Title: Improvements in or relating to radio transmitters
IPC: G01R23/00
Filed: 1960-06-16
Abstract: 895,608. Testing radio transmitters; automatic frequency-control systems. SIEMENS & HALSKE A.G. June 16, 1960 [June 16, 1959], No. 21216/60. Class 40(5). In a radio transmitter including a continuously tunable master oscillator, a resonant circuit which is permanently tuned to a frequency which is a function of a selected one of the transmitting frequencies is connected in the transmitter circuit so as to provide an indication when the master oscillator is correctly tuned to produce the selected transmitting frequency. The arrangement facilitates the lining up of the succeeding stages. As shown an incoming signal frequency modulates the 100 mc/s. output of an oscillator 2 via a modulator 1. A mixer 3 receives the output of the oscillator 2 together with 800 mc/s. oscillations from the tunable master oscillator 4 and produces an output frequency of 900 mc/s. which is amplified at 5 and 6 and supplied via a filter 7 to the aerial. A resonant circuit 10, constructed as a frequency standard, is coupled loosely to the filter 7 and the tuning of the circuit 10 is wobbled slightly at a low frequency, e.g. 50 c/s. from a source 11. A phase comparator 12 receives the wobble frequency from the source 11  . together with the rectified output of the circuit 10 and provides a control voltage which through a motor 15 corrects the tuning of the oscillator 4. The tuning controls of the units 4, 5, 6, 7 and 10 are mechanically linked to a common drive system, and preferably the transmitter is tunable to a number of spot frequencies which coincide with the points of correct alignment. A resonant circuit 9 tuned to a frequency of 800 mc/s. is coupled loosely to the output circuit of the master oscillator 4 and via a detector 16 controls an indicator 17. The oscillator 4 is tuned to give a maximum reading on the indicator 17 and the amplifiers 5, 6 and filter 7 are then individually tuned to provide maximum output in the aerial. Further indicating devices may be included e.g. indicator device 18 to enable amplifier 5 to be tuned independently of stages 6 and 7.
