That is the communication of UNOWN. They communicate using Radio Waves, therefore, appearing on the radio.This is a secret, and is only found by messing with the radio in the ruins, somebody telling you (bot), and somebody telling you (person).
There are no Pokemon found within the Abyssal Ruins.
If you talk to the researchers, in the research centre outside of the ruins of alph They will tell you that it's the "Unown" pokémon making signals to eachother. Hope this helps. :3
There are two signals,one is in the lake of rage and Mahogany town. The other is in the ruins of alph.
The mysterious transmission in the ruins of alf are the UNOWN speakin to each other. Hope this helped.:)
When your inside the ruins you can get mysterious radio waves. unown can also communicate with each other using radio waves. wierd huh? i don't really know what they mean by that but why not give it a try?
The Cliffside Ruins are at the top of the cliff near the Mysterious Ruins.
