I was under the impression the Radio Four carrier (198kHz ex 200kHz) was
the old "frequency standard of choice" in the UK, prior to GPS.
I don't recall anyone using MSF for much other than "what time is it, to
maybe the nearest second?".
Though I do recall John Becker of EPE magazine did a nifty little
millennium countdown clock using MSF as a base.
