While I was casually skimming the bands for anything especially noticeable, I stumbled upon this flight traffic. When aircraft get too far away for the use of VHF on their route to their destination, they can switch to HF. This is flight info and status of 1 or 2 flights. Just another reason why HF is still needed these days! The broadcasts you see directly down from the voice traffic was actually %100 digital. It is actually fully automated software that talks to other aircraft and shares information.
