The International Space Station SSTV transmitter was setup and activated from April 11 – 14 2016. Although it’s flight path over the U.K was not great from my location ( Lincolnshire U.K ) I was still able to receive some SSTV images shown below;
These were received during the pass at around 20:30 ( UK time ) on 13th April 2016
Here is a link to a short YouTube video I made of the live ISS SSTV transmission on April 13th 2016 during it’s previous pass https://youtu.be/Ng0krWe4O14
It will give you an idea of what the transmission looks and sounds like.
The equipment I used was as follows;
A Turnstile type antenna tuned for 144 MHz that I normally use to receive Funcube satellite telemetry
The SDRplay RTL dongle connected to my laptop. Here is a link to this awesome little device http://www.sdrplay.com/index.html
I used the highly recommended MMSSTV software to decode the signal available here http://hamsoft.ca/pages/mmsstv.php
The RTL radio software used here was SDR# wich is available from here http://airspy.com/download/
I just tuned to the frequency the ISS transmits the SSTV signal and waited for MMSSTV to start decoding the signal and producing an image. The frequency I started at was 145.803 MHz however this will need to be manually tweaked over the period of transmission because of Doppler shift. It may be a little higher than this as the ISS is moving towards you. Set SDR# to FM wide mode.
Routing the sound from SDR# to MMSSTV can be troublesome, I installed Virtual Audio Cable but could not get this to work very well with my laptop. I just routed the SDR# sound output to my laptop speakers and set the MMSSTV input to the speakers. It worked on one laptop but not on another, I still don’t know why.
I highly recommend you save the recorded SSTV signal to your pc using whatever audio recording software you use. This way you can always play the audio file back into MMSSTV and retrieve your images if something goes wrong during the live capture.
Thanks for looking.
