November
18 Marked 2nd Anniversary On Orbit for AMSAT-OSCAR 91
Happy 2nd
Anniversary, AMSAT-OSCAR 91! At 09:47:36 UTC on Novem-
ber 18, 2017, RadFxSat
(Fox-1B) launched on a Delta II rocket
from SLC-2W at Vandenberg Air Force
Base and became AMSAT-OSCAR 91.
RadFxSat (Fox-1B), a 1U CubeSat, is a
joint mission of AMSAT and
the Institute for Space and Defense Electronics at
Vanderbilt Uni-
versity. The Vanderbilt package is intended to measure the
effects
of radiation on electronic components, including demonstration
of
an on-orbit platform for space qualification of components as well
as
to validate and improve computer models for predicting radiation
tolerance of
semiconductors.
AMSAT constructed the remainder of the satellite
including the space
frame, on-board computer and power system. The amateur
radio package
is similar to that currently on orbit on AO-85.
RadFxSat
(Fox-1B) was sent aloft as a secondary payload on the Unit-
ed Launch
Alliance (ULA) Delta II rocket with the Joint Polar Satel-
lite System
(JPSS)-1 satellite. RadFxSat (Fox-1B) is one of five
CubeSats making up this
NASA Educational Launch of Nanosatellites
(ELaNa) XIV mission, riding as
secondary payloads aboard the JPSS-1
mission.
Uplink: 435.250 MHz FM
(67.0 Hz CTCSS)
Downlink: 145.960 MHz FM
Satellite health and
experiment telemetry are downlinked via the
Data-Under-Voice (DUV) subaudible
telemetry stream, which can be de-
coded using the FoxTelem
software.

November
21 Marked 6th Anniverary of AMSAT-UK's AO-73 FUNcube-1
This week AMSAT-UK
and the FUNcube team recalled the events on launch
day. A very short time
after the launch from Yasny in Russia and with-
in a few minutes from
deployment, the very first frame of data from
the low power transmitter on
board, was detected and decoded by ZS1LS
in South Africa. He was able to
relay the data over the internet from
his Dashboard to the Data Warehouse and
the numbers, appeared, as if
by magic, at the launch party being held at the
RSGB National Radio
Centre at Bletchley Park.
After a very brief check
out, the FUNcube team were able to switch
the transmitter to full power,
again at the very first attempt, and
were quite amazed at the strength of the
signal from the 300mW trans-
mitter on 145.935 MHz. The transponder was then
switched on and suc-
cessfully tested.
The team finished the day with
a request to AMSAT-NA for an Oscar
number and were delighted to receive the
AO73 Oscar 73 designation!
Since then, FUNcube-1, with a launch mass of
less than 1kg, has oper-
ated continuously with only a very few
interruptions. In excess of
32000 orbits, 750 million miles travelled, and
with more than 7 mil-
lion data packets downloaded and stored in the Data
Warehouse.
The spacecraft is presently in continuous sunlight and to
convert as
much of the sun’s thermal energy into RF (to help keep it cool),
it
remains in continuous high power telemetry mode. We anticipate
this
situation will continue until early May next after which the
team
expect to have 3 months with some eclipse periods.
Of course,
EO88 – Nayif 1 continues to operate autonomously with the
transponder active
when in eclipse and JO99 – JY1Sat, which includes
image downloads, and which
was launched just under a year ago, also
remain active on a 24/7
basis.
The FUNcube team still receive many requests for Fitter message
up-
loads for school events…please contact us by email to
operations@funcube.org.uk giving us
at least two weeks notice.
The FUNcube team continue to be very grateful
to all the many stations
around the world that continue to upload the
telemetry that they re-
ceive to our Data Warehouse. They really need this
data to provide
a continuous resource for educational outreach.
Dave
Johnson, G4DPZ, network administrator for the FUNcube Data Ware-
house
provided this update for users of the FUNcube Dashboard Soft-
ware, "The
server addresses warehouse.funcube.org.uk and

Proposed
FCC Auction of C-Band Increases Competition for Allocations
In an IARU
News Release by Dave Sumner, K1ZZ and posted by Rick Lind-
quist, WW1ME on
November 18 via the ARRL-IARU@groups.arrl.org list
he
reports that the Plenary session to approve texts to be included in
the
Final Acts was scheduled to end at noon Thursday, November 21 and
delegates
at WRC-19 faced a daunting workload as the conferees try to
reach consensus
on several remaining issues including the agenda for
the next
WRC.
Small Satellites which are increasingly commercial have been
granted
access to the space operations bands at 137/149MHz away from
amateur
allocations.
The amateur secondary allocation at 5725-5850
MHz, which includes an
amateur-satellite C-band downlink at 5830-5850 MHz, is
the subject of
an unresolved conflict over parameters for wireless access
systems
including radio local area networks. 5 GHz Wi-Fi will see most
expan-
sion below amateur radio in the 5150-5250 band reducing it impact
on
our 5725-5850 range.
An article published by CNBC, also on November
18, a news item by
Michael Sheetz, "Satellite stock Intelsat drops 40% after
FCC 5G dec-
ision", discusses increasing pressure in the United States due to
a
proposed public auction of 280 megahertz of the C-band spectrum.
This
article can be accessed in entirety at:
https://tinyurl.com/ANS-328-CNBC-5G-Article
Sheetz
reports that FCC Chairman Ajit Pai said in a tweet that his
agency “must free
up significant spectrum” for 5G telecommunications.
The FCC said it expects
to begin a public auction of C-band to happen
before the end of 2020, a blow
to satellite operators using the valu-
able spectrum.
The FCC
Chairman's tweet on the subject can be accessed at:
https://twitter.com/AjitPaiFCC/status/1196468857025835009
Four
commercial satellite operators, including Intelsat, provide
C-band services
in the U.S. to about 120 million households. The FCC
wants to repurpose the
C-band spectrum for 5G and an auction is ex-
pected to raise tens of billions
of dollars. But a public auction
would see the proceeds go to the government.
The commercial C-band
satellite operators have organized as the 'C-Band
Alliance' to oppose
a public auction of these frequencies. The C-Band
Alliance has been
pushing for a private auction. The group has given a
proposal to the
FCC where the satellite operators would keep some of the
proceeds
while paying taxes on the sale, as well as contributing at
least
$8 billion to the U.S. Treasury and possible helping fund a rural
5G
network.

called the 'APRS to
Discord bridge'. The Discord network supports
text and voice chat, project
documentation and source code for dev-

information about the Discord network see https://discordapp.com/
The APRS to
Discord bridge, by Alexandre Rouma (@WhatsTheGeekYT on

to connect APRS traffic from terrestrial and
spacecraft sources with user's
servers on the Discord network. The
software, still under development, is
pretty simple at the moment
but will be open source (Node.js). The design
will allow amateur radio
groups to set up their own node for bridging an APRS
callsign/message
to their discord server. It is written in a way that
requires the bot
operator to validate amateur operators with a special role
in Discord
preventing illicit use by non-licensed operators.

The
Voyage Home: Japan's Hayabusa-2 Probe Heads Back to Earth
By Kyoko Hasegawa -
Tokyo
Japan's Hayabusa-2 mission to the asteroid Ryugu received its
orders
to head for home on Wednesday, November 13. Next, on November 18
it
broke free of the asteroid's gravity. It will fire its main
engines
early next month en route to Earth, JAXA said.
Hayabusa-2 is
carrying samples that could shed light on the origins
of the Solar System. It
took the probe three-and-a-half years to get
to the asteroid but the return
journey should be significantly short-
er because Earth and Ryugu will be
much closer due to their current
positions.
Ryugu's orbit ranges from
.96 AU to 1.41 AU with a period of 474 days,
coming within just 95,400 km of
Earth at its closest (just 1/4 LD),
but is currently 1.7 AU away. Hayabusa
will spend the next year clos-
ing that distance to Earth and will eject its
sample capsule into the
atmosphere in December 2020. After the departure burn
Hayabusa-2 had
changed it's orbit to a 0.96 x 1.41 AU x 5.9 deg heliocentric
orbit.
Hayabusa-2 is expected to drop the samples off in the South
Austral-
ian desert. Under the current plan, Hayabusa-2 will boldly
continue
its journey in space after dropping off its capsule to Earth,
and
might "carry out another asteroid exploration," according to
JAXA.
