[amsat-bb] NASA on the Air images with MMSSTV overlay?

[John Brier]

So I hadn't seen this image yet:

Clearly that is not the template. It was just a choice to make RS0ISS
larger. I believe it is the Russian equipment and these events don't happen
without them so it makes sense to me. I dont think all the images have
NA1SS in them but I'm pretty sure they all have RS0ISS in them.
