Abstract
The receiving equipment (Fig. 16) consists of a FM receiver (Nems Clarke Model 1502 A) which is fed by a ten element vertically polarized Yagi antenna adapted to 150 Mc/s with ± 5 Mc/s bandwith. The directional characteristic of the antenna has a half angle of about 20 degrees in the horizontal plane. Because of its directional properties the antenna cannot receive a transmitter which is overhead of the station. In this case a single folded dipol was alternatively used. The LF (low frequency) output is directly fed to an amplifier and after being mixed with time marking signals spaced by one minute to a tape recorder.
