Not sure which exact contest ...
I haven't kept up on them ... But go to AMSAT-NA's Web site ... I believe AMSAT-UK is having "too much fun," too, and might be running a "contest" of sorts.

P.S. - Both of these AMSAT groups deserve support ... both are at the forefront of this aspect of amateur radio, and have great resources for us all.

P.P.S. - Sorry 'bout that. People here ALREADY know that AMSAT and AMSAT-UK deserve our support. Preachin' to the choir ... sorry ...

Not sure which exact contest
 
Clint, I am not sure either Hi Hi on AMSATs web site it says" * Those who do hear the secret word or call sign please do not put it out to the world. That would ruin the contest for those still waiting for their station to be in range." So i am wondering what contest they are talking about
 
thanks,

how long is ARISSsat-1 going to be up?
3-6 months ... maybe longer!

... are you then entered in the contest? It there only one secret word are are there several?
Not sure which exact contest - but to receive a certificate, just one Secret Word report is necessary (follow THEIR rules for submitting reports!) And there's a secret word for each voice recording, I believe ...

Hi,
 
how long is ARISSsat-1 going to be up? by that I mean once they deployed it as I understand from that point it began falling to earth. SO how long are they guessing before she  either quits working or burns up on reentery. Also once you hear the secret word and send the report in are you then entered in the contest? It there only one secret word are are there several?

... mag mounts on cars ...
One thing the instruction manuals for mag mounts don;t tell you: They are guaranteed to scratch your car's paint finish. GUARANTEED. No matter how well you wax the surface and keep things clean, you'll have a ring o' scratch there in a little while.

I have a mag mount. But I use it when using a rental car ... or when, on trips, I'll hang it from a hotel's curtain rod or window frame ... They HAVE their purposes!

That would be great!  The NMO Mount, is the standard, "drill a hole in the roof of your car" type of antenna mount.  They're reasonable inexpensive and easy to work with.  I'm not sure what material your dish is made of. 
 
I assumed they were fiberglass or something non-matelic, so I did not thing of the mag mount.  In any case, it would be good for testing.
 
The mag mounts work by making a "capacitance" connection to the vehicle body to work as the ground plane.  If your test works reasonably well with the mag mount, it should work even better with a direct connection, like an NMO mount or something like that.
 
Let me know!

Jimmy,

A friend of mine who is also a Ham is pretty good with antenna design.  About a year or so ago, he and I were kicking around an idea that is similar to the track you're on.

His idea was to take the dish from a Direct-TV or Dish Television system, remove the center element, and replace it with something like a Larsen 2/70 Quarter Wave, NMO Mount antenna.  This would be sticking straight out from the center of the dish.  This would be on the "Round Dish" not the "Oval Dish."

His theory was if the tip of the antenna would be aimed at the satellite, the dish would reflect the signal against the otherwise vertical antenna and visa versa.  Since the Larsen 2/70 is already tuned as a Dual Band Antenna, no diplexer would be needed.

Remember, this was only a theory, and has not been tested, but if you already have the dish, the only thing you need is the antenna and the mount.  Let me know if you try it and it works!

Thanks Clint,
 
Yep now that I know MMSSTV is working on recieve I can work on reciecing packet from ISS and a transmit interface. I think I say somthing about a probram like MMSSTV that decords packet I have to look.  I will Work the FM birds two way soon. Hamfest coming up on Sat never know what I will find.

Re: ARISSAT-1 Heard it :)

Siegfried Jackstien
 

How did you record the passes
With software defined radio? Hdsdr??
Or with a conventional recorder the fm downlink??
Arissat has a telemetry and cw beacon on 145919 (for decode you have to tune
500 hz lower in usb) and a fm transmitter on 145950
And the output of its linear transponder (uhf up 2m down) in between those
(922-938)
On 950 there are these signals interchanged >>> sstv pics stored, sstv pics
from one of the cameras, spoken telemetry (computer voice), spoken greetings
in many languages (spoken from kids and stored on the sat) ...
For receiving the sstv pics you have just to use ANY sstv programm
Mmsstv or others will work
For decoding the telemetry you have to use the arissat tlm software
http://www.arissattlm.org/

further info about reception, reception challenge, "the secret words
challenge" etc can be found here:
http://www.uk.amsat.org/2011/08/04/arissat-1-reception-challenge-2/
and here:
http://www.amsatsa.org.za/ARISSat-1.htm

if you recorded the pass with an sdr (hdsdr or similar) you can play it
back, decode the telemetry, play it again and listen to voice (or receive a
picture) ....
hope I could help a bit :-)

Re: ARISSat-1 BPSK-1000

Siegfried Jackstien
 

Does pcsat32 has a dde link??? If yes then there is no need to switch over
to orbitron .... what sat soft makes the tracking and doppler shift is not
important ... the importand thing is to shift the tune in hdsdr and not to
shift the lo (as fcd unlocks for a millisecond when you set new lo)
I let hdsdr stay on lo 145940 and record the whole rf ...
After decoding the bpsk "live" I played the recording back and decoded sstv
/voice .... so you can do both with one pc ...

Thanks for the info I'll download Orbitron and give it a try.
Not looking forward to the learning curve, I just got SatPC32 working
correctly, and just figured out the ARISSatTLM package.
SatPC32 handles the doppler and tracking well, I just don't get a good
signal from the CW Beacon and the SSB Telemetry. My understanding is to
tune around 145.919MHZ USB until the CW ID tone is around 500HZ then every
thing should lock and work. I've got a 65 deg. pass coming up at 10PM,
I'll try again. Because this bird isn't spin stabilized, I think the deep
fading is doing me in.

Yes ... me :-)
I used orbitron for tracking the qrg
In hdsdr I switched the dde driver to control TUNE not the LO !!!
The fcd makes coarse steps when you tune it
The sdr soft can do finer steps and with that you can be right on spot
Ok here the setup
Orbitron for tracking qrg (any tracking soft with dde link should work)
Qrg is sent to hdsdr
Hdsdr sets the lo for the fcd 10kc lower as the qrg that orbitron sent
via
dde (so during a pass lo is NOT changed!!) if the qrg is not in the
passband
I change it after starting to be on 145940
Hdsdr does not change it anymore so pll of fcd stays locked!
In orbitron I made a new textfile : 37772.txt
Content:
**********start of txt file******
NAME: RADIOSKAF-B (ARISSAT-1)
LAUNCHED: 2011/08/03@18:43:00 UTC

Notes: ARISSAT-1 was launched without uplink antenna!
*********end of file************
(delete the lines with the stars!!)

You maybe have a bit different qrg to put in the file
So maybe you have to change tha value a bit

the goal is that you have the cw note at 500 to 650 hz
(about 550 worked best for me)

Now I routed the audio from sdr software to tlm software via virtual
audio
cable ....
The tlm software locks on the cw note ... so if you have it tuned right
on
spot you should also receive the data
Hope that helps

Anyone have any luck receiving the telemetry? I've had success with
the FM
voice and SSTV but not with the telemetry. I have briefly heard the CW
beacon but not long enough to get tuned in to receive the data.I'm
using
the ARISatTLM software, yagi antenna Az/El rotor, tracking with

using doppler correction, etc..

To decode recorded files (wave files)
Set record in in windows mixer to "what you hear" "speaker out" "sum" "lineout" ...
Play the wave file with a waveplayer (any will do)
Start mmsstv decoding
Now mmsstv uses the speaker out of the mixer as its input
Should work

Hi Forrest,

I'm not sure if you recorded the SSTV audio directly on to your computer
from the radio or made a recording on a digital recorder to then transfer
to the computer. I downloaded MMSSTV and although there are files you can
use to test it, it wasn't clear (to me!) how to get the software to read
the test audio files on your computer.

When ARISSat was being tested from the ISS, I recorded the SSTV audio
during a pass using a small digital recorder with a cable( with 3.5mm jack
on each end) connecting the radio to the microphone socket on the
recorder. After the pass I went back inside and started up MMSSTV and then
just plugged one end of same cable into the earpiece socket on the
recorder and the other into the microphone socket on my computer. I didn't
adjust any input levels. I pushed play on the recorder and MMSSTV started
decoding and displaying the image immediately.

It seems like the software is either set for a mic or line input as a
default and it definitely would be nice to how to switch it so that you
can decode audio files on your computer.

Cheers

It's things like this that keep me excited about Amateur Radio! I copied
the FM downlink on the Aug 9 0543Z pass last night in Torrance, Calif.
Used a VX7 with a ¼ wave magmount on the car. Will need to try my Arrow
yagi next time. I copied the majority of the pass from the VERY weak AOS
through moderately strong to the VERY weak LOS. I clearly heard the voice
telemetry and the very end of the English kids message, then a foreign
language kids message. I even heard the distinctive SSTV at the very end
as it was approaching LOS. I will have to download MSSTV and see if I got
anything. Next time, I will remember my audio cord and try to get a better
recording rather than holding the recorder next to the radio.

8/11/2011. I got my first SSTV image from ARISSsat-1 and first
interaction with a satalite. it may have been one way but it a start.
feels like the first QSO I ever had just way cooler. Man was that cool!
Others have got it before and I have seen it but it amost breath taking to
see the image apeer on the screenand know its coming from you radio and
see that MMSSTV is working. I heard faint voice to but could not make it
out. I didnt relize what i was hearing at first so did not hit record,
Next time. Its not that good but it still was cool. Another pass in a
couple hours and a few in the day light. WoW. I fell like a little kid but
