[amsat-bb] AO-40 Reception

[Jesse Morris <w4mvb@xxxxxxxx>]

Hi To All,

I got my first reception of AO-40 before perigee this morning (Sunday). 
Signals were weaker than I had hoped but the squint angle indicated by IT
was pretty high so I'm still encouraged.

Set up is a Drake converter with all G0MRF mods, 123 mhz to 29 mhz IF
converter into a FT-840 and a 21 turn helix.  First detected signal at
1535Z - MA 246/Squint 108.  Signal was very weak and I could only hear it
on the peaks of the QSB.  At 1550Z - MA249/squint 89 the signal was solid
copy but still weak (4 to 6 db above the noise on peaks).  Signal peaked
at 1600Z about 10 db above the noise level just prior to LOS -
MA251/squint 67.  LOS at 1601Z.  I did not decode any TLM.  The signal
was strong enough for the last 10 or 15 minutes but I couldn't cope with
the doppler and QSB.
