Transmission Received (Radios 16-17/26)5 hints left
Ten radios remain, and for the first time ever, a chamber has TWO radios to find!
The first one is on top of the piston in the starting room.
How do I grab it?
Shoot a portal onto the wall next to the piston, then peek through another portal to grab the radio and bring it down to the ground.
Where do I take it?
The light will turn green the radio's practically touching the starting elevator.
Where is the second radio?
This one goes hand-in-hand with one of the game's more well-known 'softlock spots'; it's next to the activation hole in the final room of the chamber.
How do I grab it?
Press both standing buttons in rapid succession, then place a portal at the bottom of the 'tower' that holds the activation hole.
Shoot another portal on the ground near you, jump down into it, and move forward into the tower - just don't forget to grab the radio before you're kicked out.
Where do I take it?
The light will turn green when the radio is next to the exit elevator.
