When working with Eric on getting the Panadapter working for the 9700 one of
the beta testers noticed this bug. Go to the SatPC32 website and download
the latest version of 12.8d there, and you should get the CW switch back...

Subject: [amsat-bb] SatPC32 difficultly switching to CW
I am using SatPC32 on my 9700 with version 12.8d.
When I click on the CW- option on screen to switch to CW, the radio does not
change. Instead, the title of the window changes to 1524 1504.
I thought I saw mention of a patch after revision d but the website
indicates no patches.
I do have a CW entry in the DOPPLER.SQF file. This happened for different
satellites all with a CW entry.
Thanks

Assembly and Tuning Procedures for 2 meter ? 70 Cm
Dual band Circular Polarized Satellite Yagi
1. Unpack and separate all parts, UHF, VHF element rods, retaining nuts for
the element rods, T matches etc.
2. Assemble the two boom sections, be certain to match up the V half?s which
are on the ends of each boom section. Usually this is the only way they can
go together. Sections are marked VHF, UHF.
3. Mount the T matches this way: on the 2-meter end the feed point
connectors go towards the front of the antenna. On the UHF part, the forward
T match is mounted with the feedpoint connectors towards the front of the
antenna, the rear T match has its feed point connector towards the rear of
the antenna (see pics on our website)
4. Mount the element rods. The longest rod is the reflector, the Driven
Element is the ?" dia. The element rods mount in descending order of length
with the reflector being the longest, Install the nuts as you go. Just snug
them, do not apply a lot of torque as it is not necessary. Use wrenches if
necessary but just snug them only.
5. Slide the shorting bars onto the T match rods and driven elements. Set
the distances as follows for lowest SWR:
2 Meter part: 3 ?"
70CM part: All the way out (this is the setting for other brands of UHF
antennas as well)
The above distances are measured from the inside face of the shorting bars
to the end of the T matchbox, not the end of the black bushing.
6. Install the boom to mast plate just behind the last 2-meter element and
in front of the second 2-meter T match. Can hold the antenna at a 15 degree
angle (recommended if you do not have and elevation rotor). The V clamps V
parts butt against the mast.
7. Install the phasing cables. We recommend looking at the pictures on our
website to see how they install. Be certain to deep any cables away from
element rods, as that will detune the antennas. Never allow a cable to run
parallel to an element rod.

Thanks. That did it. I wonder if the author would consider adding a note to
his website that this bug was fixed too. I had downloaded it again but the
What?s New file didn?t mention this either so I did not assume it to be fixed.

> Has anyone tried copying the Ka-band transmissions (24 GHz, IIRC)?
That can only be active over UW footprint, so the number of stations
that could listen in is limited by that fact.? Too, unless they publish
some information on their planned operation times, there would be no way
to know what passes they may activate it.
HuskySat-1 is as Burns said, but perhaps more simply put, not an amateur
radio satellite.? It is licensed by FCC as Part 5 with a downlink in the
70cm amateur band.? Their operation of experiments, timing of such,
findings and dealings with the satellite, are all solely their desire
and their private information.? Please do not confuse the fact that it
has the AMSAT LTM as the COM1 radio system with that meaning that
HuskySat-1 is an amateur radio satellite.
HuskySat-1 will be an amateur radio satellite when UW is finished with
their commissioning, experiments, and data collecting, as they hand over
operation to AMSAT.? This should be coming in the next few months.? You
can help them with their science by copying telemetry and using FoxTelem
to decode and forward it to the AMSAT C.S. where they can have access to
Health Mode information from stations worldwide.? When they run Science
Mode, you can copy telemetry as well however that too will be limited to
activation over the UW footprint.? While FoxTelem will gather this
important science and send it to the C.S. it will not display the values
or results of any of the experiments included in the science as I
mentioned, those are private and operated under their Part 5 FCC license.
We can all help to get HuskySat-1 into Part 97 operation by doing the
following to help them as one of AMSAT's partners:
Copy as much telemetry as possible and be sure that FoxTelem is set to
send it to the C.S.
Watch the University of Washington Husky Satellite Lab website and
social media for news or announcements regarding operation of HuskySat-1
Accept the fact that their various use of science and resulting power
budget may result in variation of telemetry beacon operation and power
levels
Do not directly contact UWHSL with questions regarding their operation
nor the current status of the LTM beacon operation or power levels
Let them do their thing with their satellite and remember that when they
are finished, they are graciously giving the satellite operation to
AMSAT.? Please do not bite the hand that feeds you.
Discussion or questions regarding the LTM are fine, part of ham radio
with any satellite, station, or signal.? But, please remember that we
(AMSAT) can and will not directly answer any questions as to the current
operation or times of operation of the LTM telemetry beacon.? While we
are available, advising, and working with UWHSL as requested in order to
help them with any questions on the operation of LTM, we will not speak
for HuskySat-1 in any way unless and until they ask us or give us
permission.?
The video I did recently was entirely based upon information that I
received prior permisson from UWHSL for my use in the video.? Daily ups
and downs of telemetry signal and HuskySat-1 LTM operation are not
included in any way in that single permission nor do I expect to ask
them for further information or permission until we make the handover to
AMSAT.?
Let the kids commission, discover, test, operate, learn, and deal with
any of the number of Murphy possibilities that go with a satellite.?
Their project and the learning that goes with it are what this is
about.? AMSAT supports space-related education as you well know, and
providing an AMSAT radio such as LTM that can/will become an amateur
radio satellite as part of the satellite orbit lifetime is one aspect of
that outreach.? What the students learn about amateur radio as a
necessary adjunct to flying our radio is also a winning situation for
amateur radio in general, I think we all generally agree that once you
get your Tech ticket, it's kinda hard to shake off especially if you are
involved technical industry aspects such as the WUHSL students are.?
If they take a likin' to us because they see that we are simply
underpaid professionals and that we add value to their work, we may find
that there will be opportunities for future partnerships that bring
AMSAT other opportunities to "keep amateur radio in space" for a
fraction of the cost of building a Fox.? You can be certain that I think
and proceed with that in mind, underpaid or not.???
And of course, you are the we as well, as we all represent amateur
radio, the amateur radio satellite specialty of amateur radio, and along
with our members, AMSAT.?
I am inspired and excited about what these HSL kids are doing and I am
enjoying watching them go through the same ups and downs that I have,
that AMSAT Engineers have, with their first satellite.? They are not
quitters, they are quite determined and whether their individual chief
takeaways are landing a great job doing what they like or having
participated in making an amateur radio satellite it's worth the work we
put into our first LTM, right there.
Jerry Buxton, N?JY
Standard disclaimer - when I say kids I mean anyone of any age who enjoys
playing with amateur satellite stuff, a kid at heart.

Upcoming SpaceX CRS-20 Launch
The spouse of ARISS Hardware team member Ed Krome, K9EK, pointed out
that the ARISS next generation radio system, the InterOperable Radio
System (IORS) is prominently described as a primary payload, not
secondary, on the SpaceX CRS-20 mission which will be launched no
earlier than March 6, 2020 (ET).
The ARISS Team wants to express our heartfelt thanks to everyone that
has contributed to helping ARISS realize this major milestone
It should be noted that the ARISS hardware team is still very busy on
IORS development and final certification. While certified for launch
and stowage on ISS, the team is still in deep into the final
certification of the IORS for flight operations. Also, the build of
the second flight unit is in progress in Florida and in San Diego.
While CRS-20 represents the launch of SN 1001, the first flight unit,
it also represents the beginning of the "ARISS factory build" and
certification of all ten units.
The ARISS team also notes that November 13, 2020 will represent the
20th year of ARISS continuous amateur radio operation on ISS!

Georgia Institute of Technology GT-1 To Feature Amateur Radio Robot
Operation
The Glenn Lightsey Research Group, Space Systems Design Lab at the
Georgia Institute of Technology is sponsoring a 1U CubeSat mission.
The primary function of GT-1 is to be an educational proof of concept
and satellite bus demonstrator. It will use this mission as an
opportunity for undergraduates to get involved in all parts of a
space mission, from design to implementation and sustainment. It will
test a prototype deployable antenna and solar panels, which can be
used for future missions derived from the same baseline design, and
with inclusion of additional experimental equipment.
It will operate with AX.25 protocol to collect telemetry data. In
partnership with the W4AQL Georgia Tech Amateur Radio Club, the
satellite will also host a digital contact ROBOT payload, inspired by
the Russian ham satellites RS-12 and RS-13. It will collect QSO
information from individuals who contact the ROBOT as it orbits. The
satellite will also function as a standard digipeater. Proposing a
9k6 UHF downlink using G3RUH FSK modulation. Planning a JAXA

K7UAZ Radio Club Helps Prepare Satellite Radio Station for Space Camp
at Biosphere 2
In preparation for the upcoming Space Camp at Biosphere 2 , members
of the University of Arizona K7UAZ Amateur Radio Club are helping
with the placement of an Amateur Radio satellite ground station. The
first step was to mount the Yaesu G-5500 el-az rotor system to a
Rohn 45 tower. The complete station will include circularly polarized
M2 beam antennas for 2m and 70cm, an Icom IC-9700, computers and
tracking software.
Curt Laumann, K7ZOO, Station Manager for the K7UAZ club reports that
Space Camp management is enthusiastic about having UAZ students help
with the installation and setup of the station. Student involvement
will also include calibrating the rotator system, mapping the
artificial horizon for the tracking software and integration and
testing the tracking software with the radio.
Now in its third year, Space Camp at Biosphere 2 will be held
August 3-8, 2020. Space Camp at Biosphere 2 is a joint effort with
the University of Arizona Biosphere 2, the Arizona NASA Space Grant
Consortium, and the University of Kyoto, Japan. Students attending
the camp will experience college-level curriculum and activities
focusing on the biological/environmental facets of space travel.

New QO-100 Band Plan Announced
Just in time for the 1-year anniversary of the successful
commissioning of the two transponders of Qatar-OSCAR 100, an encore
is pending: The capacity of the NB transponder will be expanded from
about 250 KHz to almost 500 KHz.
In addition to extended areas for the various operating modes, more
space is also being created in particular for "mixed mode" and other
special operating cases. In addition to frequencies reserved for
emergency radio operations, more experiments are to be made possible
here.
But all this only with a maximum bandwidth of 2.7 kHz. Automatic
operation requires a special licence from the local licensing
authorities and must be coordinated with the operator beforehand;
this task is performed by AMSAT-DL on behalf of QARS and Es'hailSat.
To take account of user behavior, AMSAT-DL has almost doubled the
SSB range in particular.

Upcoming Satellite Operations
- Shorts
Mar 14-15 DN26/36 KC7JPC Linears (and possibly FM)
- Big Bend National Park (DL88) March 16-17, 2020
Ron AD0DX, Doug N6UA, and Josh W3ARD will operate from Big Bend
National Park to put grid DL88 on the air. Details will be added
here, as they come available, but you are more than welcome to keep
an eye on their individual Twitter feeds: https://twitter.com/ad0dx,
https://twitter.com/dtabor, and https://twitter.com/W3ARDstroke5
- #NevadaMayhem part 1: Central Nevada (DM19) March 21, 2020
David, AD7DB, will venture deep into Central Nevada to specifically
activate grid DM19 on Saturday March 21. This is actually down a
side road from "The Loneliest Road in America." Hardly any hams even
live in that grid. It's for sure that few ever activate it. On the
way there, Friday March 20, he will try to also activate some or all
of: DM06, DM16, DM07, DM08, DM17 and DM18. Going home Sunday,
March 22, he will try to visit them again. This will be on FM
satellites only. Internet and cell coverage may be very poor up there
but for updates check Twitter: https:/twitter.com/ad7db

Satellite Shorts from All Over
AMSAT SA Space Symposium Announced
* The AMSAT SA Space Symposium will be held on July 11, 2020.
Prospective authors are invited to propose papers by submitting a
brief synopsis to admin@???????.???.?? before Friday,
February 28, 2020. While the call for papers is ongoing till the end
of February, AMSAT SA is pleased to announce that Burns Fisher WB1FJ,
of AMSAT NA will delivery two papers at the symposium: Fox-in-a-box,
Fox telemetry reception using an inexpensive Raspberry Pi and a
J-pole antenna including a discussion on the optimal positioning for
a J-pole antenna for satellite reception and an overview of what is
in orbit currently and expected in the near future and their features.

* MEMESat-1 Proposed
Let's Go to Space, Inc.'s first satellite mission is the Mission for
Education and Multimedia Engagement, better known as MEMESat-1. This
spacecraft will be a 1U amateur radio CubeSat. It's primary mission
is to serve as an FM Repeater and to downlink donor submitted memes
via UHF SSTV protocol. MEMESat is also being created to engage people
through the sharing of memes from space and help fund small satellite
focused research.

* Two Commercial Satellites Link Up for First Time
A Northrop Grumman robotic servicing spacecraft has hooked up with an
aging Intelsat communications satellite more than 22,000 miles over
the Pacific Ocean, accomplishing the first link-up between two
commercial satellites in space, and the first docking with a
satellite that was never designed to receive a visitor.
Northrop Grumman's first commercial Mission Extension Vehicle, or
MEV 1, will take over propulsion responsibilities for Intelsat 901,
which is running low on fuel after more than 18 years in service
relaying data and television signals. MEV 1 is the first spacecraft
of its kind, and officials say the successful link-up with Intelsat
901 is a harbinger for a new era of commercial satellite servicing.
The automated docking early Tuesday also marked the first connection
of two satellites in geosynchronous orbit, a region high above the
equator where spacecraft move at speeds that match the rate of
Earth's rotation.

So nobody has heard it emit 24 GHz. Got it. That's all I was asking.
I wasn't asking either UW or AMSAT for privileged information, nor do I
expect any. My interest was purely technical curiosity, as one would
expect from a member of our hobby.
Much like any other (non-intelligence-organization) object in orbit, we
are not prohibited from listening to any RF emitted by the satellite,
even if we don't understand the content.

Zach,
What I said was not personal, it was an explanation and extension of
your question as to hearing 24 GHz.? I used your email as a reply to
subject to mention several things in general that I thought might not be
fully known since it is our first LTM and we're pretty used to talking
whole satellites here.?
All UW experiments must only be active over their ground station while
operating Part 5, and we have a timer built into the code in order to
switch out of Science Mode at or very near their LOS.? This is a scheme
that we started with Fox-1D, in which University of Iowa could command
their science mode/dump on and it would time out around their LOS.?
Unfortunately, their experiment had a partial failure and the use of
that feature never came to be.
I apologize for making it sound or seem personal.? I climbed on your
shoulders in order to shout general info at a crowd.? I will be more
cognizant of the appearance of any responses I write, especially in
public forums.
Jerry Buxton, N?JY
