60th Anniversary of OSCAR 1

December 12th was the 60th anniversary of the launch of OSCAR 1, the world’s first private spacecraft.

An article entitled “How Amateur Radio Fanatics Launched The World’s First Private Communications Satellite” appeared in Inverse. This article is largely based on an interview with Lance Ginner, K6GSJ, one of the designers of OSCAR 1 and can be found at

A video of Lance Ginner’s 2011 AMSAT Symposium Keynote describing the early days of Project OSCAR is available at

Ginner also took part in the Foundations of AMSAT panel at the 50th Anniversary AMSAT Space Symposium in 2019. Video of this panel is available at

Upcoming Satellite Operations

W8MTB: On Wednesday December 29, I will be in EN71. If you need EN71 please email me and let me know so I can listen for you. No passes are a 100% guarantee but, most likely I’ll be on AO-91 and maybe SO-50.

Radio Operadores del Este Club (KP3RE) and its FB Ham Satelites Puerto Rico page will be giving away until December 31, 2021 all the stations that have contacted Puerto Rico’s 4 grids FK67, FK68, FK77 and FK78 on Sat Mode. Need LOTW evidence (Photos) request via [email protected]

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

Clint Bradford, K6LCS, now has presentations lined up to start the new year, including three clubs in Canada, and clubs in Florida, California, New York and Nevada!

Think a 90-minute lively, informative, and fun “How to Work the Easy Satellites” Zoom presentation would be appropriate for your convention or club? Always included are overviews of the ARRL, AMSAT, and ARISS. And pre-presentation questions are solicited and welcome.

Send an email or call!
