Would love to know what licensing regime / category they are using for this. It definitely isn't ham, because that's non-commercial only. The fact that log period antennas are in use is interesting too - low gain but directional and useful across a broad frequency range - maybe some spread spectrum technology?

Wow, that would do it.

That one, WI2XER, has been heard, and seen on a spectrum analyzer.[1] They send their call sign in Morse code, send various test tones, and send what look like modem-type signals. 100 KW, so they will have no problem reaching Europe. Not much bandwidth, though, because they don't have enough spectrum space. Maybe a few hundred kilobits/second.

As a way to get info from markets faster, it's limited. You avoid some switching and path delays, but the data rate is slow, so it's only faster for short messages.

Probably licensed on several bands, as propagation conditions change quickly. They’d need to hop around, if not simultaneously transmitting on multiple bands.
