I think it's a spectrogram? or audio to image thing

ik this gonna sound dumb but does someone have a map of were they all are?

end of the waterfall stream in the cave behind a crystal, in the shack behind the starter house, 2 in sipping containers (one's in the one by farm upgrades the other in the cat/bomb shop) and IN the base of the town spire.

theres one just behing cave dwellers tent one in the upgrade shack aswell

Not Spectograms. I've seen this kind of thing done in Portal and Kerbal Space Program. The radios are emitting a SSTV signal that can be decoded into an image.

found another inside the main house first opening when you walk in the front on the right side next to the white couch

Cant tell whats's on the first one, but it all just seems to be shots from different places of the map

SO, would it be safe to say that exploring the related image locations revealed in the Spectrogram would contain some silly easter eggs?

There's a radio on the roof of the right side of the casino. It seems to decode into a photo of unity.

I checked some of the spots and didn't find anything out of the ordinary. My only guess is they are teasers for future locations

A lot of the radios seem to just lead to another radio, but yeah considering one of them is just a picture of unity its probably hinting at work on the map. Also there's another radio at the top of the waterfall outside behind some barrels. It has a picture overlooking the farm itself from up high.

can anyone figure out the one behind the breeding barn ive never used SSTV things before just learnt it, i'm thinking maybe the rendering or interference could be messing the image up.

one inside upgrade shack is a pic of an arrow pointing at the shipping container inside the underground toyshop where the other radio is located.

There's actually 2 images on the one behind the barn (or just one really long image I guess). But its still really hard to make anything out on it.
