Bring all radio frequencies to Gina.
This is in a side quest in Gizeh which you can start by talking to Gina in Nawal's tent. There are four frequencies to collect.
This is an Objective, rather than All-the-things, as the quest gives you a map with four areas, so its basically an Objective to complete the quest rather than collectible-like.
