Looks like Valve updated Portal to include a radio on every level to reveal secrets of either Portal 2, or some other Valve game. Cool stuff!

"...these new radios each contain a hidden audio file that's transmitted when you carry them to one particular point in each of the game's levels."

Unfortunately I barely have time to play the games I WANT to play, much less replay this (awesome) game just to see cool secrets...
