain area of Newtown. The ‘hon. secretary was requested to write the inspector to ascertain the résult of his investigations in the matter and what action he took. WING to a slight motor-ear breakdown, Mr. L. H. Wright, who was to déliver a lecture on "Servicing of Sets," was unable to attend, but in response to a teléphoned request from Mr. Wright, Mr. :Preston B. Billing kindly acted as his substitute. Mr. Billing stated that the servicing of A.C. séts-ivds an art in itself, and he related some of the problems he had to solve. He dealt with the differences between A.C. and battery valves. Mr. Billing also gave useful advice respecting "A" and "B" batteries. Owing to electrical leakages, Mr. Billing stated that it would generally be found that seven hours’ use of an "A" battery would require about 11 hotrs to recharge -at a rate which was the same as the discharging rate. Dampness on the top of a battety due to minute spraying ‘when charging, he said, was not a cause of leakage unless dust were mixed with the dampness. Mr. Billing stated that few audio transformérs would not 20, in time, owing to an electrolytic action between the Windings of the primary and the insulating material, He stressed the advisability of renewing the "C" battery every twelve months. Mr. Billing said that he had found that over half the troubles in A.C. sets which he had experienced were due to the valves. These A.C. valves, however, were now much improved, and were still improving. Mr. Billing anSwered several questions, and at the conclusion Was dccorded an enthusiastic vote of thanks.
