Reuse on the Fox Sherpa flight would be cool, but the rocket is on the wrong
coast. We're launching from Vandenberg in California.

Paul et al,
Thanks for the link. Apparently it IS as difficult as I thought to do it as
sea. If I were on the
welding team, I would be looking over my shoulder at the rocket, just in
case. :) It will be
interesting to see what they do once this moves from proof of principle to
operational. Being SpaceX,
it will be undoubtedly innovative and efficient.
73s,
Alan

All the wonderful space stuff aside, the most fascinating thing about this
to me is that everyone in the aerospace industry said it couldn't be done
and it was a stupid impossible idea. So SpaceX just proved everyone
wrong. Watching the failures and seeing that each new attempt was closer
to success than the prior ones was a study in tenacity. Elon Musk is one
heck of a visionary, and he is not afraid to fail very publicly.
My father told me that he was sorry for my generation and those that
followed. All the important "firsts" had already happened during his
lifetime: flight, telephones, radio, TV, computers, spaceflight, etc. We
were doomed to just do things better/faster/cheaper. Perhaps he was right,
but that process of refinement is what makes things useful. What amazing
times we live in.

Hello,
Have been monitoring the link budget discussion and have questions about
polarization. Unlike the 2m and 70cm LEOs, I assume the spacecraft will be
stabilized with a fixed polarization and not susceptible to Faraday
rotation. What polarization is planned for the satellite for up and down
link and do we need to start designing polarizers for the link?
Keep up the great work!

Bob

Mike,
That's good news as +16 dBm is 40mw and not 200mw as I previously
wrote. So one could use a standard transverter with the amp for
terrestrial 5-GHz. The satellite ground station will have integrated
SDR transceiver for digital modes, being discussed by planning
groups. That will also be good news for the average satellite
operator since it will eliminate having to scrounge up surplus mw
gear and "roll your own".
1m ku-band offset feed dishes are the "norm" for home satellite here
in AK so the antenna should not be hard to get. Az-el may require
some ingenuity; I'm thinking reuse of small telescope tracking drives
which will have necessary finest of pointing.

Everyone,
This has been tested already. A fellow ham has done it and shared
findings with me. The 600 mW drive is with a pad still inline on the
input. If you bypass it, drive drops to 10-12 dBm range.
The devices used are from Skyworks. SE5004L. There are two in push/pull.
We have been discussing this amp on the phase4ground list for use as a
test bed.
Ed, this would make a very nice amp for portable 5760 use.

ABOUT ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), and the National Aeronautics and Space
Administration (NASA). The primary goal of ARISS is to promote exploration
of science, technology, engineering, and mathematics (STEM) topics by
organizing scheduled contacts via amateur radio between crew members aboard
the ISS and students in classrooms or informal education venues. With the
help of experienced amateur radio volunteers, ISS crews speak directly with
large audiences in a variety of public forums. Before and during these
radio contacts, students, teachers, parents, and communities learn about
space, space technologies, and amateur radio. For more information, see
www.ariss.org, www.amsat.org, and www.a
rrl.org.
Thank you & 73,
