ARRL

Space Communication

Introduction

 

On December 12, 1961, Amateur Radio entered the Space Age when OSCAR-1 was launched. Since then, amateurs from more than 22 different countries have launched over 70 satellites, exploring both digital and analog satellite technology. Many of the latest birds have been school experiments, training scientists and engineers. But, you don’t need to be a rocket scientist to participate-- Some satellites operate FM and can actually be worked using a dual-band handheld transceiver. An excellent place to start is the AMSAT-NA FAQ page. AMSAT, or the Radio Amateur Satellite Corporation, has played a key role in building, launching, and using amateur satellites.Occasionally, Radio Amateurs can talk with the astronauts on the International Space Station. For more information check out ARISS.

  • An Amateur Satellite Primer
    QST April 2000, pp. 36-41
    If you think you might like to work satellites but think it is difficult and expensive, this is a must read
    (Note: This article contains a chart showing the Uplink and Downlink frequencies of several amateur satellites at the time of publication of the April 2000 QST. These frequency pairs can be reversed without notice by the control operator of the individual satellite. If you don't hear the signal near the Downlink frequency, you might want to check for the latest status.
