OK, pretty sure the mystery is solved...
Had been hearing this in the car with no way to peak or null the signal
to aid in identifying it. However, this morning had some time to play with
the CCrane 2E and was able to peak the Spanish speaking station in the null of WLS.
This led me to assume the station was Cuban as the sigs peaked in that direction.
The OTA program matched the online Radio Progreso
(they were playing some music this morning so that helped with the ID), so most likely it is AM 890
Chambas Cuba at 200kw power output.
