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.[1]

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,[2] 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.
