Hi!
I was at the
Yuma Hamfest in Arizona for the past couple of days, and had a chance to copy one ISS pass this morning around 1600 UTC. I used my TH-D74 & Elk log periodic antenna to receive the transmissions. Not only did I record them with the TH-D74, I also had the Robot36 Android app on my phone to decode the signals in real time. I downloaded the app about 20 minutes before the pass, but didn't do much other than find where I could specify the SSTV mode as PD120. The first picture was chopped a bit by the app, but the second picture was decoded perfectly.
This is how the Robot36 app looked, after the complete picture was received:
The picture by itself, from the Robot36 app:
After the pass, I took the WAV file from the TH-D74, converted it from a 256kbps WAV file to a 48kbps WAV file, and then ran the 48kbps WAV file through QSSTV on my Linux laptop. The recording had both pictures. The first picture:
Then the second picture, the one I received using the Robot36 app, decoded by QSSTV:
Looks like QSSTV was able to straighten out the text below the picture of the Columbia launch, where the picture from Robot36 shows some slanting in that text - a visual indication of the Doppler effect on the signals from the ISS.
73!
