Bolshakovo transmitter was the most powerful medium-wave broadcasting station in the world, situated near Bolshakovo, Russia. It was used by Voice of Russia for broadcasting on the medium-wave frequencies 1116 kHz and 1386 kHz with a maximum transmitter power of 2.5 Megawatts. An SV4+4 ARRT-Antenna with eight guyed masts is installed. The masts, built in 1974, are 257 metres tall.
On November 1, 2007, Russia ceased using the frequency of 1386 kHz.
As of May 2008, it seems that the use of both mentioned frequencies has ceased, and the Bolshakovo station is probably no longer in use for medium-wave.
However, it is still listed as a shortwave station, and can clearly be heard in the UK transmitting in DRM mode on 6155 kHz between 15:00 UTC and 17:00 UTC on weekdays. This is despite it only apparently radiating 15 kW, and the fact that the UK is around 1700 km away from the transmitter and 50 - 60 degrees off the advertised beam direction.
