Hello Devs.

I have a question about Signal Decoders.
I played too long on Ceto and gathered several signal decoders. Are they unique in number?
Do they unlock specific places only? Or do they spawn randomly and unlock coordinates randomly too?
Just to know if it is safe to sell the excess of decoders I have, since I unlocked a lot in that area.

Thanks for any info.

PS: I have some persistent coordinates for high-risk areas in the map. I already cleared them, but they keep in the map. When I return there, they are empty. Or at least, they seem empty.

Signal decoders are unlimited number, and will keep dropping now and then - but it's quite rare drop. I also don't see them in shops.

What's limited in number - is how many active high-risk areas you can spawn in any given system in the same time. The limit is 4 or 5, don't remember exactly.

Also, signal decoders come in all possible item rarities: white, green, blue, red. Red ones are very rare. And, grade of gear you get from activating a signal booster and then completing high-risk area it spawned - roughly corresponds to what color signal decoder itself was.

High-risk areas themselves are also color-coded accordingly. So, you have good chances to find some 1...3 superior items from a superior (red) high-rick area spawned by superior (red) signal decoder - but it's very unlikely you'd get even a single red item outta "white" signal decoder / high-risk area.

Signal decoders unlock high-risk areas only, one per decoder used. Decoder itself is consumed upon activation. High-risk area it spawns will appear in the system decoder name mentions, in some random place. It will be a mark on your map until you complete it. Each high-risk area will spawn at least one, and possibly even 2...3 (3 is rare) capital ships and about two dozens lesser ships.

Selling signal decoders is good cash when they are white, but blue and red ones are definitely worth to activate, instead. Green ones - depends on your crafting needs and piloting tastes. Me, early in the game i do some green ones, but once much played at max level - i sell green ones.
