The basic operating plan is described
here:??https://www.amsat.org/satellite-schedules/. Normally, the satellite
is switched to L/V mode on Saturday evening (early Sunday UTC), and remains
in that mode for 24 hours. A successful change to L/V mode is announced on
the AMSAT-NT Twitter feed:??https://twitter.com/@?????.?
You can check the status of the satellite at the telemetry dashboard
page:??https://www.amsat.org/tlm/health.php?id=4&port=.?If the "LBand Uplink
Enabled" parameter is TRUE, it's in L/V mode. If FALSE, it's in U/V mode.?

The map centers on the observer only with the zoom 1 maps (control Z =
Z1) and the right setting in menu "Optiions". With Z2 the map will
always center on the satellite to keep the foot print in the visible
part of the window.

Hi All,
Just to confirm that AO73 is now in safe mode (low power beacon only, no
transponder). We have set this mode as the satellite is about to enter a
period of continuous sunlight (for about 9 months). There is more
information at https://funcube.org.uk/news/
The plan is to change to education mode (high power beacon) next Friday.

Mark KK6OTJ and I tried this latest pass. No dice. Got back a couple of
struggling packets, like NO-84 on a bad day or NO-44 on a good one. No
digipeats for either of us. I might try one of the other two birds if a good
pass presents itself. But I don't think I'll try too many times before
calling it quits, especially with ISS, NO-84, and FS-3 all now operational
for digipeating.?

Hi Ryan!

Unfortunately even on very high passes with 50w & a directional tracking

I've tried the standard "ARISS" path as well as the various names & call

Has anyone been successful in digipeating (or making QSOs) on the BIRDS-2
satellites yet? I don't think I've seen any positive reports here on
QRZ.com, Twitter, or AMSAT-BB, although the BIRDS-2 team reported the
digipeater has been active since 8/23.
I'm going to try the 1832Z pass in a couple of hours. Maya-1 should be in
digipeating mode per the published Comm plan. Then will be on ISS at 1849Z.

Hi Bob,
you are running rotor control in flip mode. That mode is switched on by
choosing 180 degs for max. elevation. Azimut is then limited to 360 degs
(you can not combine flip mode and the 450-degs-option).
With flip mode enabled the program should work as follows: It checks
whether the az. rotor will get to it's end point (North) during the
pass. Therefore it checks at the beginning of a pass (exactly: if you
start tracking before the rotor has reached the end point) whether the
satellite will cross the meridian of your location in the North during
the pass. If so, it will steer the antenna in flip mode (az. antenna in
opposite direction, el. antenna 180 - true elevation). The color of the
control "R" will change to yellow). During such pass it should not
switch from flip mode to normal mode.
So, check whether your rotor control works in that way.

Tracking was correct but when the antenna was back down to about 45 degrees
the antenna swung around 180 degrees and "unflipped" the antenna, then
tracked properly to the opposite horizon. Since then it has been working
properly again, but I have not had another overhead pass.

Content-Type: text/plain; charset=utf-8; format=flowed
I'm slowly working towards building my own cross yagis for my home
setup. I started learning to use MMANA-GAL in order to model the
antennas and also looking for materials to build them. I found 8 mm
aluminium round tubing for the elements and 3/8" square tubing for the
boom. The cross boom is going to be 2" fiberglass, so I don't
necessarily have to choose for foremast installation.
I decided to settle on loop fed array yagis (LFA) because they are
directly fed with coax cable. First question: any reasons for not using
LFAs for cross yagis?
Second question: what is the sweet spot between number of elements, beam
width and boom length (for both 2m and 70cm antennas)? A lot of elements
means more gain, a narrower beam width, but also a longer boom and more
careful tracking. I haven't got any experience with working sats and I
wonder what is better: a couple of more dB gain, or a slightly wider
beam and a more compact antenna?
So far I modelled a 4-element and 5-element LFA for 2 meters. The
5-element has a 1 dB gain advantage over the 4-element one, a 3 dB
better F/B ratio, but is 2 meters in boom length, so that is quite
substantial. Any input appreciated. Cheers. --Hans (BX2ABT)

addition, the Nashua Area Radio Society will be holding an exposition for
young people, which will include a big satellite station. Please listen
for special event station N1T or club call N1FD during both days, and
possibly testing on Friday, and be nice if there are newbies trying for
their first contact!
In addition, the AMSAT forum will take place all Sunday morning and will
include demos of satellite contacts using a handheld and an HT. Please try
for QSOs with on FM satellites Sunday morning from Bob Hayes KB1SWZ (not
known if he will use a special event call sign).

DMR Station QRM's AO-92 Uplink
On August 27th, AMSAT Vice President-Operations Drew Glasbrenner,
KO4MA, noted:
"Recently there has been a DMR signal QRM'ing the AO-92 uplink on
435.350 or close by. Hotspots, repeaters, terrestrial simplex
(anything not satellite) should not be in 145.8-146.0 or 435-438 by
international bandplan. Please QSY these radios ASAP. Please share to
DMR, D-star, Fusion, P25 groups and similar, thank you!"
For amateur operators in the U.S., FCC Part 97 has a bit to say
about the way we should operate in the 145.8-146.0 and 435-438 MHz
amateur satellite subbands. Regulations in many other countries are
not as detailed as those established by the FCC on how we should
operate on different frequencies and bands. This includes where
hotspots and similar systems used for digital voice modes (i.e., DMR,
D-Star,
C4FM/Fusion) and other technologies like EchoLink and IRLP, should
operate.
Auxiliary stations are defined at 97.3(a)(7):
"An amateur station, other than in a message forwarding system, that
is transmitting communications point-to-point within a system of
cooperating amateur stations."
This definition includes "remote bases;" the nodes for systems like
EchoLink and IRLP; and hotspots used for digital-voice modes like D-
Star, DMR, and Fusion/C4FM (among others); as well as stations using
these hotspots and nodes. Auxiliary stations are not allowed in the
145.8-146.0 and 435-438 MHz satellite subbands per 97.201(b) - among
other subbands in the 2m and 70cm amateur bands.
Repeaters are defined at 97.3(a)(40) as:
"Repeater. An amateur station that simultaneously retransmits the
transmission of another amateur station on a different channel or
channels."
Since most hotspots are operating on a single frequency, they would
not qualify as a repeater. Even if the hotspot operates like a
repeater as defined above, repeaters are not permitted to use
145.5-146.0 MHz and 435-438 MHz per 97.205(b).
Beyond these two sections, Part 97 also has 97.101(a): "In all
respects not specifically covered by FCC Rules each amateur station
must be operated in accordance with good engineering and good amateur
practice."
Whether the hotspot is interfering with a satellite downlink in a
particular area, or it is interfering with the satellite uplink
affecting a much larger area, this would not be good amateur practice.
In addition to subbands where hotspots are not permitted, 97.101(b)
is also relevant:
"Each station licensee and each control operator must cooperate in
selecting transmitting channels and in making the most effective use
of the amateur service frequencies. No frequency will be assigned for
the exclusive use of any station."
Frequencies used by satellites are usually incapable of being
changed, and have been registered with a regulator like the FCC and
the ITU.
Hotspots are usually frequency-agile, and the frequencies used by
those systems can be changed to avoid potential interference to
satellites and other stations.
And all of this is in addition to local bandplans, which may already
have provisions for hotspots or simplex nodes.

AO73/FUNcube-1 Entering a Further Period of Full Sunlight
AO73/FUNcube-1 has been in space for almost five years and the
original Sun Synchronous Orbit has now changed slightly such that the
spacecraft will no longer be in eclipse for 35 mins every orbit.
The eclipse period has already reduced and will again become zero on
September 8, 2018. This means that our usual autonomous switching
between transponder on in eclipse and high-power telemetry when in
sunlight will no longer be effective!
This schedule was originally planned to provide a very strong
telemetry signal for schools to use during daylight hours and for
amateur operation at night (and also at weekends and over holidays).
We have already experienced a short period of full sunlight but this
time it looks like the spacecraft will be in this situation for more
than eight months until sometime in April next year.
In addition to the additional thermal effect that will occur during
this period, we also expect that the spin rate will increase. The
reason for this effect is not yet fully understood but may be related
to the amount of current flowing from the solar panels to the
spacecraft bus being sufficient to cause a torque effect with the
earth's magnetic field.
We have therefore decided to have AO73/FUNcube-1 initially operate
for alternate periods of one week in either safe or educational
modes. This should enable us to evaluate whether the currents do
affect the spin rate. Safe mode provides low power telemetry and
education mode the usual high power telemetry. It will also enable an
analysis to see whether the satellite becomes hotter or cooler in
each mode.
This will be a new experience for the spacecraft so the capture of
the largest possible amount of telemetry remains an important tool
for the team to have. We are very grateful to everyone who continues
to upload the telemetry they have received to the Data Warehouse. It
is invaluable.
In addition to AO73/FUNcube-1, the FUNcube-2 transponder on UKube-1
remains operational and EO88/Nayif-1 continues to operate
autonomously with the transponder on when in eclipse and high- power
telemetry in sunlight.
LAST MINUTE UPDATE: AO73 is now in safe mode (low power beacon
only, no transponder). We have set this mode as the satellite is
about to enter a period of continuous sunlight (for about 9 months).
There is more information at https://funcube.org.uk/news/
The plan is to change to education mode (high power beacon) next
Friday.

Interns Create Visualization of NASA Space-Ground Communications
For the first time ever, people worldwide can get an inside look
into what it takes to enable communications for nearly 40 NASA
missions, thanks to a small team of college students.
NASA's Near Earth Network (NEN) leverages more than 15 antennas
across the globe to provide a downlink for critical space and Earth
science data collected by the agency's satellites. A new web-based
app called NEN Now shows, in real time, simulations of the
complicated maneuvers these antennas undergo to link with passing
satellites, following them from horizon to horizon as the data
streams to the ground.
"NEN Now opens a window to the public, sharing live updates about
which of NASA's spacecraft are communicating with the Near Earth
Network," said Barbara Adde, director of policy and strategic
communications for the Space Communications and Navigation (SCaN)
program office at NASA Headquarters.
"Curious about what NASA is studying? You can click on a link and
find out what research that spacecraft is collecting data for and
sending down to Earth right at that moment."
Not only will NEN Now help the public understand space-to-ground
communications systems, but the tool will help technical and project
managers monitor the status of the network in detail, providing
information such as the actual position of the antennas' dishes.
At SCaN's request, Goddard modeled NEN Now after a similar app,
called DSN Now, built by NASA's Jet Propulsion Laboratory in
Pasadena, California, for the Deep Space Network (DSN). The DSN
provides communications services for missions in deep space and is
managed by JPL.
Ryan Turner, a ground system manager, had an idea to efficiently and
effectively develop the NEN app at Goddard by leveraging the skills
of college students and utilizing experienced engineers to provide
guidance.
"We started with three interns, who worked with the public
engagement team, NEN engineers and the GMSEC to lay out a prototype,"
Turner said.
GMSEC is the Goddard Mission Services Evolution Center, which
creates data system solutions across multiple projects and
disciplines. "It gave everyone a sense of what would be possible if
we created an operational version of the system."
Naje Fields was one of the first interns on the project in summer
2015. "Our biggest challenge for the prototype phase was to figure
out how to get the data from the real-time status server at [NASA's
Wallops Flight Facility in Virginia] to Goddard and into our app,"
she said. She and her partners, Kierra Harrison and Wallace
Phillips, used a number of networking and security techniques to make
it happen.
The prototype might have been ambitious for three college interns to
complete over the course of 10 weeks, but it was very well- received,
allowing Turner to establish a year-round program and to take on more
interns in the following summers.
Those groups have worked on multiple projects, including adding
commercial ground stations to NEN Now, implementing a NEN Now mobile
app, designing the Space Network (SN) Now for Goddard's other
communications network, and developing a 3D interface for NEN Now.
Both NEN Now and DSN Now have been incorporated into a larger app
called SCaN Now. An additional application for SCaN's third network,
the Space Network, is also being created by this intern team,
rounding out the real-time status display capability for all three
of SCaN's communications networks.
NEN Now is now available to the public at:

+ Petition to save WWV/WWVH
The National Institute of Standards and Technology (NIST) has
eliminated funding for the continued operation of time/frequency
standard stations WWV and WWVH in its Fiscal Year 2019 budget.
WWVB, on 60 kHz, which provides time data for so-called
"atomic clocks," would continue to be funded.
One petition started on the White House's "We the People"
petition site calls for restoration of funding for these two
radio stations. It needs at least 100,000 electronic
signatures by mid-September to generate a response from the White
House. The petition can be found at:
<https://petitions.whitehouse.gov/petition/maintain-funding-nist-
stations-wwv-wwvh>
(As of now, needs just over 90,000 more signatures by September 15)
