Music peaking at S5+ with the usual UVB-76 beeps mixing during fades. Strong modulation with considerable dynamic compression. Direct reception here with the Kenwood R-2000 and 31' vertical.

Music off air around 0304z. Usual buzzer tones still present at ~S1 but readily copyable.

Here's a link to one of the copied images on 4625.  I don't know where it was copied from. 
https://ibb.co/FgJRyN4

Vice.com has an article about this interference, by a writer who does not know much about radio.  He claims SDRs are being used to transmit the images.

04:19 UTC - Making it into Toronto, Ontario Canada. Weak readable with some crackling / distortion in the audio;
04:22 UTC - Start of an SSTV image but the transmitter suddenly cut off.

S7 both on the loop and end-fed antennae.
