With repeated effort, your message goes through; you are picking a lot of static from Nav’s Rest beacon and assume it’s just the same with your broadcasts. The signal is improving as you get closer to your destination (it’s mostly unnoticeable, but since K10 is a droid, they notice a dBm increase).
The transmission you receive
is accompanied by this sound, which you’ve reconstructed from your captures.
