Decoding NOAA downloaded passes


#1

Hi there:

Is it posible to decode the downloaded passes with wxtoimg?
I tried, but is not possible to process the images. I always an error message and the end of the auto-process

Have you tried putting your SatNOGS station in Stand alone mode. Start the TCP server then connect to it via TCP from another Gqrx or SDR# and piping that audio to WXtoimg?

I just use another SDR plugged into my PC.

Thanks Bob…

I have no idea about a tcp server inside satnogs.

Is there any tutorial about standalone mode? I need to deepen inside this subject…

Juan there is a Satnogs Tab called Wiki you will find good info there. Go to your Raspberry PI IP address port 5000. something like 128.0.0.1:5000. Use your browser. Yours will be different. Top right hand side is a blue button which will switch between Network and Stand alone mode. You would have to install rtl_tcp In Linux sudo apt-get install rtl_tcp. same way you installed SatNOGs programs

Thanks Bob, I’ll give it a try this evening

What did you try? It should be possible to process SatNOGS passes with wxtoimg if you to download the audio recording from a NOAA pass, convert it to a format that wxtoimg understands, then process it with wxtoimg. I don’t remember the precise audio format needed by wxtoimg but think it is described in the user manual.

I tried sending the audio (through vac) directly from the web browser to wxtoimg software. Signal is ok, everything works fine, but at the end of the recorded pass, when I select “auto-process” on wxtoimg, gives me a red message (I don’t remember exactly)

Thanks
