The receiver reference signal CH7-13
|
CH7-13 instrument provides accurate time reception signal and the reference frequency transmitted radio State service time and frequency in Russia and ET-KB- ranges.
CH7-13 receiver systems used in reproduction and storage of scale time electronic clock systems, systems in real measurements, as well as for the comparison frequency crystal oscillators with a frequency reference of the State time and frequency of the USSR.
The device CH7-13 works with the L-shaped, pin and other antenna open . type
Provided control signal received via headphones
