The BBC World Service will be making a special midwinter shortwave broadcast to Antarctica on Sunday 21 June at 2130 UTC. The broadcast is directed to members of the British Antarctic Survey, and will be on the following frequencies:
- 5950 kHz (from Rampisham, UK)
- 7295 kHz (from Rampisham, UK)
- 7360 kHz (from Ascension Island)

This appears to be an annual special, communicated only to those involved in the operation of the Antarctic bases, and who knows for how many years they already do it. I saw an operational memo for it some years ago, where it had also been specified that the broadcast is to be preceeded by ten minutes (or thereabouts) of interval signal.
Makes one wonder what other undocumented shortwave broadcasts may exist as well, still not being discovered by the editors of specialized publications. It appears that this category is not limited to all the political stuff (what DXing circles call “Clandestine”).
