Alas, no. Even if the original raw data was offered or retrieved the "index" was irrevocably lost. As I understand it this went well beyond simply scrambling the order and identity of the posts and extended to the inodes of the drive(s) it was contained on.
To the best of anyone's knowledge no one had or has come forward with a backup of the forums to date. Anything is possible but it appears even this possibility is vanishingly remote. Someone would have come forward by now.
We are fortunate to have a number of the former members of those forums here and may yet attract a few more. It is what we do here and how it reflects on what is fast becoming a shrinking niche interest that will attract those few remaining artisans and new blood.
Susan Nguyen, Gerhard Maurer , Mac (DigiMax) , our own Nomad Radio, and a select few others still cater to the relics of the citizens band past. Few others take it seriously enough to devote any time and energy to it. It's not like it once was 45 years ago (1977) when simultaneously CB radio expanded to 460KHz* and the first PLL radios appeared. Odd in the extreme that the MC145106, MC145109, SM5104, were created for purposes far removed from CB radio. That anyone thought to associate these phase locked loop devices with CB radio is curious. and who might have done it originally is mostly conjecture and myth.
You can trace the names of the original Cybernet group and Puerto Rico boards but who still remains a mystery.
I understand that many here are just getting into CB radio and I really don't want to discourage anyone for getting into any kind of radio.
But ...
Why restrict your interest to roughly a half megahertz of bandwidth? I for one choose to include this slice of radio spectrum in my interest but not limit myself to it.
So this all started with "bringing back the forum too?"
I'll ask you, what do you think you have here?
*
think about it , we have 40 channels, plus 5 "remote control" or "alpha" channels, plus 2x 1/2 channel width for above channel 40 and below channel one. 46 or .46MHz or 460KHz
