Fundamentally, you're coming at this game the wrong way. It's not a signal searching simulator like (most) of Signal Sim. It's primarily a horror game with lots of silly elements, where the signal searching is more of a vehicle to take you to some of those events.
That's why you have to make a trek to the dishes to get the hash codes every day. It's the game attempting to put you in a situation where something happens, or at the very least putting you in a situation where you're uncomfortable because you're outside the "safety" of the base. It's why the base is so dirty; it makes you feel like something went wrong. It's why the game doesn't support multiplayer, despite being made on Unreal Engine; to give you the sense of seclusion and solitary confinement in the forest. All of it works together to try and make you feel alone and scared.
TL;DR
This isn't a SETI-Sim. It's a (silly) horror game.
Also, I hope the socially-stunted kids shitting on you doesn't turn you off from the game. Being a free horror game, it's kind of attracted a lot of the...shall we say, FNaF kids. Not helped by the fact that the game is comedic and has plenty of memes in it.
