The AMSAT store is currently offline for some needed upgrades and
should return within a couple of days. If you need immediate
assistance, please call Martha at (301) 822-4376 between 10am and 6pm

OK, so I am crazy, but I have been bashing my brain about using a servo
motor to simulate the human wrist movement of varying the orientation of an
antenna, as done in portable hand-held operation.
As I understand, servos primarily rotate 180 degrees left or right governed
by the control signal. That would accomplish the above requirements of
pointing the antenna and adjusting for optimal signal.
However, and a BIG however, I know zip about servos or controlling them. I
realize too that their would be a antenna weight problem to overcome and
other mechanical factors too!
Consequently, I am wondering it any of you experienced operators have
contemplated this before?

ou seek has already been done. ?AMSAT sells the boards and a programmed
microcontroller for an AZ/EL rotor using servo motors. ?It is very robust
and can take directions directly from SATPC32. ?I built mine and love it.

Just curious. Are you asking about azimuth/elevation type rotation or
are you asking about rotating the antenna around its long axis to adjust
for vertical and horizontal polarization changes?

So exciting, despite the SpaceX setback!
Fox-1A - U/v (FM) - active as AO-85
Fox-1B - U/v (FM) - Launches 2017-03-16 via ULA Delta II
Fox-1Cliff - U/v|L/v (FM) - Launch TBD via SpaceX Falcon9
Fox-1D - U/v|L/v (FM) - Launch TBD via SpaceX Falcon9
Fox-1E - V/u (linear) - Launches 2017-12 via Virgin Galactic LauncherOne
Can't see the AMSAT store because of remodeling (knocking out a wall,
I believe) but is there Fox swag there?

Sorry. I was clear enough with my description. I an not talking about
Az/El rotation, but rotation of the antenna along its axis, as needed when
using a hand-held antenna.
The bird is wobbling and changing orientation which has to be compensated
for by twisting you wrist to get strongest signal. This is not available on
a traditional Az/El configuration, but would be a nice improvement.
Just brainstorming......

Jerry

If you are putting up a whole Az/El tracking deal, you'd probably want
to consider circularly polarized antennas since that eliminates the
need to have to flip polarity.
Are you thinking about for portable use with an Arrow-style dual-band
crossed antenna? Because there it would be helpful.

Hi,
I heard there was interest for a 3D CubeSat model here. I'm a developer of
the PocketQube satellite, SMOG-1. It is a hungarian student satellite
developed at the Budapest University of Technology and Economics. The
mission of the cube will be the spectrum monitoring of the 420-820MHz band
in a low earth orbit. You can get more information here or on our Facebook
page (sorry if advertising ourselves is not permitted here)
The 3D video can be found here: https://www.youtube.com/watch?v=zMzEMR8Gdp8
Feel free to share it with those, who might be interested!
Cheers,
HA4TI Tibor

Andrew,
I think I read your email too quickly. What I sent previously isn't what you
want.
This is actually what you need.
Go to: ? dishpointer.com
-Input your location-Press GO-Select INMARSAT-It will show you a directional
pointing map.
