The Amplified Radio Device — Oxenfree Walkthrough

Oxenfree walkthrough: acquire the Amplified Radio Device from the Sunken Submarine to tune into new frequencies and progress through the game's later stages.

Later in the game, you will acquire the Amplified Radio Device from the Sunken Submarine. This is not a separate item you equip, but rather an upgrade to Alex's existing portable radio. Once obtained, Alex's radio gains enhanced capabilities, allowing her to tune into more powerful and previously inaccessible frequencies. This upgrade is crucial for the latter half of the game, particularly for interacting with the Lighthouse and confronting the entities directly.

Impact: The amplified radio allows you to disrupt stronger supernatural phenomena, open more complex gates, and access frequencies that reveal deeper secrets about the island's history and the entities' true nature. It's a narrative progression item that signifies Alex's growing understanding and power over the supernatural forces at play. You don't need to do anything special to 'use' it; Alex's radio simply becomes more powerful automatically after this point.
