I set the software-defined radio so that one screen would display a whole night’s worth of data on 2242.5 MHz. Strange shapes showed up!
The first two below display a strange change in Doppler rate just after AOS, which seems to be after closest approach! The third one looks “normal”
Picked up the strong signals easily on 2 November 2007 at 1627 UT.
Picked up on 2250.0 MHz at 1027 UT 3 Nov 2007.
Picked up on 2235.0 MHz at 0956 UT on 5 November 2007
