Medium Wave Sunset In Europe

Looks like Mongolia never switched to the new frequencies when all of the LW/MW frequnecies were adjusted to make them all multiples of 9. I believe that was in 1978.

The 9 kHz spacing realignment was in the late 1970s for mediumwave, while longwave was a decade later. MW moved up 1 kHz while LW moved down 2 kHz. I have no idea why Mongolia never made the change.

Europe 1 (which targeted a French audience from a transmitter just on the German side of the border) was on 183 kHz (outside the 9 kHz plan) right up until it closed at the end of 2019. A lot of European car radios tune long wave (but not medium wave) in 1 kHz or 3 kHz increments, pretty much entirely for this reason.

There is a single MW station in north Africa which uses 10 kHz spacing, a Sahrawi station on 1550 kHz, broadcasting from a refugee settlement in far south-western Algeria. It was often detectable as a heterodyne whistle when you were tuned to 1548 at night, but has been audible with programming at night since all the UK 1548 stations went silent.
