Transmitted on the following frequencies:
The transmission follows an hourly schedule and is transmitted in different
hours by different stations across the old Soviet Union. At different points
in the schedule, a different signal can be heard. At first just a carrier;
then the callsign of the station in CW; next a carrier with 40Hz modulation,
double sideband; a 10pps time signal and finally silence. For the exact
schedule refer to http://www.vlf.it/russianvlf/russianvlf.htm.
