181059 MHz USB Unknown signal

181059 MHz USB
I have run across this signal several times and was wondering if I can use Multipsk to decode the signal, I have tried but can't seem to get it to decode. Any information appreciated.

So, this is 18105.9 kHz? That would be in the 17 Meter Ham Band.

I've heard similar bubbly noises on the HF ham bands before, usually 30-50 kHz higher than the FT8 frequencies.

I'm also curious as to what the signals actually are. Some digital ham mode, obviously....
