I am seeing this on my WSJT-X waterfall:
On 20m, just a short time ago. What am I seeing?
PS. Since posting the image, it has moved down the waterfall a bit, and only has about two thirds the bandwidth now.
An audio recording is infinitely more useful than a visual, but making a stab at it, I'd bet that it is Olivia. The bandwidth of the signal is approximately 500hz, and it appears to have 8 tones, so Olivia (or Contestia) running 8/500.
