Has been active since Feb 02, 2017.  Suspected Russian military, similar to The Pip, Squeaky Wheel, and Buzzer.  Voice has been heard also, but so far only test counts have been reported.  Digital signals have been noted, such as CIS 36-50 FSK, however those are probably not part of this transmission (I think absolutely not, but has not been proven yet), rather just co-channel stations.
