To promote interest in space and radio, the International Space Station (ISS) transmits images to earth using slow scan television (SSTV). These events are announced on the x profile @ARISS_Intl.

With a RTL-SDR and a V-dipole antenna (as mentioned in my previous post), I was able to receive a partial image from the ISS. This is from Expedition 72 - Series 22 Fortieth Anniversary.

I used GQRX to receive the signal and used the FM demodulation.

The image was transmitted on 145.800 MHz using PD120 mode.

I decoded the image using QSSTV. Selecting Options->Configuration->Sound, I was able to change the input to “From file”. I selected the .wav file from GQRX.

Here is the image from QSSTV:

Spoilers! This page here by ARISS shows submittions from HAM operators. People have gotten some great receptions!

I hope to capture more images, this was from a 50 degree pass, so we can do better!

I was able to capture a much better pass of the ISS. Image here:
