I'm sure this is unrelated, but I found it on Wikipedia:
In Italy 375-line television transmissions were undertaken by Arturo
Castellani ^[8]
<https://en.wikipedia.org/wiki/375-line_television_system#cite_note-8>

^[10]
<https://en.wikipedia.org/wiki/375-line_television_system#cite_note-10>
in 1937,^[11]
<https://en.wikipedia.org/wiki/375-line_television_system#cite_note-11>
with daily broadcasts from Rome <https://en.wikipedia.org/wiki/Rome>,
between 6pm and 9:30pm on 6.9 meters (43.45 MHz) with a power of 2 kW.
I wonder if someone revived an old transmitter and is using it for music
or Muzak.

Not it doesn’t correspond with any local stations. I’m thinking in
could be a Muzak style service in a foreign country.

Since it is music, do you concurrently hear it on any commercial
broadcast frequency?
Also could it be a harmonic or derived from mixing with an
intermediate frequency?
