Holiday Mystery on 472 kHz

I decided to monitor the activity on 472 kHz tonight (630 meters). I fired up WSJT-X and saw that at least one station was in the holiday spirit.

Somehow, the transmitting station managed to send data that displayed “Ho Ho Ho” right in the waterfall, without any decoding.

It is nice to see that there are still surprises out there on the radio. They did seem to also transmit a callsign but it was not readable to me. Any ideas about who this Christmas elf is?
