   Hi my friends,

   I'm afraid I'm wrong, but it seems to me that the catalog number, 
therefore the tle of Zhuhai-1 1 (CAS-4A) and Zhuhai-1 2 (CAS-4B) are 
maybe inverted.
   Listening the CW beacon, the Doppler shift correction with fresh tle 
for Zhuhai-1 2 (CAS-4B) seems correct, but for his brother nr 1 
(CAS-4A), it looks like the bird is a bit ahead the prediction : at the 
beginning of the pass we have to decrease manually the frequency to 
chase the bird, at about the half of the pass it's the opposite, we have 
to hold a little bit the frequency shift correction.

   No ?

   Have a nice day all !
