Kind of blows my mind how primitive this whole system still is. Audio quality is really bad. They're sending instructions by voice. The way they know who is speaking is by just saying their callsign with every message. There's got to be a better solution surely?
I think that the audio we are listening too is from some ground recording station that isn't necessarily near the airport. We aren't listening to a recording of what the pilots heard or what air traffic control hears.
This is one of the highest quality recordings of such traffic that I have heard. They are usually a lot worse.
