Borderlands 3 has 22 Crimson Radio Locations. The Crimson Radios are a type of collectible that count towards completing all Crew Challenges. They are optional and don’t unlock any trophies or achievements but you get 10 Eridium, some money and XP for each one.
None of the Crimson Radios are missable! You can still find all of them after the story in free-roam. They will be marked on the map with a green icon when you go near them. The ones you found will switch to a blue icon, which makes it easy to see what you’re missing. You can also keep track by pressing L3 / Left Stick on the world map and D-Pad Right to open the Challenges tab.
Place waypoints on your map where the screenshots below show the location. When you get near you can place a waypoint directly on the Crimson Radio to make it easier to find. All of them are in high places that require some climbing. The guide below shows all climbing paths marked with red arrows. Everything is ordered by planet. If you haven’t been to a region yet, you must advance the story further (e.g. most Pandora regions are only accessible after second visit to Pandora later in the story).

‘They are optional and don’t unlock any trophies or achievements’, best news I got today. Some of the jumps you have to do are really annoying. Thanks for the info and for all your guides in general.
