Dead Link: All About Pactor and Pactor Modems – by Tim Hasson, W3IJP
Pactor, the protocol, traces it’s roots to the late 1980’s and efforts by a couple of German amateur radio operators to improve digital radio communications. Using the word “amateur” in connection with these guys is quite a piece of understatement. The present-day team includes a combination-degreed Physicist/Chemist who specializes in communications signal theory; an electronics engineer and programmer; and a military electronics designer whose particular specialty is something called “EMC”, or Electro-Magnetic-Compatibility. If that’s not enough, their business manager is a physician who used to specialize in nuclear medicine. Talk about your bunch of rocket scientists!

When these talented radio experimenters introduced the first version of Pactor (Pactor-I from here on, to avoid confusion later) to the rest of the world around 1990, it caused quite a sensation.
