[amsat-bb] beg my puddin'

2011-10-28 Thread K4FEG
pardon my caps lock on my post, I thought I was on the AO51 afternoon 
pass and I was yelling at the bird!

in reference to the lapsed call heard on AO-51:
Apparently several people heard/worked the station in question, the 
lapse could be an oversight or someone picked up this persons call. 
Based on what I heard the operator had been around the satellites 
previously. Maybe some one around him locally can ask him if he knows 
that the call has lapsed. The old FCC data base had him located in 
Alabama and he was giving out a grid locator of EL98, maybe he moved and 
lost track of his renewal date. We can give him the benefit of doubt 
until some one can ask if he knows that the license is shown as lapsed 
and recommend that he cease operation until he clears it up, altho' at 
the speed of government now-a-days that could be a while!


well I said previously that was my two cents worth I guess i'm up to a 
nickle now!

[amsat-bb] RAX-2 Launch In 30 Minutes

2011-10-28 Thread Bryan Herbert
They're in the final hold, weather is awesome and everything looks good 
to go for the 0948 UTC launch. Much like RAX-1, RAX-2 will have an 
Amateur Radio beacon spitting out 500mW of 9600 baud GMSK every 20 
seconds from it's right handed circularly polarized antenna... Such a 
spunky lil bird... Once she reaches orbit and the ground stations are 
able to track her they will upload the TLE data to their site.

Watched the launch from Las Vegas, NV.  It rose over the Spring Mountians
and arced southwestly and just before it disappeared behind the neighbors
rooftop, the first stage seperation occured.  At first, it looked like a
plane then I noticed the exhaust plume as it got bigger as it gained
altitude.

[amsat-bb] RAX-2 Decoding

2011-10-28 Thread Carl Rimmer W8KRF
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?

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!

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):

  Once Graham told me the noise was Orbcomm this morning, I added the TLEs for 
their satellites

  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

The email list increases exponentially;-)
I saw Jan's post with audio links. So just for completeness here's a file from 
the same spectrogram I posted yesterday, starting at around 09:33. The chuffs 
get quite loud and sometimes there's a double chuff, which I understand maybe 
from two Orbcomm sats.

Hi Roger et al

The spectrogram attached for the 1310z Prospero pass today shows a carrier 
between 13:16 and 13:20 that matches the Prospero doppler profile (pretty well 
vertical), and exactly on 137.560MHz.
There was some Orbcomm chuffing reasonably weak in the background, so it could 
be an Orbcomm satellite that exactly matched the doppler profile for Prospero.
I couldnt hear anything significant in the audio. This was received with a non 
directional antenna. Do you have a similar spectrogram received with a beam 
antenna. If the signal wasn't there then we may assume it was from Orbcomm or 
similar in a different beam direction.

cheers all

 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.

 We're hearing these 'chuff-chuff swooshes' too, though at times when our 
 software is not showing Orbcomm over our horizon.  Our TLEs may be slightly 
 out-of-date, though I think it would be a marginal thing.  Can it be 
 definitely confirmed that these noises are Orbcomm?

 Just the Orbcomm swooshes.

 Hi Tony,
 
 The chuff chuff noises are from space...they are a sort of beacon 
 carried
 on
 every Orbcomm satellite. They are 125msec long pulses of 57.6kb data and
 have a bandwidth of around 50kHz. They are quite distinctive when you 
 only
 hear one at a time but sometimes one can hear two or more signals at the
 same time and that sort of changes the sound:)

[amsat-bb] MCubed tracking

2011-10-28 Thread James Cutler
All,

Thanks for the tracking on RAX-2.  Everything is looking great.

Could you try tracking MCubed next?  We have been unable to hear so far.

Satellite: M-Cubed (1)
Downlink Freq: 437.485MHz
EIRP:  1W
Modulation Scheme: FSK
Protocol: AX.25
Baud Rate: 9600

M-Cubed
1 6U 011301.47661542 0.  0-0  0-0 0  0006
2 6 101.6483 233.3593 0252943 295.2624 199.6032 14.7900919707


Thanks for your help.

Jamie,

weak signals from AubiSat and M-Cubed, strong from RAX and E1P (good
decoding).
See spectrum here: http://www.dk3wn.info/p/?p=23521
