recieving SSTV from ARISSat-1

Jim Cameron
 

I always wanted to try SSTV. So here is a good chance.
 
I don't have a fancy recieve interface, what I am using is a Icom  IC28H with a diemound 510 dualbander feed by RG8 ant 50 ft.
 
I am using AMSAT perdict to track ARISSat-1. and MMSSTV software to recieve SSTV . LIke I said my "homebrew" recieve interface is a cable that goes from the speacker out in the back of the radio to the line in on my sound card. I also can put a small mic next to the speacker I have pluged into the back of my IC28H that goes to the line in on my sound card. Some  web sites say use the line in on the sound card others say to use the mic in, is there really a diffrence? As long as my PC can "hear" my radio I think I am good. thoughts?  Does any body know if there is a way I can test the way I set things up "before" the next pass? That was I would know things were working. I did look in HRD and I dont see ARISSat-1, Thanks for the tip Les.

Finally received two images from ARISSat-1 ...
Outstanding!

... do I really need the squelch turned on or do I really need it to make noise all nite?
Although grounds for divorce in some states (grin), we ARE talking about a weak signal from 2-500 out there ... How about just turning the volume down - but keeping SQ open!

Finally received two images from ARISSat-1 last nite after I went to bed. I am using HRD,SIGNALINK-USB and 2m/70cm Arrow J-pole mounted about 20Ft up. Had the IC-746Pro set on freq with the squelch turned down so it was just making static. Volume set low, and just left the laptop running the HRD program. Question, do I really need the squelch turned on or do I really need it to make noise all nite?

Hi Chris!

 

How about before the Keps. For that satellite were added to the downloadable file?

You don't have too enter any keps. In Orbitron, make sure you have the box checked next to Radioskaf-B,

click on the little crossed hammers in the main menu. A new window will open. click "update TLE", then click on the little globe on the upper right of the window. Orbitron will load the latest keps for all the birds(including  ARRISat-1)from Celestrak.

Wow, great pass over western Oklahoma, long pass and 70 degree elevation copied the bird out over the gulf. Lost it just as it was approaching the NW tip of Cuba. Twin mirrored J-Poles @ 40' but the bird is definitely tumbling, got to get to work on a small RHCP crossed Yagi.

Re: Juno and ARISSat-1 Keps

Sorry, I was doing that from memory, they are not crossed hammers, it's a hammer and a wrench crossed.
And it's not "Update TLE", the button says "TLE UPDATER".
Just copied several packets from ARRISAT-1's last pass and didn't have MSSTV running.

Here is the link:  http://antoninoporcino.xoom.it/VoxRecorder/
I havent tried to get it to work yet.  Looks like you have to set up your Windows soundcard to record, which is something I don't know how to do yet.  Will have to figure that out.  I'm betting it won't work while MMSSTV is using the soundcard.

ARISSat-1 SSTV

Hi Les,
 
Welcome. I to am trying to get SSTV picture. I will be using Hamradio deluxe's SSTV software and it's tracking software. I just like it because its all in one program. I haqd to redownload HRD but once it's done and reinstalled. I will being trying. I will be using my IC28H and my antenna is a diemound 510   2 meter 70 CM  dual bander at 50 ft. I was wondering how well it could be done with a vertiail antenna thanks to you I know it can be done.
I never thought of leaving the SSTV software running in the background with the radio hooked up. I will try it with low volume as see what happens. thanks fir the link to the picture. I also dont have SSB. ITs a bummer I know but there is a hamfest next week end maybe I will find one.

Just joined the group, and received my first good SSTV picture this morning, 8-6-11.  time 13:38Z.  QTH Madison KS, Grid Square EM18wd.  This was only the 2nd or 3rd daylight pass since I have been trying for a SSTV pic.  Makes a lot of difference to have the bird in full power mode!  This proves that you can get a half way decent picture using minimal equipment.
 
My set-up is:  Software  MMSSTV + Yaesu FT-7800 Transceiver + Antenna Arrow dual band J-Pole up only 10 ft.

I keep MMSSTV running in the background connected to the audio output of the FT-7800, and received this picture while still sleeping.  I've used the same technique to receive pictures from the ISS in the past.  I'm sure the picture would be a little less noisy if I had a directional antenna pointed at the bird, but this proves that you can get decent pictures without any special antenna or equipment.  The picture can be seen here:
https://picasaweb.google.com/denalidude/ARISSAT1SSTV     The next daytime passes are Sunday morning, and I hope to get at least one more picture, and/or some voice telemetry or messages.  Since I don't have a VHF ssb transceiver, I can't do the PSK telemetry.  It sucks to be poor!  Hi Hi

... how well it could be done with a vertiail antenna ...

Just know the "pattern" of a vertical - essentially, the transmitted and received signals are best accomplished when that vertical is perpendicular to your target. SO - an GREAT pass for others with handheld Yagis won;t be as good for my neighbor with a vertical on the chimney - because directly above a vertical can be darned near a "null" point.

If your vertical is within reach, angling it so that it "hits" the sat's orbit makes for a better contact.

Keep us informed - what a great week for experimenting!

Forgive me if this has already been posted, as I just joined.  Even if you prefer your own tracking program, it is easy to track using the AMSAT tracking, which now has ARRISSat-1 in the database.  I usually use HRD Satellite tracking, but the last time I checked, it still doesn't have ARRISSat.  AMSAT  tracking can be found here:   http://www.amsat.org/amsat-new/tools/predict/ 

The ARRISSat-1 website also has tracking. http://www.arissat1.com/

The problem is: When I cut and paste Keps from another source the program I use won’t read them unless they are in the proper columnar and line position, just like the two-line Keps are supposed to be. Without posting a copy of the two-line table that is my best explanation for the problem.
