UNID Spanish numbers w/ data, 11635 khz., 0804 UTC, 6/1

[BoomboxDX]

Heard a woman giving number sequences in Spanish.  The voice sounded like the same Spanish voice I've heard on HF since the 1980's.  But the transmission was not the same as back then. 

Instead of just numbers, I heard one set of numbers, followed by a data burst, followed by another set of numbers, followed by another data burst, etc.

Low modulation on the signal, as well as mediocre propagation... SIO 241-2 (also some QRM from a broadcast in Chinese on 11640).

Hadn't heard this sort of 'hybrid' numbers broadcast before.

Did it sound like this?

You heard HM01, the Cuban number station. Pretty accurate schedule here:

Thanks for the info!  I had read about these 'hybrid' numbers broadcasts, but the last numbers Spanish broadcast I'd heard (last year) was the more 'traditional' one -- just the woman reading numbers after saying 'atencion'.  This sort is new to me.

This station (HM01) started being used sporadically about 8 or 9 months ago.  About 6 months ago it became the primary Cuban numbers station and the others from Cuba faded in use.  Today the traditional voice Cuban station (V02) and its sister Morse station (M08) have not been heard in a while.  The traditional digital Cuban station (SK01) has not been heard since shortly after HM01 appeared.

By the way, all Spanish language stations (there have been several, although as far as I know only 2 remain, V07 and V21) are not Cuban in origin.  For example V07 is a Spanish language numbers station with a voice that sounds very similar to the Cuban V02 and HM01 stations, but uses a totally different format than either of those.  However V07 is believed to be from Russian intel origins, and generally is believed to be transmitted from Russian installations in Europe or the Far East.
