This is no new signal. It's TECHSAT 1k2 PSK emergency beacon. See here:

Betreff: [amsat-bb] Re: Go32
These days GO-32 goes into a strange "emergency mode" where it
transmits something at 9600 (hard to decode)....when in this mode, it
makes constant noise...not just your normal 9600 baud "sssshhhhhh...."
sounds, either. The emergency mode sounds more like noise with
distinct "clicks" in it at regular intervals (1 sec or so?)
When out of emergency mode, it tends to send 9600 telemetry packets
every minute or (that's close...)
