Hi,
    It looks like what you captured is Hampal. Another neat digital mode. 
Take a look at what a google search brings up.

Have fun

Greetings All,

While monitoring 20m late this afternoon using MixW - there appeared
on the waterfall a callsign........Yes that's correct ON THE WATERFALL
- spread out over about 1khz, almost like a picture.

At first I thought I was hallucinating, then a few minutes later it
rolled across [or rather down] again.this time complete with the MixW
'Butterfly' and I grabbed a screen print - which I have out at...

I was just wondering 'how did they do that?' as it clearly requires
multiple synchronised audio tones.
