Sometime in the last week what has been dubbed "The Alarm" appeared at 4020kHz, and has been going continuously since. A sample was captured here: https://youtu.be/bV7X07-jSVQ
A few days after it appeared, a test count in Russian was recorded: Vocaroo | Voice message
So far, it appears to be coming from one of the same Russian military transmitter sites that UVB-76 uses.
