Re: Possible ISS simplex operation, m




Hello miles and thanks for the post.
Do you know if one of the antenna ports will support Ultra-HF?
As I recall, the antennas were installed in a prior spacewalk.
I looked for equipment info on the amsat and RAC websites but could'nt
find.

I'm all set and educated basically for SSTV, thanks. 73, pat
