Fellow Satellite Trackers,
We at Cal Poly have seen some unpredictable behavior on our satellite, CP4. Since we only have contact with the satellite once every 12 hours, it would be extremely helpful if we could get some global support with collecting beacons to get a more complete picture of the the satellite's health. For those who are interested, please send any collected data (audio or decoded binary) to my email address,

Below is the information needed to track our satellite. Thanks everyone for your help!
