    Yup, looks like the Cuban Jammers. Looks like they're clobbering some FT8 in there as well?

    It's not the Cuban jammer, it almost sounds like PSK31 but in short bursts, and is definitely not PSK31. I'd say it's likely some sort of data transmission but I have no idea what it is.

    Sounds like some digital mode to me. FT4 maybe?

    It's a digital mode of some kind. I've heard it, because I tried it once. Can't remember which one.
