Astronaut Scott Tingle* talking to Pinson Valley Highschool students
on April 10th, 2018. This is a quick edit mostly so the folks in
Alabama can see what it sounded like from a completely different
place. I received this in downtown Raleigh, North Carolina, at the Red
Hat parking deck, where I work.
I missed the first half of the contact because it came in range of me
after it was already in range of the school. I also missed a good
portion of my pass due to a big building downtown blocking the signal.
At the end since it was still in range of me after it went out of
range for them, I may have received some transmissions from Scott that
they missed, or at least with less noise.

* Ricky Arnold was scheduled to talk to the students but I'm almost
certain this is Scott Tingle who has been doing a lot of ARISS
I have a like new Wouxun KG-UV9D dual band full duplex HT that I am not using. and would like to sell !! Great to work the U/V satellites like AO92 Ao91 and AO85. Comes with complete accessories when bought new. If interested I have plenty of pictures to show. Email me at ingejack(a)cox.net mailto:[email protected] for details. Thanks JACK KC7MG
Many radio amateurs are familiar with tracking amateur satellites
that orbit the Earth in low orbits or high elliptical orbits.
Several tracking programs and all required orbital parameters are
available for tracking these satellites.
But soon spacecraft carrying an amateur radio payload will be
launched towards the Moon and beyond. If amateurs want to track
these spacecraft they will need suitable tracking software and
orbital elements to be able to calculate the positions of these
Unfortunately none of the currently available tracking programs,
used for satellite tracking by amateurs, is suitable for deep
space tracking. But fortunately two free, open source software
packages for Windows, Linux and Mac are available, that will
enable deep space tracking:
General Mission Analysis Tool (GMAT)
SciLab, including CelestLab, CelestLabX and Aerospace Blockset
Probably most amateurs will prefer GMAT, because it is most user
friendly, has a lot of documentation and help files, and contains
many sample scripts. Scripts that are created by other amateurs
can be used without having much knowledge or experience with
It is not certain that orbital elements for all deep space spacecraft
carrying amateur radio payloads will be made available to
radio amateurs. Therefore amateurs may need to measure these
orbital elements themselves through doppler and ranging
measurements. So amateurs will need to set up their own Amateur
Deep Space Network, similar to NASA's DSN, ESA's Estrack, etc.
This will require some stations with large enough antennas and
with equipment to carry out doppler and ranging measurements
to determine direction and distance to the spacecraft. This new
development is an interesting challenge for radio amateurs.

You can find further information on space flight on this very
informative set of pages:
Deep space navigation is covered in chapter 13:
My local radio club here in Irving, TX prevailed upon me to do a
presentation for our April meeting in a week. "I'll do it on satellites" I
I wondered if I could get any recommendations/permission to use a recent
basic introduction to satellites PowerPoint presentation. You will get
credit I promise. I just don't have the time to reinvent the wheel.
Response off list would be just fine.

great fo29 pass a few mins ago.
next pass ao92 at 1434z
we are attempting all visible passes to the west or overhead today on
ao92, fo29, so50, ao85, ao91 and will give ao7 a shot at 1744z.
working on the possibilty of europe this evening on 7 or 29 but have some
hills to the east
about the only hf working at all is ft8 on 30. prop gods not happy.
