Saudi (was UNID) 900kHz.
Now that sunset times are so early, using the Cyprus KiwiSDR we can observe the sign on times of the 900 kHz carrier which has been identified as Saudi’s Riyadh channel. Carrier starts daily at 1427 UTC and ends at 2257. A 60 Hz (not 50 Hz) sideband is present on some days. As noted by others, program audio level is low and often undetectable.
We might assume that this transmission is directed towards countries beyond Saudi’s northwest border. Hence the strong signal in Europe after dark.
