Mark Durenberger, a veteran technologist and a friend to Radio World from its earliest days, has produced an essay documenting AT&T’s contributions to radio. He’d like to share his document with you and get your thoughts about the subject.

Durenberger writes in his introduction: “About three years ago, inspired by a piece by James O’Neal in Radio World newsmagazine, I came to realize that, while many of us grew up in a broadcast industry created in part by AT&T, there’s no easily accessible access to the full detail of AT&T’s contributions.

“Furthermore, those with first-hand experience in an earlier analog world were retiring and the heritage of experience with AT&T methodology was being lost. This might be a way to secure factual and anecdotal input from those who were part of that picture.”

His eBook is free of charge to anyone requesting it.

Topics include the founding of AT&T; the introduction of “Long Lines;” the development of wireless; AT&T’s broadcasting “experiment”; the evolution of national broadcasting networks; alternative methods of getting programming from station to station; the evolution of the VU meter and true “high-fidelity” audio transmission through the use of “carrier.”

Call it a work in progress or an eBook looking for its next chapter. Durenberger will email the PDF to anyone who asks; just drop him a note. In return he requests only that you share your thoughts and reactions so he can continue to update the story.
