The long-wave frequency used was 200 kilohertz (frequently referred to by the wavelength, 1,500 metres) until 1 February 1988[13] when it was changed to 198 kilohertz, and the power is currently 500 kilowatts
According to this, there are only three other longwave transmitting stations in the world at least as high-power as this station: one in each of Morocco, Algeria, and Poland. So I guess that it’s a pretty esoteric sort of hardware.
Hmm.
