Interest in planned satellites carrying 10 and 15 meter transponders is growing steadily, owing in large part to the DX possibilities these satellites will open.
The best source I know of for information about propagation from such satellites is the Space Radio Handbook, by the late John Branigan, GM4IHJ (SK), published by RSGB. Unfortunately, this book is out of print and may be difficult to find.
November QST arrived several days ago. As always, I turned to the monthly column describing the contents of QST 25, 50 and 75 years ago. Was I surprised! In the "50 Years Ago" section, about November 1968 QST, was an article I had written, about which I had totally forgotten in the intervening 50 years.
It was called "Antipodal Reception of Satellite Signals," discussing what was then known about such things and proposing an experiment to be carried out using the 10 meter beacon to be carried on OSCAR-Australis, the name of which was changed to Australis-OSCAR 5 after its launch in 1970.
Readers of that article will also want to read the results of the AO-5 propagation experiments, which I presented in October 1970 QST. You will find these articles in the QST archive on ARRL's Web site, under my call sign at the time, K2QBW. Unfortunately, copyright laws prevent my attaching them here.
I turned out to be in very good company. Also researching in this field at the time were Dr. Owen Garriott. W5LFL, later to be the first US ham in space, and Dr. O. G. (Mike) Villard, Jr., W6QYT (SK), an early pioneer of SSB. Both were then at Stanford University.
