Regarding Observation 249962
This is a recording of the first Danish satellite, Ørsted. A clear signal can be seen on the waterfall, but if you listen to the audio, a clear voice can be heard on top of the tone. It sounds like an AM broadcast station being demodulated with an SSB receiver, so you can’t make out what they say, and one minute before the end of the recording, you can hear music.
How is this possible on 2296 MHz? Also, the strength of the voice follows the strength of the signal.
The reason I started looking for this satellite is that there is talk in Denmark now about start listening to it again.
