Turn to the left and fire the other portal on the floor there and drop down. Shoot a portal on the platform further away.Go through the open door behind you and walk to the other end of the corridor and drop down.Drop down on one of the platforms and fire a portal on the floor.

Place the cube on the button and fire a portal on the wall with the open door.Pick up the cube and walk over to the first part of the chamber. Push the switch and go through the portal.Jump behind the switch again and put a portal on the wall.Place the cube in front of the glass and place a portal above the glass.Pick up the cube and wait for the Unstationary Scaffold to get near you.Shoot the other portal on the floor below and drop down through the portal.When the panels are in the correct angle, put a portal on the panels and then turn left and go to the ledge. Shoot a portal above the glass on the other side and the other one on the wall next to you.Get on the platform and wait for it to stop at the other end.Wait for the Pellet to reach the catcher and walk to the Unstationary Scaffold.Enter through the portal and press the switch. Quickly fire a portal on the wallpanels facing the switch and the other one on the wall near you.Shoot a portal on the wall where the emitter is about to fire the next Pellet and wait for the Pellet to go through the portal.Go stand next to the switch and fire a portal on the extended walls on the other side of the chamber. You should have deactivated all of the four turrets.Put a portal there and the other one where the emitter is going to shoot next. At the back of the chamber there are extended walls facing the last turret.Do the same again for the turret aiming at the same wall and to the turret near you.Wait for the Pellet to knock the turret over. Shoot a portal on the wall where the beam ends and the other one where the High Energy Pellet emitter is going to shoot next. Follow the aiming beam of the turret on the platform near you.Crouch and get to the second part of the chamber. Shoot the other one on a platform below and jump through it. Place a portal on the extended wallpanels near the ceiling.Fire a portal on the same wall and put the other one near yourself and go through. Shoot a portal on the ceiling above it and the other one under yourself. Put the other portal on the wall above the goo and jump through it. Turn right and place a portal on the ceiling.You should automatically drop through for the second time and then land on the other side of the Goo.Go back in the hall and the shoot a portal on the floor at the end of the hallway.Turn around and fire a portal on the third panel above the hallway. Whichever method you use, proceed to bring it to the exit. Throw a cube at the opening, knocking the radio into the section with the button.Place a portal on the closest wall, and grab the radio as you make a running jump by it.Note that this is also a method of getting the cube to the button without bringing it through with a portal. Now jump through the portal while pushing the cube into the opening to knock the radio through.

You should be able to move the cube partway into the opening.

While holding a cube, move as far as you can into the orange portal without falling.You may be able to land in the opening itself, then be able to grab the radio (if you didn’t already knock it down) and continue. Jump through while looking towards the opening and holding forward.Grab the radio as you fall through (note that it is possible to fall with you on one side of the grid and holding the radio on the other side, so be sure to walk in the correct direction to not let the radio run into the grid).Place a portal on the ceiling next to the opening.Hop onto the cube, and then when you jump, you may be able to grab the radio if you are in the right spot (you must be able to at least see the antenna). Place a cube just before the boundary.Retrieving the radio is difficult, especially with the danger of it hitting the grid and disappearing (remember to save, as the radio will NOT reappear!). The radio is within the small opening between the two sections.
