To all IARU QSL’s Bureau:
We are experimenting problems with the postal service due to local customs bureaucracy.
This result, in some cases, in the return of the sent parcels as “unclaimed”.
To solve this issue, please consider the following suggestions:
1- The parcels should weight less than 2 kg (4.41 lb)
2- Attach a customs declaration with the legend “QSL used cards, no commercial value”
3- If available, send an email with the tracking number to bureau@lu4aa.org

AO-91 Commissioned – Declared Open for Amateur Use!
At 06:50 UTC November 23, 2017 @AMSAT Engineering officially
commissioned AO-91 (RadFxSat/Fox-1B) Satellite. AMSAT VP of
Engineering, Jery Buxton N0JY turned over operation to Mark Hammond
N8MH and AMSAT Operations in a QSO on the AO-91 repeater during the
pass over the Eastern U.S.
N8MH responded and declared AO-91 open for amateur use!

Fox-1B/AO-91 Facts
Name(s): AO-91 Fox-1B (RadFxSat)
NASA catalog number: TBD
Launch: Not Earlier Than 21 Sept 2017
NASA ElaNa XIV Mission
JPSS-1 Delta II, Vandenberg AFB, CA
Orbit: LEO (Low Earth Orbit)
Inclination: 97.6908 (Assuming it is Object 43016)
Eccentricity: 0259769 (Assuming it is Object 43016)
Period: Approx. 95 minutes
Estimated orbital lifetime: 5+ years
Size: 10 x 10 x 10 cm (4 inch cube)
Weight: 1.3 kg (~3 pounds)
Transmit power: 400 mW (Minimum)
Downlink: 145.960 MHz FM voice
AFSK digital data up to 9600 bps
Uplink: 435.250 MHz FM voice (67.0 Hz CTCSS tone)
From a communications standpoint Fox-1B has two major changes from
AO-85. First, it will fly with a more sophisticated power control
system which utilizes a Maximum Power Point Tracker to insure optimum
charging of the batteries under all illuminations. This will be
largely transparent to the typical user but will significantly
increase the available battery life. Second, the detection of the
67.0 Hz tone has been enhanced, which will also help accommodate
ground stations whose CTCSS tones may be slightly off frequency. The
combination will make accessing the satellite easier and also
decrease the likelihood of dropouts.
Doppler Shift Correction for Fox-1B
Correcting for Doppler shift will involve the same techniques as for
AO-85, with slightly
different frequencies to prevent mutual spacecraft interference:
Receive Frequency Transmit Frequency
(67.0 Hz Tone)
Satellite Position
145.960 MHz 435.240 MHz (Mem #1) AOS
145.960 MHz 435.245 MHz (Mem #2) Approaching
145.960 MHz 435.250 MHz (Mem #3) Passing
145.960 MHz 435.255 MHz (Mem #4) Departing
145.960 MHz 435.260 MHz (Mem #5) LOS
Note that the AFC on the receiver may be working hinting that making
the above adjustments may not be necessary. AMSAT VP of Engineering
Jerry Buxton N0JY states “… in ground testing with Fox-1A. We
could be +/- 10 kHz and not even know it (that’s how it was tested,
one guy programmed the wrong frequency in his HT).” He adds the
caveat,
“One station on the uplink is not the same situation as real life
though.”
Fox-1B Telemetry
Subaudible Telemetry
Except for a different downlink frequency, the low speed subaudible
telemetry will be the same as for AO-85. It will be supported by the
same FoxTelem software released for AO-85.
High Speed AFSK telemetry
There are no experiments on Fox-1B which will require the use of
high speed telemetry.

FUNcube-1 Celebrates 4th Anniversary
November 21st 2017, marked the fourth aniversary for FUNcube-1 in
orbit.
FUNcube-1 was launched at 07:10 UTC on November 21st 2013 and its
first signals were received immediately after deployment over the
Indian Ocean by amateurs in South Africa. Since then it has been
operating continuously in either its education mode or, with the
transponder active, in amateur mode when in eclipse and at weekends.
The spacecraft has spent the four years in space orbiting the earth
at between 640 and 580 km and has now travelled around the earth more
than 20,000 times. That represents a distance travelled of
approaching 500 million miles.
Up to now, each of the orbits has been spilt approximately 65% in
sunlight and 35% in eclipse. This has resulted in the temperatures
inside the small spacecraft varying by about 25o C during each orbit.
During the recent AMSAT Colloquium, Wouter, PA3WEG, during his
presentation about the FUNcube project mentioned that the power
available from the solar panels has been slowly increasing since
launch. This observation led the team to do some further
investigations as to the cause.
Although the launch was into a nominally Sun Synchronous orbit, over
time this has drifted and the spacecraft is now entering a period
when it will be in the sun for longer periods during each orbit.
The exact details are still being determined, but it seems likely
that, starting from January 2018, there will be periods when the
spacecraft will be in the sun for all, or almost all, of its orbits.
Of course, this means that the on-board temperatures will be much
higher than we have previously experienced in flight, although we
have some test records from pre-flight thermal air testing that were
undertaken after integration.
The key will be to discover what the equilibrium temperature will be
internally. For comparison, AO85 has already “enjoyed” periods of
full sun and its internal temperatures have reached up to around 55o
C.
So the next few months will be quite an exciting time for the team!
We remain extremely grateful to everyone is using the spacecraft for
both its educational and amateur missions. Of course we are also very
very grateful to those who are downloading the telemetry and
uploading the data to the Data Warehouse. It continues to provide a
unique record of “life on board” a 1U CubeSat in space.
FUNcube-1 / AO-73 details
TLM down link freq 145.935 MHz BPSK
Transponder:
Nominal Uplink 435.150 – 435.130 MHz LSB (Inverting) The passband
may be up to 15kHz higher depending on on-board temps. Low
temperature gives higher freqs!
Downlink 145.950 – 145.970 MHz USB
Please use a maximium uplink power of 5 watts to a 7 dBi gain
antenna. More power is not needed to use the transponder!
Currently operating full power TLM beacon (300 mW) when in sunlight,
and Transponder, plus low power (30mW) TLM beacon when in eclipse.
Normally switches to Transponder over weekends and holidays

EcAMSat Deployed From ISS – 1200 baud Telemetry & QSL Card for Reports
The E. coli AntiMicrobial Satellite (EcAMSat) mission will investigate
space microgravity effects on the antibiotic resistance of E. coli, a
bacterial pathogen responsible for urinary tract infection in humans
and animals. EcAMSat is being developed through a partnership between
NASA’s Ames Research Center and the Stanford University School of
Medicine. Dr. A.C. Matin is the Stanford University Principal
Investigator.
EcAMSAT was deployed from the ISS on November 20, 2017.
EcAMSat will investigate spaceflight effects on bacterial antibiotic
resistance and its genetic basis. Bacterial antibiotic resistance may
pose a danger to astronauts in microgravity, where the immune response
is weakened. Scientists believe that the results of this experiment
could help design effective countermeasures to protect astronauts’
health during long-duration human space missions.
Operating at 437.100 MHz FM, the EcAMSat beacon sends an AX.25 packet
every 5 seconds, similar to the format of the GeneSat-1, PharmaSat,
O/OREOS, and SporeSat beacons; the packet contains data about the
spacecraft systems operation.
A tracking screen, mission information, and mission status are dis-
played on the EcAMSat Mission Dashboard: http://ecamsat.engr.scu.edu/
Links to beacon decoding and packet uploading instructions are also
included on the Dashboard.

MAI-75 SSTV Over Moscow from ISS Planned for December 6-8
The MAI-75 folks have scheduled some SSTV activity during specific
periods
each day from Dec 6-8. The times correlate to a small number of
passes each
day in range of Moscow.
Dec 6, 2017
Setup and power on – 13:40-14:20 UTC
Power off – 17:05-17:15 UTC
Dec 7, 2017
Power on – 13:45-13:55 UTC
Power off – 17:30-17:40 UTC
Dec 8, 2017
Power on – 14:05-14:15 UTC
Power off and stow – 17:00-17:10 UTC
Yuri, UT1FG/MM, is back to sea on the Vessel Seahorse. It is
currently sailing from Algiers to Morocco where it will load cargo.
The plan is to sail to a USA port in the Gulf to be determined.
There are quite a few ships named Seahorse. The MMSI number is
538007572.
Yuri is using the Elk antenna but only has RG58 coax feeding it.
Even so he reports working K3SZH on AO-7 today. If he doesn’t find
coax in Morocco, perhaps we can get some coax to him when he arrives
in a USA port. So he is likely to do better on a Mode B satellite
rather than one with a UHF downlink. He has keps for AO-91, AO-85
and CAS-4B.
Please wait for a while before sending your logsheets. He will
likely be able to mail qsl’s when he docks in the USA.

Changes to AMSAT-NA TLE Distribution for 11-21-2017, Object Comment
Due to Thanksgiving being on Thursday, the AMSAT-NA TLE Distribution
for this week will be today, November 21, 2017. Next week we will
continue with the normal TLE distribution on each Thursday of the
week. Note that, per comments below, AO-91 is most likely object 43016.
It appears that AO-91 is in the group of cubesats launched on 11-18-
17 that include objects 43016, 43017, and 43018. The object 43015
that we were using for AO-91 has separated enough to be confirmed as
Buccaneer RRM by 18th Space Control Squadron at Vandenburg AFB, CA.
One of 18 SPCS many missions is launch analysis.
Therefore, based analysis (by Nico Janssen, (PA0DLO) and discussion
by Alan Biddle (WA4SCA), Jerry Buxton (N0JY), Nico Janssen (PA0DLO),
Paul Stoetzer (N8HM) and myself AO-91 is most likely object 43016.
Note that these objects are still very close together and one more
change could be needed. The process of identification is one of
waiting for a group of objects to separate enough to isolate the one
you are interested in and positively identify it’s signal as matching
a certain TLE set. Simple, right!
For comparison, Buccaneer (object 43015, not AO-91) is now at least
26 seconds from objects 43016, 43017, and 43018. Objects 43016,
43017, and 43018 are still about 2 seconds apart. (Analysis by
Nico,PA0DLO)

IARU Notes Progress Toward 50 MHz Region 1 Allocation
Significant progress was made in preparing for the World Radiocommunication Conference in 2019 (WRC-19) at a two-week meeting at the International Telecommunication Union (ITU) in Geneva in November 2017. However, there remains a lot to do before the reservations and concerns of regulators and spectrum users are adequately satisfied. The team representing IARU in Working Party (WP) 5A of the ITU Radiocommunication Sector (ITU-R) consisted of amateurs from Australia, Brazil, Canada, Germany, Ireland, Japan, Norway, the Netherlands, United Kingdom and the United States.
For IARU the main focus was on the WRC-19 agenda item which will consider a frequency allocation for the amateur service in Region 1 from 50 to 54 MHz similar to Regions 2 and 3. The current, mainly secondary, allocation 50-52 MHz in most European countries is a regional agreement. During the meeting input documents from IARU, France, the Russian Federation and Switzerland were considered with the following intermediate results:
l A rough consensus was achieved on the text which will provide the technical basis for discussions concerning the access to 50-54 MHz for the amateur service in Region 1.
l A method for calculating the spectrum needs of the amateur service in 50-54 MHz was proposed by IARU and has been accepted by some administrations. More information to justify the requested bandwidth however will be required.
l For sharing studies particularly in relation to the land mobile service and radiolocation applications in 50-54 MHz, a mutually agreed propagation model remains to be determined.
l No major objections to sharing with analogue television broadcasting in 50-54 MHz in Region 1 remain, provided that a time limited field strength limit is applied.
In addition to an amateur allocation in Region 1 at 50 MHz other key issues for the amateur service at WRC-19 include securing protection for amateur service primary allocations at 24 GHz and 47 GHz and minimising possible interference arising from Wireless Power Transmission for the charging of electric vehicles.
Following the meeting of Working Party 5A and other meetings related to the work of ITU-R Study Group 5 the ITU hosted the first of three planned Inter-Regional Workshops on WRC-19 Preparation. IARU Vice President Ole Garpestad, LA2RR, who also attended the WP 5A meeting, represented the IARU at the workshop to hear reports on progress by the regional telecommunications organizations.
