OOPs.  Just noticed how big those files are!    Like 6 GB!  I have a monthly bandwidth of 10 GB here, so can't download that without buying more bandwidth.  I can take my laptop over to the nearby library where they have free wireless, but that would take me several hours parked outside in the cold. I'll have to calculate how long it should take.  I might be able to download it here at home in the middle of the night when we have another 10 GB of free bandwidth that we seldom use because we're never up at night. 
   Either that, or just pay a few $s for some extra bandwidth this month.

The app looks like this it put the Awips II Cave and Awips II AlertViz under my programs, I'm not sure what the AlertViz is?
If you can see in the pic it asks for a http://localhost:9581/services.
I was hoping I could just open your .txt file you posted above.
I'll try what you mentioned using tsreader also need a better lock on that signal.

I was on my way up to the store and realized I need to quit saying that it's asking
I can type whatever I want in the spaces provided I think that's just the default numbers it puts on there
Anyway I imagine once I get the right address on there maybe Something like a browser would open up so you could look at other things

I'm guessing that AlertViz is probably a program that filters and finds weather alerts like tornado warnings, etc.

Re the 9581/services, I don't know.  The 9581 might be one of the other source or destination port #s from the raw stream, or it's possible that it's expecting the products to be rebroadcast on other port #s,  or it's possible that once the stream is detected, this program becomes a server that rebroadcasts the various products it detects in the stream.  This is starting to sound like problems I ran into the 2nd time I tried installing the Linux thing from unidata or ucar or whatever it was.  After compiling, it seemed to be expecting my network to be different than it was.  My network is in the 10.1.x.x range, and it was expecting something different, and was looking for things in ranges it didn't have access to.
But hopefully, once you get a stream feeding, this windows version might figure things out by itself.  I saw some mention of configuration files at the site. It may need some significant editing of the configuration.
   Thinking selfishly here.... hopefully you'll figure it out before I get the files downloaded.  [smile]

Well, I thought before I try a satellite connection like we're thinking, maybe I should see if this program works or how?
So I found this page its not the same software I'm using but, I needed a server address to put into the box.
And this is just for testing.  http://edex-cloud.unidata.ucar.edu:9581/services 
Its in this link.
http://www.unidata.ucar.edu/software/awips2/doc/install.html

I called my connection Microsoft (were it has a place for a name) I guess I could of called it anything 

Then after that, the Cave program was complaining about my local host that it needed in the "alert server" field area. I tried a couple of things then realized it wanted an address and a port.
So I opened a command prompt typed "netstat -a".. found a local IP on my computer that was 192.x.x.x:123 (listening) not sure what was listening on there.[smile]
That worked!


It complained with pop up errors (I just clicked OK) a few more times after I clicked "validate" and clicked "ok" about the connection, I waited a minute or so and the AWIPS emblem( in the middle of the screen) had a green status bar moving across.
Then this map popped up its just a test but I hope this helps. And I hope it doesn't have certain addresses it only accepts.

Looks like it wants some kind of DVB-S to IP server; maybe that could be simulated with netcat or similar on Linux.

Forget what I did in my above post about the local ip it was complaining about.

But
Start the AwipsII AlertViz first using the "test address" I posted above.
An AlertViz status message bar will pop up. 
then start the Cave program using the same "test address" and leave the "alert server" field area just like its default (localhost:61998)
The program Starts up with no errors.

I tried the signal yesterday I couldn't get it no way
I could get it last year when it was only 8PSK

But I don't think this program is going to work I thought it might
Now that I read most of the whole book on the network
If anything might be able to open a picture with an app

Seems like you should be able to have it connect to an internet feed of the NOAAPORT data.  I've read about a few of those, but I forget where, plus I don't have any idea of how to do that.  I'm guessing that it would be similar to what you did with your test URL.  Maybe google NOAAPORT FEEDS??

Re getting the signal, that signal is weak here too, and I'm not getting it 100% by any means, but it seems like it's coming in better than I expected considering it's 16APSK.  Crazyscan reports about 10.5 on the SNR, which I didn't think was good enough for 16APSK at 2/3 FEC, but it shows a zero BER.  It does have occasional errors in the text products, and occasional continuity errors show up.
   If my aim is off, and the SNR drops below 10, I tend to lose it.  I've been meaning to try to tweak my aim, but I haven't had the time yet.

  Yesterday, I was meaning to go through all the PIDs, and use wireshark to give me the port numbers for the different PIDs, like I had done Fri/Sat, however for some reason, I couldn't get wireshark to work at all yesterday (haven't tried it today).  I'm more comfortable using ethereal, where I would enter a filter specifying a host IP#, and it would just give me only those packets of interest, and I think I was doing that with wireshark too.  But yesterday, I couldn't get wireshark to accept the "host {IP#}" command at all. Kept giving me an error.  In addition, I couldn't get TSREADER's rebroadcast to show up at all in wireshark at all, even with no filter.  Almost like the multicast packets weren't showing up on the interface I selected.  I'm half wondering if my playing around with that TBS-IP program messed up the TSREADER rebroadcast function. 
    Anyway, nothing has been working right the last couple days with respect to this project.

Should require about 9 db SNR, so that explains why you get it pretty good.

Thanks.  I was too lazy to look for that page that shows the minimum required, and was just going by memory, but I guess my memory was faulty again.  [smile]  Thanks.

You might take a look at Weather Message software. It does emwin from internet or satellite plus noaaport.

Thanks Racom, its free for a month I see. Might see what its like.


@wejones If you find a file you think might be a Sat image. It might be I think?  a .hdf file
or hdf4 or hdf5. I found a HDF viewer for free on the internet. 

The data being sent might all be wrapped up inside a .xml file. Like the text file you posted I saw
<?xml version="1.0" sG Étandalone="yes"?> <site xmlns:xsi="http://www.w3.org

So, maybe a radar might look like...

<?xml version=”1.0” encoding=”UTF-8” standalone=”yes”?><requestPatterns xmlns:ns2=”group”>regex>^SDUS[234578]. .*</regex><regex>^Radar.*</regex></requestPatterns>

and satellite might look like...

<?xml version=”1.0” encoding=”UTF-8” standalone=”yes”?><requestPatterns <requestPatterns xmlns:ns2="group"><regex>TI.... ....</regex></requestPatterns>

 The TI would be short for example TIGE04 KNES.


I read this from a Ucar  Systems manual pdf  yesterday.
If you get at it again. thought I'd share before I forget the info.

ADDED: I have a sample of a (image) .hdf file it might look like this but, alot bigger of course

Code:

‰HDF

  Re not locking the transponder, you might try it again, perhaps tomorrow morning.  This morning, the transponder was giving me about 11.3 dB SNR, but it's dropped a bit, and is back to about 10.6 now, although the TBS Data program is showing 98/77 for S/Q.  It may just be my local conditions are improving though. A week ago, there were still a few leaves on the oak trees here, but they're pretty much gone now {seems like they all ended up on my driveway}. 
   Not sure if it's a cooincidence, but that TBS IP Data program was working fine this afternoon.  Got it to retransmit one PID at a time out so I could monitor it with wireshark.  I tried it on PID 102, and it sat there idle for a while, but then started spitting out data, and then stopped, and then started up again.  I'm guessing that between the stops it was transmitting some graphics.  The NOAA chart on post 11 said PID 102 had GOES data.  I used to download GOES images from the old APT GOES-TAP service that was in FM^2 mode on some sat around where SES-2 is now.  I had a special computer card that turned the APT audio into images. Pretty neat.

Thanks I might try it again or I could go down to my brother in-laws house There's a 10 footer.
I don't think I can get it on my 6 footer. I could when it was 8psk

I found a recording from this signal, I never deleted from last year on my computer.
Not sure what pid it was from.  
RE the netcdf4 you mentioned,  I'm going to try the netcdf4 install  and try it out on the recording I have and see how that goes (knock on wood) can't just install the netcdf4 only. 
There's some utility commands in the netcdf4 looks like? that I can do from the terminal
But I haven't got that far yet (I'm on step 5) of the install jumping hurdles.
