I want to thank's Glenn AA5PK who provide me with the antenna manual. When
reading it i discover something new "axial radiation" the
matching line can be made for LHCP and RHCP using RG-59 and RG-58
combination for delay/matching lines and two RG-59 for delay/matching
lines to produce this "axial radiation"? Is this gives both horizontal and
vertical polarization at the same time? If it's the case it's
could be a way to counteract the polarization change eg; having to manually
rotate the antenna. Just note they don't called it
"polarization" but "axial radiation"
Google give me a lot of return but all related to helical, helix antenna as
this one:

That's what i like in the hamfest you always stumble on odd things this
antenna matching harness is made for axial radiation just hope they
are not harmful like the gamma rays on humans :)

I am sure no American firm participated.

We are shooting ourselves right in the derri?re with ITAR. I am also
certain White House is much too preoccupied with other things to deal
with it.
As proof that ITAR has completely outlived its usefulness, I give this
example:
http://www.nytimes.com/2009/08/30/science/space/30india.html?ref=space
India, denied access to nearly all of our space technology here in the
US and even put on denied access lists, simply goes around us and helps
other nations build technical capabilities and then orbits the moon with
a probe. Our involvement? Continued shooting our industries and
technical status in the derri?re.

I made one and am open for offers to change anything
I have it running at home at the moment, and have a server to migrate to

All of that information is available to you, just in 2 separate locations.
The sat name, launch date, frequency/mode, and keps are all at the amsat.org
website, and the activity can be found at oscar.dcarr.org. As far as getting
the information updated on these sites with the new satellite, you must
remember that they are both volunteer run, and the updates have to fit in
the schedule of the volunteers who run the sites.
