I'm not sure if Pedro got a switch messed up or something.
At 0457Z I heard a short portion of the Cuban National Anthem...then another ..
Then an ENGLISH ID of Radio Havana Cuba for their evening broadcast...
Then dead air till 0500
Then into YL SS into 5 number groups
data packets joined in later.

It's hard to be a spy station if you ID....In ENGLISH!!

Mixing audio (RHC audio mixed with HM01/M08/V02, or numbers station audio during an RHC transmission), starting with the incorrect audio (as you described), and those kinds of things have always marked the Cuban spy numbers operation.  However it is not really a big deal, by NOT IDing they are not keeping their transmission locations a secret.

Such errors are, however, almost always amusing.

For anyone with the resources of a nation-state triangulating the transmission source of any HF signal is childs play if that is a goal of the nation-state.  Shoot, even at the hobby level it is pretty simple to do.  So hiding the transmission source location of any numbers / spy station is not important, who / where is sending the signal is only a secret to some hobbyist, not to any professional or non-professional but dedicated group of radio monitors.

The only things really “secret” about these transmissions are the message contents and exactly who is the intended recipient.  The source location cannot be secure.
