Poseidon radar transmitter

Poseidon radar transmitter is a miscellaneous item in Fallout 4.

Gameplay
The Poseidon radar transmitter is a radar component that the Sole Survivor needs to retrieve in order to repair the ship's guidance radar during Last Voyage of the U.S.S. Constitution.

Locations
There are two available locations Mr. Navigator might send the player character to recover the radar transmitter:

 * Poseidon reservoir

Related quest

 * Last Voyage of the U.S.S. Constitution

Bugs
This item can become stuck in the player's inventory, if it was already acquired and if the player chooses to fix the guidance radar via jury-rigging. This can occur even if the item is obtained after the quest has already been completed.
 * It can be removed from the inventory by using the console command.
