SSTV was sent from the same radio that has been used for previous events, a
D710E in the Zvezda (Service) module.

I enjoy Twitter. I am just very picky if who I follow. If they start saying
stupid stuff I quietly unfollow them. I have to say it is better than

Hi Jerry,
I would suggest that it's not who but what, in the sense of AMSAT vs. a
single AMSAT volunteer. My recommendation is to follow AMSAT (the
organization) tweets only. Even tweets from individuals that are of
satellite ops interest get retweeted by AMSAT, so it's a simple way to
get what you might be looking for without following a clutter of
tweeters. They even retweet me if I tweet something about Engineering
that is intelligent and useful information. There is an audience
looking for AMSAT information via Twitter, so I'm glad to share news on
their preferred platform. It would be foolish not to do so and somewhat
un-hamlike, given that we're building stuff that is/will be available
for satellite users worldwide. That's why I started using Twitter.
There are other worthy organizations, corporations, and government
agencies to follow too for your space (and other) interests that are
about news and information and not random nonsense. I follow various
NASA branches, and other space/satellite related stuff like Spaceflight,
SpaceX, Virgin Orbit to name a few, the
corporations/agencies/organizations that are AMSAT "job" related as well
as related space hobby interests. I follow only a handful individuals,
some who are AMSAT officers and a few friends/acquaintances who know how
to tweet useful or interesting info and then be quiet again, for a spell.
And let me add AMSAT-UK as a suggestion, they share in a way similar to
what AMSAT does here with useful info as it comes up.
Give Twitter a try, I'd say it's worth a look. You can ease in and add
more over time. I'd also suggest that you don't jump in and follow a
bunch right off because it might be information overload rather than
informative.
And if you don't like it you can blame me, in a Tweet! I'm a popular
"public figure" for that type of stuff.
Then just close your Twitter account, and move on...
Jerry Buxton, N?JY

For continuity of radio operations...
As another hurricane approaches the gulf coast with the potential to knock
out power to tens of thousands, I was pleased to see that CQ published my
article this month (Oct) on using an EV or plugin Hybrid for emergency power
for days or weeks. With the 10 to 100 kWh batteries in EV's and the 50kW or
so generators in hybrids, your car makes a great accessory for your house
when the grid goes down.
The article is just a short condensation of some of the Emergency Power
topic that is in the ARRL Energy Choices handbook I also posted greater
detail from the article on this page:

Throw in using a 3rd party client that kills the ads, stupid timeline
"featured tweets", and other nonsense they throw in the official client.
Tweetdeck on the web is way better than twitter.com is, even thought it is
owned by Twitter.

Steve -
Question about Yaesu controller rocker switches asked on July 8 and 9, 2020
by Bob Johnson, W7LRD and Ed Cole, KL7UW.
==
I researched this problem in 2014 after Yaesu USA Parts reported that no
replacement rocker switches (for repairs) were available. Since this was
after the Japanese 2011 T?hoku earthquake and tsunami, I assume the OEM
suppliers to Yaesu were lost.
This is a Photo of the LAST OEM switch, from Yaesu USA Parts (before 2011),
now discontinued. Photos at entry #8 (QRZ Q&A Tech Forums).
LOOK at photo carefully.
https://forums.qrz.com/index.php?threads/g-500a-replacement-switch.664784/
The Kenpro/Yaesu used an OFFSET Lever (Pivot) on that Rocker switch
mechanism.
The Paddle Lever is NOT Symmetrical about the pivot axis.
Kenpro designed their front panel molds (plastic injection) of the rotator
controllers to work with that specific Offset Lever style.
?
The old Japanese OEM switch used rivets (thru metal pin), while the NKK
levers use an outside edge plastic mobs to fit into holes on the variety of
paddle/rocker options.
There is not a thru pin on the NKK.
==
In 2014, I ordered the NNK Series M2 rocker switch parts (substitute
candidate) from Mouser, when Mouser stocked NKK # M202TYW01 . ($4.80 in
2014).
This part was correct size for Kenpro/Yaesu G500/G550 controllers and
accepts a variety of ?Paddle? styles
https://www.mouser.com/ProductDetail/633-M2022TYW01
This NKK rocker switch properly fits the Kenpro/Yaesu front panels (rotator
control).
https://www.mouser.com/datasheet/2/295/MrockersFlatFrame-1663268.pdf
HOWEVER, the standard NKK Levers (Paddles) are SYMMETRICAL.
They do NOT have the proper OFFSET.
NKK # AT4157C (Red)
https://www.mouser.com/ProductDetail/633-AT4157C
NKK # AT4157A (Black)
https://www.mouser.com/ProductDetail/633-AT4157A
NKK Switch Accessories
https://www.mouser.com/datasheet/2/295/accessorieshardware-10910.pdf
===
SOLUTION ??
Someone (AMSAT member?) to design a proper ?Offset? Paddle (asymmetrical)
for the standard Rocker switch mechanisms (NKK, C&K) that fit Kenpro/Yaesu
rotator controllers.
The Design (CAD) could then be 3D-Printed OR Injected Molded (Plastic).

Just got the following from Halvard, LA7XK:
We arrived this afternoon. I got my antenna and radio set up earlier
this
evening and worked 2 EU contacts and 2 in Asiatic Russia, SSB and CW
to test the radio. All OK. We then had to go to get some dinner and now
I am set up for the 1929 pass, EU and maybe JA this pass, I will
try to stay up as long as possible before I drive down to the hotel
to get some sleep. My priority will be NA and JA.
the 2100 utc and the2300 utc passes should be OK for east NA.
I will work SSB tonight around 435660 downlink.

Hi folks, but mostly the ARISS team,
First, thank you for hosting the extended SSTV event on the ISS. It was
long enough that I was able to coach a few folks who had problems one
day, have a success the next. Also thank you for including English
subtitles to the predominantly Russian images, and Spanish for the one I
saw regarding Equador's nanosat.
But a request... Is there a better font which could be used for future
events? I noted several folks here who were able to grab an image, but
couldn't read any of it, not even the part in their own native
language. A sans-serif font would be a good starter, perhaps one with
skinnier lines (less bold) would help too. Any text at this resolution
is hard, and I'd rather pick a more friendly font than try to increase
the size for readability. Pictures are more pleasing than text.
To the general population, is there a "best" font that can be
recommended for the text used for Latin-based languages at this
resolution, and with this sort of "propagation"?

If I recall, one of the big reasons computers used san-serif fonts is
because they have a simpler construction and read better at low resolution.
Serif is easier for humans to read large blocks of text like a book, but
requires a higher resolution to be effective.
Also, I've heard some people reporting that the images were just a little
less sharp than previous events like this. I haven't compared myself. I
believe there is a new radio onboard. Is there a possibility that the audio
path from the computer to the RF modulator is being bandwidth-limited
somehow preventing the higher frequency edge transitions in the image from
retaining their sharpness?

Greg,I appreciate you taking time to not only mention the resolution issue,
but also share some possible solutions. I've also noticed this particular
issue since most of my demods are done on my smartphone. I believe many of
our ARISS team view the amsat-bb and will see your remarks, but regardless,
I'll be sure to pass them along directly to our team.Thank you and everyone
who participate in our ARISS SSTV events.

ARISS Contact Applications (United States) (***)
?
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 anticipates that the contact would be
held between July 1, 2021 and December 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 deadline to submit a proposal is November 24th, 2020. Proposal
information and more details such as expectations, proposal guidelines and
the proposal form can be found at www.ariss.org. An ARISS Introductory
Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite
link to sign up is: https://ariss-proposal-webinar-fall-2020.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.
?
Please direct any questions to?ariss.us.education@?????.???.
?
For future proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of Information
Webinars, go to www.ariss.org.
?
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.

Hi Jerry,
I would suggest that it's not who but what, in the sense of AMSAT vs. a
single AMSAT volunteer.? My recommendation is to follow AMSAT (the
organization) tweets only.? Even tweets from individuals that are of
satellite ops interest get retweeted by AMSAT, so it's a simple way to
get what you might be looking for without following a clutter of
tweeters.? They even retweet me if I tweet something about Engineering
that is intelligent and useful information.? There is an audience
looking for AMSAT information via Twitter, so I'm glad to share news on
their preferred platform.? It would be foolish not to do so and somewhat
un-hamlike, given that we're building stuff that is/will be available
for satellite users worldwide.? That's why I started using Twitter.
There are other worthy organizations, corporations, and government
agencies to follow too for your space (and other) interests that are
about news and information and not random nonsense.? I follow various
NASA branches, and other space/satellite related stuff like Spaceflight,
SpaceX, Virgin Orbit to name a few, the
corporations/agencies/organizations that are AMSAT "job" related as well
as related space hobby interests.? I follow only a handful individuals,
some who are AMSAT officers and a few friends/acquaintances who know how
to tweet useful or interesting info and then be quiet again, for a spell.
And let me add AMSAT-UK as a suggestion, they share in a way similar to
what AMSAT does here with useful info as it comes up.
Give Twitter a try, I'd say it's worth a look.? You can ease in and add
more over time.? I'd also suggest that you don't jump in and follow a
bunch right off because it might be information overload rather than
informative.
And if you don't like it you can blame me, in a Tweet!? I'm a popular
"public figure" for that type of stuff.
Then just close your Twitter account, and move on...
Jerry Buxton, N?JY
