The modified techniques and instrumental set to research temporary variations and statistical characteristics of HF signals on the line Moscow — Rostov

Results of updating of a hardware complex of the Rostov station intended to register the benchmark signals of a radio station of the exact time (RVM) are presented. It is applied modern ADC, allowing to register signals on intermediate frequency 500 kHz without phase ruptures. Synchronization from the basic highly stable generator allows measuring the Doppler shifts of signal frequency. Results of processing of the registered signals of the RVM station are given in a minimum of solar activity which illustrate expansion of informational content of measurements after modernization of the equipment of the Rostov station.
