Hello giulipetra,
Radio Monique had a test on 6290 at 1216-1243* end.
Later, particularly around 1400, it was a different station, playing non-stop music for hours,
only identified on the pirate chat (as Pioneer Radio).
Then Radio Monique came back around 1600 UTC on 6330, then on 6320.
So are you sure you heard R. Monique at 14.00 UTC ?
