The cogwave jammer is an item which is added to Fallout 3 in the Point Lookout add-on.
This is given to you by Desmond in the quest Thought Control to block Professor Calvert's signal.
- The item itself does not have a world object form.
- It is classed as a quest item and as such cannot be dropped once picked up.
PC If you choose to crush it in the trash compactor, you can still place it on the top of the Ferris Wheel afterward. [verified]
