[amsat-bb] Pratham: IITB Student Satellite Beacon Active

[Jean-Pierre Godet]

   Jan, your reception is better than mine ! Thank you for the link to

   By the way looks like, comparing with september records, that the 
signal level is lower. No ? I agree, my equipment is not too good.

   A piece of the record of this morning pass is here :
http://f5yg.pagesperso-orange.fr/incoming/PRATHAM_orb1216_18dec2016

   With a vertical half-wave antenna (physically 1/2 wave, electrically 
3/4 wave) over a large ground plane hidden in the attic, the AMSAT-UK 
FCD-Pro+, Gqrx as SDR prgm, GPredict for the Doppler tracking.

   Have a nice Sunday, 73 !
