>From ARISS Vice Chair Oliver Amend DG6BCE: ESA Astronauts to offer
inspiration during isolation in????? #SpaceConnectsUs
?
https://www.esa.int/Newsroom/Astronauts_to_offer_inspiration_during_isolation_
in_SpaceConnectsU
In Europe and around the world, we?ve been getting used to a different way
of living in recent weeks. On Thursday, 26 March, ESA and long-time partner
Asteroid Day will host #SpaceConnectsUs ? a chance to connect across borders
and hear from space explorers, artists, and scientists about how to manage
ourselves and our environment as our communities battle a global pandemic.
#SpaceConnectsUs is an online event running on March 26th from 16:00?21:00
CET (15:00?20:00 GMT) on ESA WebTV and ESA YouTube to help everyone
practising social distancing or in isolation enjoy science, our home planet,
and our dreams of the sky above us.
The programme will feature remote connections with astronauts and guests
from all over the world.? The presenters and guests will speak to children,
young adults and their families and friends about their experience and
techniques in confined places, lessons in life from space exploration, their
trust in science and their sources of inspiration.? The programme runs in
five language segments starting at 16:00 in Dutch, followed by German (17:00
CET), Italian (18:00 CET), French (19:00 CET) and English (20:00 CET, 19:00
GMT).
?
Celestron, the telescope, microscope, and sports optics folks, now has
something called #STEMINYOURBACKYARD that you can find on Instagram,
Facebook, or Twitter.? By the way, I don't work for Celestron or have any
business dealings with them and this is just something I saw.? Apparently
there are 10 free STEM activities covering Astronomy, Nature and Wildlife,
and The Microscopic World.? Check out:

Amateur Radio on the International Space Station?
?
Contact Opportunity?
?
Call for Proposals?
?
Upcoming Proposal Window is February 1, 2020 to March 31, 2020
?
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS.? ARISS is happy to announce a proposal window
will open February 1, 2020 for contacts that would be held between January
1, 2021 and June 30, 2021. Crew scheduling and ISS orbits will determine the
exact contact dates. To maximize these radio contact opportunities, ARISS is
looking for organizations that will draw large numbers of participants and
integrate the contact into a well-developed education plan.?
?
The proposal window for contacts between January 1, 2021 and June 30, 2021
will open on February 1, 2020 and close on March 31, 2020.? Proposal
information and documents can be found at www.ariss.org. Two ARISS
Introductory Webinar sessions will be held on November 7, 2019. The first is
at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be
covered during both sessions, so choose the session that best fits your
schedule. The Eventbrite link to sign up
is?https://ariss-introductory-webinar-fall-2019.eventbrite.com?.
?
The Opportunity?
?
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.?
?
An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight
and the complexity of scheduling activities aboard the ISS, organizations
must demonstrate flexibility to accommodate changes in dates and times of
the radio contact.?
?
Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations' volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students around the world using
Amateur Radio.??

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 ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

>>> W4GCW says he does not listen on the ISS frequency
Were you perhaps transmitting on 144.390 at some point & that's why he's
shown as the iGate on the screen capture I posted?
https://www.qsl.net/k/k4kdr//images/KO4AQF-digipeats.png
... that would explain it, so very sorry for any confusion that I might
have caused.
On a related note, for anyone running an iGate with Direwolf, the directive
"SATGATE 15" can be helpful by putting a 15 second delay on your upload of
heard packets. That way, if you happen to hear something from a neighbor
directly (but his packet IS digipeated via satellite), some other iGate
will likely hear the digipeat from space and upload that before your iGate
gets around to uploading the locally heard packet. The end result is that
your locally-heard packet is discarded as a duplicate and what shows on the
APRS network is the digipeated packet -- a much better outcome!

It?s all good. I have found this discussion very enlightening in how the
APRS network actually works. Back to my original problem, I am guessing
that when the ISS is passing over that if it does receive my packets then
there may not be an iGate nearby that can digipeat it back to the larger
APRS network. As to whether I accidentally transmitted on the normal APRS
frequency, I can?t rule that out and it may have happened on accident
because in my radio that memory is next to the ISS APRS memory. Therefore
an accidental slip of the finger while holding the radio would accidentally
turn the knob and adjust the memory.

Message-ID: <00c501d603d1$590200c0$0b060240$@???.???>
Content-Type: text/plain; charset="us-ascii"
Over the last year I have evolved to a completely new AZ/EL rotor control
setup, an AlphaSpid AZ/EL rotor system, a Green Heron R-21 controller,
controlled by SatPC32 and PStRotortator. In the last few weeks my neighbors
have mentioned that my rotor is "beeping'. As it is just 15 feet from their
lunai that they sit in at night I'm a little concerned that their comments
are going to get more unfriendly. As I have recently lost a good part of my
high frequency hearing I can't hear the tone. I have had to stop collecting
Telemetry at night to try to alleviate the situation. Does anyone have a
clue on why the rotor system would beep? Does anyone have a clue on how to
stop this from happening? My only input on this as I can't hear the beep,
but I'm now feeding more voltage to the rotor system then before when I was
using the stock controller supplied by AlphaSpid. The higher voltage allows
the rotor to turn at a much improved rate. If I knew I was going to have to
put up with all this BS I would of just bought another 5500 at half the
price.

I do not own one but looking at the documentation for the controller I
noticed this,
"gradual startup and shutdown of rotor power to reduce stress on towers,
antennas and rotors. This is achieved by pulse-width-modulating the
operating voltage for the rotor."
That could very well be the source of the "beeping"? with the windings
in the motor singing.

All,Has anyone else had the problem of not hearing your own downlink when
working SO-50?? In the past I was able to hear myself, but lately I cannot
not.? I don't know if I change some setting or that the Icom is going bad.
Thanks for any help.? I appreciate it in advance.

Jim,
With SO-50, especially, this is very common. The 2m uplink has a harmonic
very close to the downlink, which if not filtered out, can wipe out your
local downlink whenever you are transmitting. I'm not familiar with the
910 enough to know how well it does at this, though.
You were getting in fine this morning, though (not sure if you copied my
QSL)!

The 910 is generally very effective at filtering out harmonics from
the transmitter. However, harmonics can be generated beyond the
transmitter by poor connections, bad feedlines, or a damaged antenna.
Check your entire antenna system to make sure there are not any
problems.
