   Hello my friends from AMSAT-Argentina !

   Your bird was heard here in the North of France, very very strong 
signal, the sort you received with dash and dots, strong especially 
according to the conditions : ground plane antenna in the attic, AM 
receiver and 456,9 kHz transmitter poorly hacked together to receive CW, 
GaAsFET preamp.

   Orbit nr 22133, acquisition at 1202 UTC, lost at 1215 UTC (elev. then 
was about 4 deg.). The max elevations was around 42 deg.

   I recorded audio and spectrogram, I send you both later.

   Best 73 !
