The radio is on the wall with the hole in it. One way to reach this is to, while near the orange portal, shoot a blue portal at the ceiling just above the radio. Move it to where you collected the portal gun.

This chamber introduces you to the portal gun, and gives you the ability to create the blue end of portals — but not yet the ability to create both ends.

You can immediately see the entire chamber.

You start off with an overview of the chamber through a window. In the middle of the chamber is a portal gun, rotating and creating portals. Your first objective is to get the portal gun, and doing that requires waiting for the portal to be in the right place.

The stairwell where you will go through a portal.

Go down the stairs to the right, and wait until a portal appears, then go through it. This will take you to the ledge opposite where you first were, but you can't proceed to the chamberlock, as the door to it is closed. Walk off the ledge into the main area of the chamber, and pick up the portal gun.

Your first portal.

You'll notice that the orange end of the portal is permanently in place on the ledge you were just on, and you can use this to your advantage. Now that you have picked up the portal gun, the door to the chamberlock has opened, so fire the portal gun at any wall you can reach to create a portal between this level of the chamber and the ledge, then walk through the portal to get back onto the ledge. You can now proceed to the chamberlock.
