Want to identify this 11387

11387
2020 UTC
Bursts
USB
Central Florida, Orlando, USA
Was searching the HF Aero Band for voice activity when I came across this sporadic sound.
I parked the SDR's in this frequency and was listening to the sound, came in bursts lasting about three seconds each and about 10 seconds apart.

Sounded to me like some sort of data bursts, of what, I have no idea being as the frequency is in HF. No voice transmissions heard anywhere near the frequency.
I also have a sound file. Can't find here an option to do that.

Without a sound file it is not possible to confirm, but this is almost certainly HFDL, High Frequency Data Link.  This is a known frequency for HFDL and the image looks like it is probably HFDL.  A more detailed closeup image of the signal on the waterfall could help a little also.

HFDL is HF based ACARS, it is a data link used in aviation, including aircraft in flgiht.
