Test tones on BBC VHF FM stations.

I don't suppose there were many people listening to the BBC on VHF in the early hours of this morning, but I was surprised to hear programming interrupted without warning by a series of audio test tones. One of the tones was really low frequency, but came through well on my HiFi.
Was it a one off? Or do they do that often?
