[amsat-bb] What is this phenomenon?

[Jean-Pierre Godet]

   Hi Hans, all,

   Between parts of non modulated carrierI receive a small piece of CW 
telemetry of XW-2E on 145.910 +-3 Doppler shift during the last pass 
over western Europe (BJ1SF is the callsign of XW-2E) :
BJ1SF DFH XW2
   then
BJ1SF DFH XW2 XW2 AAA

   As defunct XW-2E was deleted from the Celestrak data base used by 
GPredict, create a file named "40909.sat" in the 
~/.config/Gpredict/satdata directory with :

[Satellite]
VERSION=1.1
NAME=XW-2E
NICKNAME=XW-2E
TLE1=1 40909U 15049L   18196.46936794  .00000813  00000-0  44380-4 0  9999
TLE2=2 40909  97.4556 201.1699 0012256 291.4063  68.5862 15.17084954155908

(tle from Space-Track)

   Have fun withe Wiwang-2E, 73 !
