KF1 FOLLOWING 2YA

CAREFUL TUNING NOW REQUIRED FOR LOCAL © | STATION a out at 2YA: "Complete arrangements having been made with the. Western Electric Company for the installation of one of its latest type crystal control panels at KFI which-is now making extensive changes in its present equipment, in order to incorporate the new unit. "With the new equipment in operation, KFIT’s present efficiency will be more than doubled. In addition to keeping the station on its proper wavelength, the new installation incorporates. a double modulation system which gives eighty per cent. modulation as contrasted to the thirty per cent. which KFI and other stations not so equipped now have. : . | "The crystal control equipment consists of a quartz plate which . it kept in oscillation at a. constant frequency. In order to maintain this frequency, the plates are enclosed in an insulated container’ which is kept at a uniform temperature by means of thermostatic control." | : 7 AWHILE careful listeners-in report a big improvement in both volume and clarity, as the result of crystal control being. installed ab 2YA, it would appear from other correspondence that it is necessary to remind listeners to be very careful when tuning in to 2YA, so aceurate and regular is the wavelength. They should-tune in to the . middle of the wave. If the tuning-in is ou either side there is a’. possibility that the quality will suffer. If the volume is too strong listeners ate advised not to detune to reduce’ the voiume, but to make reduction by suitable volume control, or by varying the antenna coupling. : oe .
