Hi Dave. There is an issue with the old program WiSP running under WIN10. I
had no issues until I switched the sat computer here over from WIN7. For
various unknown reasons, Windows updates, shutting computer down without
closing WiSP first causes some kind of registry corruption. Only way I found
so far how to get it running again is to do a regedit, clearing out all WiSP
Falconsat-3 registry entries, and then re install the sats into WiSP. Just a
bit tedious. There has to be an easier way. Someone volunteered to
rewrite/recompile WiSP under a newer version of Windows but I understand
that the source code isn't available to do so.

And the third type, STRING inverter, which is the cheaper and much simpler
and has nothing but a single loop of DC wire on the roof. If there is any
noise, it is easy to suppress on the ground at the inverter with torroids
on just the two DC wires.
The String inverter is simpler and less costly. But it does require all
the panels in each array to point the same way. Minimum of about 10 and
maximum of about 14 panels per string.

General findings have beeen that panels with "mini-inverters" on the
panels themselves are very quiet. Panels with "optimizers" or DC-DC
converters on each panel and a main inverter on the side of the house are
very noisy! I specifically asked for the mini inverters and mine are
quiet, but I can hear
my neighbors system several hundred feet away with his "optimizers." You
can get a bag of ferrites and clamp them on every panel's output and it
will drastically quiet them down.

I have been running 5.8 Kw system using Kyocera panels and SMA inverters
now for 20 years. No noise at all. The inverters are less that 6 feet from
my radios.

Absolutely. Yours is perfect for simple DC sting inverter.
The optimizers are a disaster. RF WISE!
Also salesmen are Full of smoke and mirrors to convince people to pay more
for all kinds of ?benefits? of microinverters and optimizer, none of which
pertain to a clear roof with good sky.
The only thing you don?t get with a series string is fancy internet graphics
showing you the actual output of each and every single panel? But what
they don?t say about why you need that kind of detail is because their
optimizers and microinverters fail so much under the hot sun under the
panels, that they need this diagnostic every time they come back out to
?repair? their lousy system. it is extremely rare that the panel that
fails, because it is always the Optimizers or microinverters.
Most people WITH Microninverters for several years have reported they have
ALL had to be replaced over time. Because they Just cannot survive the
extremes under those panels. A string inverter sits in the basement or in
the shade near the ground and lasts forever?
And if a salesman tries to tell you that microinverters or optimizers are
better because a single cell shade in a string array will take out the whole
panel or array, they simply do not understand a series circuit with every 10
volt section of every panel bypassed with a diode! Even an optimizer or
microinverter is still connected to each panel, but each panel is still a
string of three 10v segments.
Each segment is bypassed by a bypass diode. So a shade on a cell takes out
ONE ten-volt section no matter what kind of system it is in. This is true
in a string array, in a microinverter panel and in an optimizer panel.
I am probably being too exaggerating, and probably they have better quality
microinverters, but they don?t really care about RFI because only one in
every 500 complains (hams)...

Bob, one person looking at my place quoted panels with optimizers going to a
string inverter. That does not seem to make sense since the roof these
panels would be on is totally unshaded and all facing the same direction.
So I wonder if you can get a string inverter without the optimizer, given
that my situation may be a bit unusual.
Thanks again for all the info! Looking forward to your book!

An International Space Station school contact has been planned with
participants at Faith Christian Academy, Orlando, FL on 14 Feb. The event is
scheduled to begin at approximately 14:30 UTC. The duration of the contact
is approximately 9 minutes and 30 seconds. The contact will be direct
between NA1SS and W9DWJ. The contact should be audible over Florida and
portions of the eastern U.S. Interested parties are invited to listen in on
the 145.80 MHz downlink. The contact is expected to be conducted in English.
Story:
Faith Christian Academy is a private school located in Orange County in
Orlando, FL. With a student body population of nearly 700, we teach grades
K-12. We offer an array of subjects and electives during and after school
hours. In addition to traditional athletic activities, we have an emphasis
in the arts and have intentionally developed our STEM program in recent
years. FCA leadership understands the diversity of the students that attend
and therefore strives to prepare them for any future endeavors that suit
their individual goals, personalities, and learning styles. Over 50 teachers
instruct our students to understand their purpose and to work toward it from
an early age. We believe in equipping children to become well rounded adults
that are educated, caring, and ambitious.
In preparation for the upcoming ARISS event, our school has done many things
to bolster excitement about the ISS and space exploration in general. The
students received credit for spotting and videoing the ISS as it passed
overhead at night. In addition, they filled out ISS activity books provided
on the NASA website, did Math projects on the distances between planets,
painted pictures of the themselves with galactic themes in Art, took field
trips to Kennedy Space Center, and were taught from curriculum that
emphasized the International Space Station and the anticipated mission to
Mars.
In the weeks to come, we will have a team from a nearby amateur radio Club
come to teach the students about Ham radio and Morse code. Also, FCA will
hold after school classes for students to create a Raspberry Pi device in
order to track the ISS and keep up with the current crew.
Participants will ask as many of the following questions as time allows:
1. What advice would you give new astronauts preparing to join the ISS?
2. What are the mental and physical effects of going from Earth to space and
back to Earth?
3. What is your favorite exercise to do in space and why?
4. Do all of you rotate jobs on the ISS?
5. How do you shave or cut your hair on the ISS without the hair floating
away?
6. Do you have a certain pre-flight ritual?
7. Can you see any constellations while on the ISS and do you have a favorite
one?
8. Have you ever experienced a major malfunction on the ISS?
9. Do your ears pop like they would when you fly in a plane?
10. Does everything in your body work the same in a microgravity environment,
for instance, does your heart work harder to pump blood through the body?
11. Are you recognized as an astronaut on the streets?
12. Are you allowed to request certain things to be delivered by the cargo
missions?
13. Describe the escape system on the ISS in case of an emergency.
14. What would you say has been your most important or meaningful experience
in space?
15. What is the temperature inside the ISS vs outside the ISS?
16. Is there wi-fi on the space station?
17. Where is the garbage stored on the ISS?
18. What experiment are you currently working on and is it going well?
19. Is there ever a time when you feel a sense of panic on the ISS?
20. What did you feel the first time you saw Earth from the ISS?
21. How long does it take for your body to feel "normal" once you are in
space?
22. What time zone do you work with on the ISS?
23. How many gallons of rocket fuel does it take to get to the International
Space Station?
24. How do you keep up with current events happening on Earth?

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,
