I just returned back home from a trip and yes the signals are still there as of 10 minutes back. They can be heard on my websdr https://websdr.vu2tum.com/

These signals are being heard in VU as well. I have been seeing chatter on Whatsapp groups about these to the extent that 40m nets have shifted up. It will be interesting to geolocate the source of these signals based on a regional triangulation. Some folks are saying these are of China origin, others say they are from Israel or Iran.

Of course, what they decode into is yet another mystery at the moment.
