Patrick, your emory is a little hazy regarding the history of this publication.
As an AMSAT area coordinator, and with AMSAT-NA's blessings, I released the AMSAT-approved "Work AO-51" tutorial on September 3, 2007, to the world.
That grew to "Work Satellites With Your HT" tutorial I produced in January, 2008 - again with AMSAT-NA's blessings.
Then other variants began to appear ...
BUT THE BOTTOM LINE - in my mind - is getting the information out. And as accurately and timely as possible. Over the years, my tutorial has been revised / amended / improved more than 20 times - to keep up with changes and new info.
No problem ... ancient history, actually, in the scheme of things. Many thousands of my tutorials have been downloaded and handed to convention attendees and club members, and I hope the AMSAT-NA download page gets promoted with updated and current info for all, too.
