Would anyone be able to suggest a good 9600 bird I could use for testing?
Something that stays on for a whole pass?

Hello, can I ask a question related to this several-years old thread? At
George Washington University, this fall we will be on the air and are
buliding up an amateur radio club ground station from scratch. Currently we
are collecting equipment, cables, etc., while we wait for the construction
to begin on a new door in the interior of a third floor class room space to
let us use that area as a "radio room" or something like that. At my home
QTH, I'm testing out the radios we can use, and would like to both receive
and transmit - with omni antennas (e.g., eggbeaters, QHA ) and later AZ-El
yagis.
Assuming an LNA is used at the antenna for the RX path, would it be
practical to use that same omni for uplink? What are the recommended power
settings for such an uplink for any of the recent amsats?
If there was a constraint (for the summer into fall) of operating in a
limited visibility area, and approximately 50 sq. ft of open access (i.e.,
21 ft monopole mast with open free area about 4 ft dia.) would that be
adequate for any sort of uplink antenna? The good thing is that the
ultimate location of the club station antenna farm is huge, but for now
this is what we have. I'm open to AZ-El positioners but the mast loading
limit is pretty small for now.
Any suggestion welcome.

Samudra N3RDX

Hi Samudra, consider a better alternative to the 'egg beater': Moxon
turnstile....much better performance. I will e-mail the article from qst.
Also, consider an Elk 2m/440 yagi at a fixed elevation and on a Radio Shack
rotor.

Yes, I considered LMR-400 and above, but due to the rigid bending limits of
those cables, I went down the scale to LMR-240 for this first install, the
cable is almost as flexible as RG-58/59 etc. ...

I was actually reading up on Bob Bruninga's analysis (earlier in this
thread) of why a fixed elevation yagi would have more than adequate
performance for majority of the LEO passes, when you sent me the info
below. Thank you!
Comment: based upon what you sent in a separate message, the picture of a
"mean" looking in-service 5-element model, if the antenna is that small of
a mass, a second revolute joint for Elevation control with positioner could
be practical - if some parts from hobby robotics / class room robotics
projects were able to be used. Of course it would increase the cost
somewhat and complicate wiring - but would result in true elevation over
azimuth control.

NASA TV COVERAGE FOR SPACEX DRAGON REENTRY AND SPLASHDOWN
HOUSTON -- NASA Television will provide extensive coverage of the
departure of the SpaceX Dragon capsule from the International Space
Station before its reentry and splashdown on May 31.
On Wednesday, May 30, a news briefing previewing the departure
activities will be held at NASA's Johnson Space Center in Houston at
9 a.m. CDT (10 a.m. EDT) and will be broadcast live on NASA TV and
the agency's website. Participants include NASA Flight Director Holly
Ridings and SpaceX Mission Manager John Couluris.
On Thursday, May 31, NASA TV will begin live coverage of the departure
of Dragon at 2:30 a.m. CDT (3:30 a.m. EDT). Coverage will continue
through the release of Dragon from the station, currently scheduled
for 5:10 a.m. CDT (6:10 a.m. EDT) and will resume at 9:15 a.m. CDT
(10:15 a.m. EDT) with deorbit and splashdown coverage. The capsule is
currently scheduled to splashdown in the Pacific Ocean at 10:44 a.m.
CDT (11:44 a.m. EDT) hundreds of miles off the west coast of
California likely out of range of live television.
A news briefing will be held jointly from Johnson and SpaceX in
Hawthorne, Calif., at 1 p.m. CDT (2 p.m. EDT) live on NASA TV.
Media representatives can participate in person at Johnson or via
telephone by calling 281-483-5111 at least 15 minutes before each
briefing. Media badges from Dragon launch activities at NASA's
Kennedy Space Center in Florida will be honored at Johnson through
splashdown.

Hello,
I tottaly agree with Ted, i have a single moxon (not turnstile) for VHF LEO
satellite and works quite good. Also i have another, a moxon turnstile for
436 LEO satellites and it work relatively fine, but average gain is only
good enough for SSB satellites. For FM reception a good LNA is mandatory.
Right now i don't have any LNA neither for VHF or UHF (that's why I always
work AO-27 with my arrow antenna). I can tell you that even a single moxon
is almost enough, at least for VHF, for UHF the signal loss is greater so
the incoming signal is not enough for FM, but i can at least hear and see on
the FFT spectrum display any SSB or CW, they usually show up with at
least10dB over the noise background.
The moxon are greats but a good LNA just after the antenna will be very
helpfull. One more thing, for a smoth recieving pattern is better to put the
antenna close to the roof, this avoid the nulls and fadings but compromise
the reception at low elevation angles.
Well, that's all. Just my little experience with these great antennas.
Good Luck all,
73!!!
Raydel,
CM2ESP

Congratulations Steve, W5IEM, on your first satellite contact. I will
never forget my first one. It was more exciting than my first novice
contact when I was 11 years old! You will soon find out just how
addictive satellites can be. Welcome aboard!
I would like to pass on my "Thank You" to everyone at the AMSAT booth.
I worked in the booth on both Friday and Saturday. It was so nice to
put a face on the many I have worked through a satellite. This was my
first time to work in an AMSAT booth. Everyone made me feel so much at
home. The hospitality that I was shown was very much appreciated. The
time just went way too fast. The banquet was terrific too. Learning
about the Fun Cube Dongle was a special treat. A big Thank You to
everyone involved for making my first trip to Dayton a special one. A
Thank You also goes out to Martha for making my reservations at a really
nice hotel.
Like satellites, I believe Dayton may be habit forming! I have been an
active Ham for 50+ years and I am still learning new tricks and
developing "good" habits.
73,

A good 9600 test signal from space is RAX-2.
Each 10 seconds its transmits a short burst.
Relative easy to receive.
