Most powerful operational longwave transmitter

The Taldom transmitter in Moscow Oblast, Russia, is the most powerful signal power for longwave radio currently in operation. Built in the 1970s, it transmits on two longwave frequencies – on 153 kHz with 300 kW and on 261 kHz with a power of 2500 kW. The site possesses two longwave transmission aerial systems: a single 257-metre-tall mast radiator for 153 kHz, and a ring antenna system consisting of five masts arranged in a circle around a 275-metre-high mast for 261 kHz. The transmitter currently broadcasts "The Voice of Russia" radio station programmes.
