Within Sector10, you need to collect items to spawn the bosses of the zone. It works similarly to the Pocketboss mechanic in the Shadowlands. You need to gather parts from the regular aliens in the zone, tradeskill them together and spawn them at certain points inside the zone.
So, what items do you need to gather to get this party started?
Right clicking the Tuning Unit - Inactive turns the item into a Tuning Unit but BEWARE it turns the item NODROP. The X Signal Relay also becomes NODROP. So be sure to do so on a character that can enter Sector 10.
Note: The Tuning Unit does NOT get used up in the process, which means all you need to gather to make another Signal Relay of that particular "Unit" is 4 Fuel Glands, 4 Broken and Powerless Signal Amplifiers and 1 Inert Kyr'Ozch Teleportation Relay.
Tuner (former generals):
Rho: East General
Sigma: North General
Kappa: West general
Alpha: Middle General
Congratulations! Now head into Sector 10 to pop out your "Alien Pocket Boss".
Best of luck!
