In the radio control window, you need to click the "L" button to link
the Tx and Rx frequencies, so that changing one moves the other a
corresponding amount. Also be sure the the satellite mode is correct,
i.e. set for a transponder not a beacon.

transmit CW if the receiver is in another mode. And second, I'm messing up
on the FM satellites sometimes because I'm forgetting to turn the PL tone
on. Can I leave it switched on when using another mode like SSB. Will it
only be present if FM is selected or will it appear in the audio when

The uplink and downlink frequencies can also be adjusted independently
by clicking on the triangles above and below each digit in the
display. That comes in handy for fine-tuning the radio if there's a
bit of drift or if both stations don't quite hear each other.

International Space Station Astronauts are Calling CQ ARISS Students (***)
??? ARISS-US program?s education proposal window open Oct. 1 - Nov. 30, 2018
?
September 25, 2018:? ARISS is seeking proposals beginning October 1, 2018
from US schools, museums, science centers and community youth organizations
(working individually or together) to host amateur radio contacts with an
orbiting crew member aboard the International Space Station (ISS) between
July 1 and December 30, 2019.
?
Each year, ARISS provides tens of thousands of students with learning
opportunities about space technologies, communications, and much more
through the exploration of Amateur Radio and space. ARISS has been pleased
of late, to be one of many possibilities of interest to educators during
NASA?s A Year of Education on Station, which celebrates an almost 12-month
presence of a teacher aboard the ISS.? The ARISS program connects students
to astronauts on the ISS through a partnership between NASA, the Radio
Amateur Satellite Corporation, the American Radio Relay League, other
Amateur Radio global organizations and the worldwide space agencies. The
program?s goal is to inspire students to pursue interests and careers in
science, technology, engineering, and mathematics (STEM) and in Amateur Radio.
?
Educators report regularly that student participation in the ARISS program
stimulates interest in STEM subjects and STEM careers. One educator wrote,
?Many of the middle school students who took part in and attended the ARISS
contact have selected science courses in high school as a result of that
contact.?? Educators are setting up ham radio clubs in schools and learning
centers because of students? interest.
?
ARISS is looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed, exciting
education plan. Students can learn about satellite communications, wireless
technology, science research conducted on the ISS, radio science, and other
STEM subjects. Students learn to use Amateur Radio to talk directly to an
astronaut and ask their STEM-related questions. ARISS will help educational
organizations locate Amateur Radio groups who can assist with equipment for
a once-in-a-lifetime opportunity for students.
?
The proposal window opens October 1, 2018 and the proposal deadline is
November 30, 2018.
For proposal guidelines and forms and more details, visit:
http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html
?
Proposal webinars for guidance and getting questions answered will be
offered October 11 and October 23, 2018, both at 8 pm Eastern Time. Advance
registration is necessary. To sign up, go to:
ariss-proposal-webinar-fall-2018.eventbrite.com/

Subject: [amsat-bb] Homebrew LFA yagi problems
Message-ID: <eb802a77-49e9-e3eb-9b19-ff027732e745@???.?????.???>
Content-Type: text/plain; charset=utf-8; format=flowed
I'm new to yagi building and so far have made a four element test LFA
yagi for 70 cm using a wooden boom and thick copper wire. Worked as
expected. I scaled it up and build a 10 element version very closely to
the specs of the InnovAntenna version (thanks KB1PVH for the help
there). You can find an photo here:
http://bx2abt.com/main/data/_uploaded/image/20180924-yagi.jpg The main
differences are the tubing (InnovAntenna uses 1/2", I use 8 mm) and the
width of the loop (InnovAntenna uses 46 mm, the smallest my tube bender
can do is 68 mm). Apart from these two the InnovAntenna has through-boom
elements and I use on-boom elements.
According to the lenght of my loop the resonant frequency is 436 MHz
(300/436 = 68.8 cm). Using a HT and my Daiwa SWR meter I only get
resonance (SWR 1:1) at 412 MHz. Making the loop shorter in length
doesn't make much difference. I understand that the reflector and
directors bring the high impedance of the loop down to the desired 50
ohms, hence they have a noticable influence on the resonant frequency.
How to go on from here? What am I doing wrong?
My first thought was to start trimming the elements up to 95% of their
current lengths (412/436*100 = 94.5%), then adjust the element spacing
to 95% of the original distance.
Second thought: there is (still) a feedline mismatch and the coax throws
off the resonant frequency. On the G0KSC website there is a design for a
1:1 symetrical coax balun and talk about the Pawsey stub. Worth trying?
I would appreciate input from people who have successfully homebrew LFA
yagis and who could point me in the right direction. Also if you have
experience with modelling LFAs using MMANA I would like to hear from
you. Cheers,
Hans

Hi
There has been some speculation on the -bb that this actually exists and is
not vapourware:
https://www.stellarstation.com/amateur
Yes, it does exist and I have one as an early adopter / beta tester and I am
preparing an article for OSCAR News.
Naomi Kurahara, the CEO of InfoStellar will be giving a presentation about
there philosophy for shared ground station operation for LEO satellites, at
the Colloquium.
https://rsgb.org/main/about-us/rsgb-convention/rsgb-convention-programme/
I do not wish to get into a SATNogs debate (I use it too) I simply want to
put this forward as an alternative and encourage you to watch the stream or
attend the event.

Fox-1Cliff Cubesat Ready for Launch
Jerry Buxton, N?JY, AMSAT Vice-President Engineering, delivered
and performed the integration of AMSAT's Fox-1Cliff CubeSat in
preparation for launch.
Unlike AO-85 and AO-91, AMSAT purchased a commercial launch for
Fox-1Cliff. Please consider a donation to help replenish the coffers
for GOLF and other future AMSAT projects!

https://www.amsat.org/product-category/amsat-presidents-club-donations/
Uplink: 435.300 MHz FM voice (67.0 Hz CTCSS tone)
1267.300 MHz FM voice (67.0 Hz CTCSS tone)
Downlink: 145.920 MHz FM voice; AFSK digital data up to 9600 bps
Transmit power: 600 mW nominal
Because only one uplink frequency can be active at a time, the use
of the Mode-L uplink will be limited to experimental periods announ-
ced in advance.
Fox-1Cliff carries the flight spare of the AO-85 Vanderbilt University
Low Energy Proton (LEP) radiation experiment, and the standard Fox-1
Penn State University?Erie gyroscope experiment. Virginia Tech pro-
vided a VGA camera which is the same as AO-92 but will provide images
at a higher 640 x 480 resolution. These non-SSTV images will be decoded
in the FoxTelem software.
Fox-1Cliff, unlike the other three Fox-1 FM spacecraft, does not have
an active AFC on the uplinks.
Fox-1Cliff's Subaudible Telemetry (low-speed telemetry) will be the
same as for AO-85, AO-91, and AO-92. It will be supported by the same
FoxTelem software already released.
As with AO-92, a high-speed mode will be used to support the Virginia
Tech VGA camera experiment. This mode will be active for 40 minutes
by ground command, reverting to standard U/v transponder voice operation.
Fox-1Cliff is named in honor of long-time AMSAT member, contributor,
and benefactor Cliff Buttschardt, K7RR (SK), who passed away in 2016.
Cliff?s contributions to AMSAT and other amateur satellite programs,
including serving as an adviser during the initial development of the
CubeSat specification at California Polytechnic State University,
earned him the Lifetime Achievement Award from Project OSCAR in 2006.

International Space Station Astronauts are Calling CQ Students
ARISS News Release No. 18-10
Dave Jordan, AA4KN, ARISS PR
International Space Station Astronauts are Calling CQ Students
ARISS-US program's education proposal window is open
Oct. 1 - Nov. 30, 2018
September 26, 2018: The Amateur Radio on the International Space
Station (ARISS) program is seeking proposals beginning October 1,
2018, from US schools, museums, science centers and community youth
organizations (working individually or together) to host radio
contacts with an orbiting crew member aboard the International
Space Station (ISS) between July 1 and December 31, 2019.
Each year, ARISS provides tens of thousands of students with
learning opportunities about space technologies, communications,
and much more through the exploration of Amateur Radio and space.
ARISS has been pleased of late, to be one of many possibilities
of interest to educators during NASA's A Year of Education on
Station, which celebrates an almost 12-month presence of a teacher
aboard the ISS. The ARISS program connects students to astronauts
on the ISS through a partnership between NASA, the Radio Amateur
Satellite Corporation, the American Radio Relay League, other
Amateur Radio global organizations and the worldwide space agencies.
The program's goal is to inspire students to pursue interests and
careers in science, technology, engineering, and mathematics (STEM)
and in Amateur Radio.
Educators report regularly that student participation in the ARISS
program stimulates interest in STEM subjects and STEM careers. One
educator wrote, "Many of the middle school students who took part
in and attended the ARISS contact have selected science courses
in high school as a result of that contact." Educators are set-
ting up ham radio clubs in schools and learning centers because of
students' interest.
ARISS is looking for organizations that will draw large numbers
of participants and integrate the contact into a well-developed,
exciting education plan. Students can learn about satellite com-
munications, wireless technology, science research conducted on
the ISS, radio science, and other STEM subjects. Students learn
to use Amateur Radio to talk directly to an astronaut and ask
their STEM-related questions. ARISS will help educational organi-
zations locate Amateur Radio groups who can assist with equipment
for a once-in-a-lifetime opportunity for students.
The proposal window opens October 1, 2018 and the proposal dead-
line is November 30, 2018. For proposal guidelines and forms and
more details, go to:
http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html
Proposal webinars for guidance and getting questions answered will
be offered October 11 and October 23, 2018, both at 8 pm Eastern
Time. Advance registration is necessary. To sign up, go to

ESEO Satellite Completes Vibration Tests - Final Testing to Begin
On September 28, 2018 the European Space Agency reported that the
European Student Earth Orbiter (ESEO), a student-built project is
about to enter its exciting final test phase, after having just
concluded the vibration tests, that demonstrated that the satellite
is able to withstand the harsh vibrations of launch.
ESEO is a 45kg micro-satellite mission to Low Earth Orbit developed,
integrated, and tested by European university students. The student
experiments on board ESEO include:
+ FUNcube-4 1260 MHz to 145 MHz amateur FM transponder together
with FUNcube compatible telemetry for educational outreach
+ Taking pictures of the Earth
+ Measuring radiation levels
+ Test technologies that can be used for future education
satellite missions.
ESEO reports several key milestones were attained by the student
teams to reach the final phase of testing:
+ August 28 - the assembly integration of the ESEO spacecraft was
declared complete. In this phase all the satellite?s physical
parts were assembled together, and all functional interconnections
were checked to confirm they work as required.
+ September 27 - ESEO reached another key milestone, when it
successfully completed the vibrations test campaign to demon-
strate that the design is solid enough to safely withstand the
launch.
In the next couple of weeks ESEO will undergo the thermal vacuum
and electromagnetic compatibility (EMC) tests to confirm that ESEO
is capable of coping with the thermal environment that it will
experience in orbit, and the electromagnetic conditions generated
during launch preparation, during the launch itself and in orbit.
FUNcube-4 is the amateur radio payload on the ESEO mission. This
payload will provide similar FUNcube telemetry to its predecessors
but will have a more powerful transmitter and thus be even easier
to hear. For amateurs, this payload will also provide a single
channel L/V transponder for FM.
Uplink: 1263.500 MHz FM voice with 67Hz CTCSS tone
Downlink: 145.895 MHz FM voice and telemetry
