Further thoughts

AO-29 is FO-29 my error

One other quick check is to point your antenna at the cold sky and read the
power out of the speaker and then point your antenna at the sun  the
difference should be ~ 4 db  see Google SETTI league for a spread sheet and
method to calculate receiver system performance Call if you would like to
chat
Thanks

We are having problems copying our sat also. To check out your ground
station you can  monitoring the AO-29 sat The beacon frequency is ~435.800
MHz  +/- Doppler ~ 100 mw and the noise when the antenna is pointed to cold
sky bandwidth of 15 KHz should be ~ -129 dbm I will monitor the sat and give
you my reading later today

Which all of us good luck


Thanks

Hello folks,
I am a little new at this so please have patience with ignorance.  Jin and I
launched two CubeSats a week or so ago.  The first is Trailblazer (mine) and
the second is DragonSat (Jins).  Trailblazer is from the Configurable Space
Research at the University of New Mexico (KE5VSH) and DragonSat is Drexel
University.   Our problem is that we haven’t heard from our satellites yet.
There could be a variety of different reasons.  First, the satellite didn’t
survive delivery.  Second, our antennas didn’t deploy or third, we have poor
ground stations.  As you can imagine, I am hoping for the third.  I can
pasting the TLE which is openly available on space-track and celestetrack in
this email.   It is very close (I believe) to our birds.   If you have a
chance, could you please keep your ears open in case you might hear us.
Please email any packets for Trailblazer to myself here
at craig.kief at cosmiac.org and for DragonSat to Jin Kang at kang at usna.edu.
 
Thanks again most sincerely,
Craig
 
 
Trailblazer 437.425MHz, AX.25, 9,600  (there is another satellite with the
same tx freq as mine there as well).
On my packets, if you see C0 00 A8 84
. You will provide me with a wonderful
gift.  I beacon every 50 seconds
 
DragonSat 145.870MHz, AX.25, 9,600. Beacons every 30 seconds.
 
Trailblazer Maybe
