NOAA-9
NOAA-9, also known as NOAA-F, was an American weather satellite operated by the National Oceanic and Atmospheric Administration. It was part of a series of satellites called Advanced TIROS-N, being the second of the series. NOAA-9 was launched on an Atlas E rocket on December 12, 1984 from Vandenberg Air Force Base, California, United States.
The last contact occurred on February 13, 1998. In late 1999 a transmitter on 137.5 MHz started working again, sending an unmodulated carrier. It seems to transmit while the satellite is in sunlight.Specifications
