Bug-out Shelter #1 – The Signal
A signal appears every day... You must analyze it and decrypt it...

Mission
You watch your screen intently. On the usually silent frequencies, an anomaly repeats every evening at the same hour. A faint, steady breath, like a mechanical pulse lost in the electromagnetic fog surrounding the shelter.
Your first reflex is to check the internal systems: no failure, no parasitic noise. Yet the trace remains, persistent. You adjust the settings, refine the analysis spectrum, trying to isolate the patterns hidden behind this unusual flow.
Gradually, the structure becomes clearer. It is not natural noise, nor a random parasite: there is a logic, a repetitive pattern demanding to be decoded. Each sequence seems to contain coherent blocks, as if a message were concealed within.
The question is no longer whether this signal has meaning, but how to extract it without error, to reveal its true nature.
Rules
You have 2 messages at your disposal that you must decode.
You must return the decoding of these 2 messages, separated by an “_”.
