I have recorded the following from Explorer-1 [PRIME] I couldn?t decode
the data and when I listen to it, I hope I am doing something wrong
because it doesn?t sound right.
Audio recording of E1P-U2 at 28-10-2011 12:40 UTC:

Interesting since I am in Melbourne, Florida and my grid is EL98. If
they are giving that grid out they can't be in Alabama would be my
presumption.

The HB9AFO website is saying that the SwissCube project management is to
cease operations.
They seek two radio amateurs who are equipped to receive and send to
SwissCube to maintain contact with the satellite until the end of its life.
These operators will be trained for this purpose and will benefit from the
support of the Space Center EPFL. Contact mvonlanthen@xxx.xx

Message-ID: <4EAAC34F.1050107@xxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I have installed the RAX-2 decoding software hoping to be able to copy
and decode the telemetry. I am using a TS-2000 with a SignaLink USB and
AGWPE as the TNC. I am not able to get the software to recognize this
set up. I have AGWPE setup in Kiss Simple mode at 9600 Baud. (I use
the SignaLink with the ARISSATTLM software and it works fine.) Can
anyone tell me if this setup will work with the RAX-2 software? If so,
what am I not doing or doing wrong?
Thanks and 73,

Hi Carl, I have not used AGWPE before as a TNC. How does it output it's
data? A virtual serial port?

OK - so that's definitely Orbcomm (from the spectrogram). Have you got
audio of this?
We hear a chuffing sound intermittently (ie., it comes and goes in
interval of minutes), which happens when neither Orbcomm nor Prospero is
reported by our software to be above the horizon (is this the pager
stuff you're talking about?). We also heard another thing a couple of
days ago, though we're still not 100% on what that might have been (it
appeared to be fading as Prospero receded to the North - though was it
an aeroplane on 137.56?).
Someone yesterday has supposedly heard something that's wasn't Orbcomm
during the early evening pass. We'll look into it.
The pass we're going to try today (for the sake of ceremony, really) is
(again, times in BST = UT + 1):

Hi Roger,
All understood..I have put the currently 28? active Orbcomms into Nova here
and almost all of the time there is at least one above my horizon and I can
hear the chuffing noises..will be listening again this evening
Do you have details of the on board power system? For instance what are the
batteries? If the batteries have failed short circuit will they be clamping
the bus to 0volts? Can the power system work with open circuit cells? What
is/was the default power up operating mode?
good luck!
Graham

OK - so that's definitely Orbcomm (from the spectrogram). Have you got
audio of this?
We hear a chuffing sound intermittently (ie., it comes and goes in interval
of minutes), which happens when neither Orbcomm nor Prospero is reported by
our software to be above the horizon (is this the pager stuff you're talking
about?). We also heard another thing a couple of days ago, though we're
still not 100% on what that might have been (it appeared to be fading as
Prospero receded to the North - though was it an aeroplane on 137.56?).
Someone yesterday has supposedly heard something that's wasn't Orbcomm
during the early evening pass. We'll look into it.
The pass we're going to try today (for the sake of ceremony, really) is
(again, times in BST = UT + 1):

Hi Roger
Once Graham told me the noise was Orbcomm this morning, I added the TLEs
for their satellites
(http://www.orbcomm.com/Collateral/Documents/English-US/o11292.tle)
to my SDR Radio software satellite definitions. Here's a pass I recorded
from one of them this morning, and you can see that the "chuff-chuff" on the
left hand side has structure which is kept vertical by the doppler
correction. The other crap and pager cross talk etc bends with the doppler
correction. I think that proves the point.

Hi Roger
Nothing other than the chuff- chuff on the 1600 pass. And as you said, its
also there with Prospero over the horizon. I 'm not using a beam presently
-
using a 360deg parasitic Lindenblad for circular polarisation, but it is
susceptible to all the high power pager stuff nearby. Its just strange
that
there are elements shifting in frequency in the chuff chuff like a signal
from a real satellite.
