Signals from Space ( for the spacecraft and outer space monitoring enthusiast )
Welcome to the interesting world of spacecraft monitoring. This webpage includes a collection of a series of active orbiting satellites that most anyone could receive using a modest scanner or multi-mode receiver. Some of the higher L-band and higher frequency spacecraft may need a larger dish antenna but this webpage will focus mostly on satellites that could be monitored with a modest scanner or multi-mode receiver and a omni directional or small beam antenna .
To track and listen to the satellites, the satellite KEP files of the satellite descriptions below will have to be updated and loaded in the satellite tracking software. Tune the receiver to the below frequencies , wait until the satellite is within range by using the satellite tracking software and begin listening. The best reception will most likely occur when the satellite is above 10 degrees elevation.
