BBC World Service 1779Khz 2130 03-Apr

Hi
New to site and SWL but been lurking as a guest for a couple of months. Not sure if this should be in this topic or MW broadcast section.

I picked up the BBC world service on 1779Khz last night with a strong clear signal in my QTH (S. London). On a quick google I haven't found any reference to the BBC using that frequency, online sources only seem to list Stockholm Radio. There is one Youtube post with a recording.

Does anybody know was this a genuine BBC broadcast (maybe a test?), somebody relaying the BBC or some spurious/induced signal?

Thanks
