Hi,
The server addresses warehouse.funcube.org.uk and data.funcube.org.uk are no
longer operational.
If you have FUNcube Dashboard(s) using the URL data.funcube.org.uk, please
change it to data.amsat-uk.org as forwarding will no longer
take place.
All data from data.funcube.org.uk was transferred to the new server some
time ago.

I gave up on trying to get the 9100 to work except for the KD2C PAT board.
I'm trying to get a signal from an SDRPlay RSP2 that is connected to the
9100 via the PAT V 9100. Not getting any decodes yet, messing with the VAC
levels between HDSDR and Fox Telem. Anyone have this setup working? Yes the
WX is bad here and I have nothing better to do :-)

Hi Mark and Jeff,
In the past I would have agreed that something was being filtered out.
Having recently taken some spectrum pics of DUV I'm not so sure,
https://www.dropbox.com/s/ghuo0jtg527b20s/duv.jpg?dl=0
The upper pic is the Data2 output the lower pic is USB to my eye they
both look the same.
USB mode with foxtelem tries to work, you see a eye try to form, but
even using Data2 for an input I rarely see the SNR exceed 5, of course
the soundcard you are using can make a big difference also.
So I dunno

I have very sad news. My good friend, Brian Kantor, WB6CYT
<https://photos.smugmug.com/photos/i-qRxpLrc/1/X4/i-qRxpLrc-X4.jpg>,
suddenly passed away this week at his home in San Diego, California.
Brian retired only two years ago after 47 years of service on the staff
at the University of California San Diego (UCSD). Way back in the mid
1980s, Brian and I founded AMPRnet, the TCP/IP over amateur radio
network. He continued to manage it until his passing.
Brian recently created and served as chair and CEO of Amateur Radio
Digital Communications (ARDC), a charitable foundation funded by the
sale of unused AMPRnet IPv4 addresses.? ARDC promotes STEM education and
amateur radio digital development through scholarships and by funding
the development of open source hardware and software.
Brian will be sorely missed and impossible to replace. Memorial
arrangements will be announced when known.

Is anybody on this list a power (or even casual) user of nec2? I've been
tinkering with xnec2c, and am attempting to model AA4TX's parasitic lindy
antenna (70cm) as a check (Tony provided gain plots in his paper).
However when I plot gain, all I get is the standard donut pattern (vert
polarization), and sort of modified donut when viewing RHCP.
.nec file is below (apologies for formatting). Thanks in advance to
anybody that can offer insight. The learning curve for this software is
steep. (not sure if Steve Conklin is on this list - but the below nec data
was built off of his 2m satellite yagi model)

I forgot!!!
You have to invert the angle of the parasitic elements to get RHCP. The
way you have model them is for LHCP.

Hello Roy,
I am a casual user of nec2 but here what I have done:
1. Edit GM card by moving Z to 3
2. Edit GE card and select "Ground present, Structure reflection"
3. Edit RP card and decrease "points in theta" to 31. Also decrease
"increment theta" to 3
4. Add a GN card and select "Sommerfeld/Norton"
Hope this helps
Apostolos

Apostolos - thank you for your help. However, for these two suggestions,
can you provide the card position that the values go into
(I1/I2/F1/F2/F3/etc)? Both GM and RP cards seem to have multiple positions
that these could apply to (I am using the "nec2prt3.pdf" manual and the
descriptions are different than what you are using above). Thanks!

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@???????.???.?? 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
data.funcube.org.uk are no longer operational. If you have FUNcube
Dashboard(s) using the URL data.funcube.org.uk, please change it to

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@??????.????.??? 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.

Open Source 'APRS to Discord' Bridge Project Begins Testing
Harold Giddings, KR0SIV, reports on an on-going open source project
called the 'APRS to Discord bridge'. The Discord network supports
text and voice chat, project documentation and source code for dev-
elopers, gamers, and makers in an open source environment. For more
information about the Discord network see https://discordapp.com/
The APRS to Discord bridge, by Alexandre Rouma (@?????????????? on
twitter), is designed 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.

? KA9Q) of AMPRnet, the TCP/IP over amateur radio network. Brian
? continued to manage it until his passing. Brian recently creat-
? ed and served as chair and CEO of Amateur Radio Digital Commun-
? ications (ARDC), a charitable foundation funded by the sale of
? unused AMPRnet IPv4 addresses.? ARDC promotes STEM education and
? amateur radio digital development through scholarships and by
? funding the development of open source hardware and software.
? Brian will be sorely missed and impossible to replace. Memorial
? arrangements will be announced when known. via Phil Karn, KA9Q)
+ UniverseToday.com notes the contribution of Daniel Est?vez, EA4GPZ,
? with the location of the impact site of China's Longjiang-2 satel-
? lite on the moon: https://tinyurl.com/ANS-328-EA4GPZ-LunarImpact
? The article notes, "Among amateur astronomists and citizen scient-
? ists, Daniel Est?vez is a well-known figure. In addition to being
? an amateur radio operator with a PhD in Mathematics and a BSc in
? Computer Science, Est?vez is also an amateur spacecraft tracker."

+ Roland Hesmondhalg spoke on public radio station WFIT with FL Tech
? Professor Ken Ernandes, N2WWD, and two senior students Luiz Fernando
? Leal and Antonio Masturzo about the amateur radio project on the ISS.
? Did you know you can use amateur radio to talk to astronauts in space?
? Ken Ernandes is part of the team building the next upgraded communi-
? cation station to be flown on the ISS this coming year. The program
? is primarily intended by NASA to promote STEAM in schools. There is
? an application process to get a scheduled school contact and he
? would be happy to work with any body on the application process.

+ Scott Manley posted a video showing the effect if all satellites
? in orbit were visible. There are over ten thousand satellites in
? orbit, but only the largest ones in low earth orbit are visible
? in the hours just after sunset and before sunrise. What would the
? sky look like if you could see everything in space? He took satel-
? lite data and rendered a view of the night sky for an 'average'
? viewer in North America. View the satellites at:

+ Voyager's transmitters use just 23 watts, roughly the same as an
? incandescent refrigerator bulb, yet we are able to interpret the
? 0.1 billion-billionth of a Watt that makes it to earth from 11
? billion kilometers away. An article at wired.com explains:

+ AMSAT-LU (Argentina) plans to operate their WSPR buoy when it is
? deployed between November 25 through December 12, weather condi-
? tion permitting. The WSPR beacon will transmit on 14.095,6 MHz
? with 900 mW, callsign LU7AA. The beacon will be active for 2 min-
? utes ON followed with 8 minutes of standby. They appreciate WSPR
? reception reports to wsprnet.org which will qualify you for an
