This is the first time that it has been reported openly on this frequency but, like NOAA 11, it has probably remained unreported due to the limited number of observers checking the SGLS Frequencies.


The plot shows a good Doppler curve with the signal exhibiting data sidebands. The sudden disappearance is due to it being switched off.


The transmission is probably carrying data from the onboard TIPS instrument.
