HackPittsburgh member Derrick Brashear and guest speaker Alex Lang will explain communication signals, how they’ve developed over time, and how things look in person on the tracks.

They’ll also explain how the radio system works, walk through some free software that you can use to decode the signals, show off the hardware used to pick them up, and even give a live demo!

As with all HackPittsburgh Friday events, this talk is open to the public!  HackPittsburgh is located at 1936 5th Ave. in Pittsburgh, the entrance is by the garage around back on Watson St.  Doors open at 6pm, and the talk should begin around 7pm.  Hope to see you there!
