The International Space Station has been busy transmitting SSTV or Slow Scan Television images over the past few days, the complete schedule can be found here at the ARISS SSTV blogspot
The same equipment I use to receive the NOAA weather satellites is used to receive SSTV images from the space station with some minor changes to the configuration.
Below is one of the images I received yesterday on 7th December
First I tune SDR sharp to 145.825 Mhz which is the downlink frequency from the Int Space Station. I leave the bandwidth set to 180 K and make sure WFM is selected.
I also change the audio output in SDR sharp sending it to the onboard speakers of my laptop from the normal virtual cable settings used with the NOAA satellites. I am not sure why but have never got MMSSTV to work correctly using virtual cable.
Next is to start the MMSSTV software and under option ensure the audio input selection is the onboard speakers of my laptop.
Click on Option – Setup MMSSTV – misc
Check the Soundcard In box contains the same target you specified in SDR sharp audio out.
Back on the main GUI verify the RX Mode is set to Auto. The Images are transmitted using the PD120 protocol however I have always left it in Auto and not experienced any difficulties.
I usually set the laptop speaker volume to around 50% however yours may be different.
You can use a website such as the awesome n2yo.com to visualize how the ISS will travel over your location at what time
Once the Space Station comes into range of my antenna and MMSSTV begins decoding the signal, this is what I see in the waterfall on SDR sharp
Below are some of the images as they were received during the past 3 days
Thanks for looking
