Apologies for my late answer, but no, that's incorrect. For the longest time, as stated in this very page (and I know this from experience too), Unknown Signal would become unaccessible once you watched it for the first time. The door leading to the inside of the building where the ECHO is would remain closed, with no button prompt to open it or anything. Perhaps it was a glitch (which it could very well be) or it was intentional, but the point is that you couldn't enter the building, thus you couldn't get to the ECHO. However, at an unknown point before The Division 2's release, I found that this very same door was open wide, allowing me to access the ECHO for the first time in years.

Judging by what you say, it's probable that my inability to access Unknown Signal after completing it once might have been due to a glitch.
