[amsat-bb] ISS SSTV

[John Brier]

I believe they use an unmodified Kenwood D710E for SSTV and it can put
out up to 50 watts.

FWIW, up until the July 2017 event I believe it was always PD180.
Perhaps they will stay on PD120 going forward. I think I preferred the
higher resolution mode, but certainly PD120 makes it easier to get
more and more complete images.
