While speaking to an ex-WWII soldier, he mentioned to me that during Morse

He's certain it was some kind of signal, and has often tried to find out if
this was the case.
As it would make an interesting story for my programme I've been doing some
research into this - but to no avail. I've been onto Bletchley Park, and
the Royal Signals Museum, and across to France and the Signals' British
Liaision Officer there, but nothing has come up.

This almost sounds like a spy station, if you're implying that they played
Claire de Lune continuously and restarted it every five minutes. That
might be used as an easy way for the spy to find his station for the
time when his next encrypted message came through.

Then again, years back there was a series of frequencies on which someone
would continuously broadcast something called "Kiss Me Honey" or "Honey
Honey" (depending on which electronics magazine you read). That's all
they did. I also remember hearing a short ditty played on bagpipes that
was repeated continuously on several frequencies; it was nine or ten
seconds long, from memory. (I can still recall that tune if I try.)
