EMike,
More a case that if you have one problem, there may be no solution, but if
you have multiple problems they may solve each other.

Hum,
Don't know what the thought of viewing AO-7 caught my attention, but it
did. So I did some quick math:
In round numbers AO-7 is about 0.06 arc seconds across (1450 KM orbit, 0.4
meters diameter). That's the theoretical resolving power of a telescope
with a 16,000mm focal length and magnification of about 500, constructed
with perfect optics and operated in a vacuum. So I wouldn't hold my breath
thinking you can observe it with a ground based telescope.
But maybe as a point of light? N2YO.com doesn't even list a magnitude for
visible passes.

Besides seeing the satellite - I've seen several zip through the field
of view in my telescope - tracking the object, even if you knew it was
coming (and which one it actually was), would be very difficult. Way
too fast for regular astronomical telescope mounts. And, yes, point of
light is all you'd get.
We have had (very) limited success with doing a manual track of the ISS,
during a visible pass. We used a Dobsonian scope with a Telrad, and a
low magnification eyepiece. One person does the tracking, arm wrapped
around the OTA, while the second person tries to look through the
eyepiece to see the Station, as the whole thing is moving around.
Amazing when it works, but requires practice and some luck.

All,
This Tuesday, Wednesday, and Thursday we will be enabling the camera on
AO-92 on the morning passes over the US east coast. This is in support of
two different educational programs running this week. Please help us copy
images by enabling Auto or High Speed mode in FoxTLM and enabling data to be
uploaded to the server. Camera mode runs for 45 minutes each time, so this
will be an opportunity for Central and South America as well. Images will
appear at http://www.amsat.org/tlm/fox1d/images/ in near-real time.
Thanks for your cooperation.

Hi all-
I'll be hitting the road this weekend, celebrating my birthday by driving
through Vermont and New Hampshire. This will be a holiday-style trip with no
real agenda, taking my time. I won't be on every pass, but I'll be on
several. I'll be on SSB/FM passes.
Saturday 7/14: CT/MA/VT: FN31/32/33/34/44/45Will spend the night just south
of the FN44/45 grid line and will make a point of being on to hand out FN45
from ~2100z Saturday to ~1300z Sunday.?
Sunday 7/15: VT/NH/MA/CT: FN45/44/43/42/31There is a chance I'll be on from
FN41 Rhode Island as well.
Will be on SSB and FM. Follow me on Twitter at @?????????? for real-time
pass info.
Hope to work you this weekend!

AMSAT News Service Special Bulletin 190.01
>From AMSAT HQ KENSINGTON, MD.
DATE July 9, 2018
To All RADIO AMATEURS
BID: $ANS-190.01
On July 9, 2018, AMSAT filed comments with the Federal Communications
Commission on their Notice of Proposed Rulemaking In the Matter of
Streamlining Licensing Procedures for Small Satellites (International
Bureau Docket #18-86). AMSAT's comments as filed can be found at:
https://www.fcc.gov/ecfs/filing/10709067911864
(A copy of AMSAT's comments document can be accessed on the ECFS
page, using the Document Download link)
In the comments, AMSAT reviewed the significant contributions made by
the organization and the amateur radio community. The comments note
that the many scientific and technological achievements made by AMSAT
satellites directly led to many groups, including government,
non-profit, and commercial organizations becoming interested in
developing small satellites of their own. AMSAT also discussed the
suitability of authorizing certain satellites built by universities
and non-profit organizations in the amateur satellite service and
expressed opposition to satellites licensed as experimental under Part
5 of the Commission's regulations operating in the amateur satellite
service bands.
Interested parties may file reply comments on or before August 7, 2018.
[ANS thanks AMSAT Executive Vice-President, Paul Stoetzer, N8HM for

Content-Type: text/plain; charset="UTF-8"
I?m having a problem with my RAS rotor at my winter home. When I turned it
on yesterday, after an absence of about 2 months the elevation went into a
complete backflip when powered up, and is jammed against the roof with an
elevation reading of 195 degrees on the control box. I?m at my Florida home
for just a few weeks to do some fishing, so before starting to work on it to
maybe speed up the repair process a bit I?m asking here if anyone else had
this problem. When the roof dries off I plan on going up there and remove
the antennas before trying to move the rotor, to diagnose. Right now the
azimuth will turn, but the elevation is stuck, it wont move up or down. I?m
hoping it is just jammed into the roof, once unstuck hopefully all it would
need is a re-calibration. Thanks for any useful information....

Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned at the Space
Port Area Conference for Educators (SPACE), Kennedy Space Center, FL with
participating students from Burns Science and Technology Charter School in
Oak Hill, FL. on 13 July. The event is scheduled to begin at approximately
14:00 UTC. It is recommended that you start listening approximately 10
minutes before this time. The duration of the contact is approximately 9
minutes and 30 seconds. The contact will be a telebridge between NA1SS and
W6SRJ. The contact should be audible over the west coast of the U.S.
Interested parties are invited to listen in on the 145.80 MHz downlink. The
contact is expected to be conducted in English.
Burns Science and Technology Charter School is a K-8 public charter school
operating within the Volusia County School District. It is a tuition free
school, with an open admission policy. It is located in a rural area in the
town of Oak Hill, Florida. The school is a STEM school, offering core
curriculum, with emphasis on science, technology, and 21st century skills.
The school has a strong belief that in order to prepare students for success
in the 21st century, today's learners must be able to think critically and
creatively, work collaboratively, and master an ever-growing arena of
skills. The school has 450 students, 25 classroom teachers, seven special
area teachers, and two teaching assistants. The school's mission is to
cultivate learners and leaders who are inspired, able, and prepared to make
a positive difference in the world.
Participants will ask as many of the following questions as time allows:
1. What is the most valuable item you've ever found or discovered in space?
2. What experiments or items do you think would best help astronauts aboard
the Orion spacecraft on the trip to Mars?
3. Do they allow you to bring any lucky charms aboard the ISS? What did or
would you bring as your lucky charm?
4. In 12 years, do you think you might get to go to Mars in the Orion MPCV
for EM-2?
5. What do you want to do as soon as you get back home?
6. How does CIMON stabilize in antigravity? And, can CIMON be used as a Wi-Fi
hotspot for games?
7. Does CIMON have the capability to monitor air quality (gasses in
particular), and are there multiple air quality sensors throughout the
different sections of the ISS?
8. Yesterday was my birthday, how many birthdays have been celebrated aboard
the ISS?
9. Will absolute zero ever be accomplished in the ISS, and if so, will the
cooled atoms in the CAL have no motion at all; creating a wonderful
opportunity to observe and experiment with quantum physics?
10. What does it feel like wearing a spacesuit? Have there been any special
suit modifications for astronauts who are more sensitive to having things
touch their skin?
11. Is Commander Drew Feustel going to try to beat his third-place record for
cumulative time spacewalking during this mission?
12. What sensors are used to collect data and determine the amount of Cosmic
rays aboard the ISS? And who monitors that data over time?
13. How do you draw blood in space for all the experiments requiring that? Do
you have to use a special type of syringe?
14. Is your daily routine regimented to a time zone, or can you sleep, wake,
and work at times you choose?
15. How long did it take to make CIMON and get it approved for this mission,
and has anyone nicknamed it "HAL" yet?
16. Do ambient noises sound different in the Bigelow Expandable Activity
Module (BEAM) compared with the other sections of the ISS, and can you
please record ambient sounds inside the Bigelow Expandable Activity
Module (BEAM) for us?
17. What happens if you take apart a jumbled Rubik's cube and reassemble it
correctly in front of CIMON? Will it detect that as cheating and call
you out on it?
18. Would Infrared lights help the High Definition Earth Viewing (HDEV)
cameras to see Earth when the ISS is looking at the night sides?
19. Have you watched the new episodes of BattleBots on Discovery Channel? Our
school S.T.E.A.M. Director JediJill, and I, and Ethan, and Cayden, and
Sara from Team Kraken-BattleBots are all here today. Our robot's primary
weapon is a pneumatic crusher. What kind of pneumatics are used on board
the ISS or the Soyuz?

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), the Center for the Advancement of Science in
Space (CASIS) and 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 informa
tion, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,

Subject: [amsat-bb] Trying to understand downlink corrections
Message-ID: <1440710733.2179672.1531243682690@????.?????.???>

Greetings,
I have been using a SDR dongle to receive the downlinks of SSB satellites.
The combination of SatPC32's Downlink Correction feature and the SDR's
visual display helps to zero beat the CW beacon exceptionally well.? The
Lat/Lon is good to 6 decimals.? However, I find that the downlink correction
needed is quite different for different satellites. Could it be due to
rounding off errors or due to temperature variations at the satellite itself
??? Maybe this has been explained earlier, but I wonder why ??
?
Obviously, the more I learn, shows how less I know...? Thanks for any
pointers !?
