I heard one of these for the first time yesterday morning! It was about 5:20 am ET, at 7890 khz. It was a machine with a woman's voice, and was saying several 5-number groups in Spanish. Either the whole broadcast repeated, or several of the number blocks were the same. I listened until about 5:35, but by that time a news broadcast started bleeding in quite a bit and I had to get to bed.
