The Dark Phantom Strikes! was a live, episodic radio mystery and supernatural-detective drama broadcast by WXXL Radio in 1926, just days into the station going on the air. Gregor was sound engineer on the show.

The program starred the Dark Phantom, a pulp vigilante armed with his "Tibetan Darkness Power" which could render him invisible, along with his sidekick Buddy, facing off against the machinations of Dark's Phantom's arch nemesis: criminal mastermind, Marco Phillips.
