Cool little game. It took me a while to figure out how to do the frequencies correctly. There were a few that seemed to round down or up from the median value I found. As the other commenter said, I had no idea that the button allowed you to say yes or no. So I ended up getting the ending where you never hear signals again. I actually think I hit the button a couple extra times once trying to figure out how it worked. It's not clear what the aliens are saying either. So, you might want to work on being more clear on what the questions are that they're asking. Nice job nonetheless.
The frequencies have a forgiveness range so if it was say 10.500 you need to put it in between 10.400 and 10.600. It is overall meant to be vague what the aliens are saying as the goal is for players to hopefully want to explore more of the station for hints and by seeing other endings hopefully get a better idea what they are saying and discovering what 1 yes 2 no means is meant to be discovered as if you the player are discovering it in itself rather than the game straight up telling you. (Multiple button presses defaults to No) Thanks so much for playing!
