Some FSK at around 50 baud is to be heard on the HF spectrum these days.
Almost none of it is the start-stop radioteletype that was much to be
heard 50 years ago. So I'm curious who is still using FSK and why?


There are still a few plaintext HF utility stations (the ones I can hear
most reliably are in Greece and Turkey, maritime weather forecasts and
news digests IIRC) but most are only active for a few hours each day.

45/170 shift RTTY and some SITOR B


Looks interesting.

News comes from satellites, not inky yellow paper.
