Hello all,
I am looking for help on how to receive the BY70-2 with the M6SIG Linux
distro. I cannot get correctly the data transferred i the Proxy. I got the
gr-lilacsat with the command:
git clone https://github.com/bg2bhc/gr-lilacsat gr-lilacsat-master.
Set all how it says in the read me.md file but no luck.
I am noticing Thani see the signal in the FCDPP flowgraph ( I am using a
Funcube Dongle Pro Plus to RX ) but I do not get the constellation in the
BY70-2 demod flowgraph and in the meantime nothing in the Proxy window. I
have the same results also with good signals and with higher passes of the
satellite.
Please anybody can tell me where am I missing?
Anybody can help me to solve the problem?
Thanks in advance who will help me

Content-Type: text/plain; charset="UTF-8"
Hi All,
I've used SatPC32 with my Icom IC-910H successfully, I tried using SatPC32
with my Yaesu FT-817nd and ran into some problems tonight. I'm seeking
setup and troubleshooting help..
*a) Anomalous Behavior of FT-817nd*
Frequency does not change to satellite frequencies
Frequency stays on 7 MHz
On SatPC32 start up, mode on FT-817 changes from LSB to FM (in accordance
with AO-27)
Radio rapidly switches between VFOa and VFOb a couple times when I select
different satellites
Correct mode (CW/FM) seems to be chosen.
*b) FT-817nd notes*
Factory reset performed
CAT rate kept at 4800
Split mode is shown when SatPC32 is run
I've tried two different FT-817nd's and they both exhibit this anomalous
behavior.
*c) SatPC32 setup parameters worth mentioning*
version 12.8d - fresh installation
C+ i CAT control is ON
A- automatic satellite chane OFF
V- VFO mode OFF
..........<Radio Setup> parameters............
Radio 1 "Yaesu"
Model FT-817
Baudrate 4800 (verified same as menu item #14 "CAT RATE" on FT-817nd)
COM port - 7 (verified correct with Windows Device Manager. I plugged
and unplugged the CAT cable and could see COM7 appear and disappear with
the Windows Device Manager)
CAT delay 110
no boxes checked: RTS+12, DTS+12, KCT-Tuner, Auto Sat Rx/Tx change,
Satellite Mode
Radio 2 none
*d) Reading the manual*
I've read and followed the directions in the SatPC32 manual closely,
including the 'Hints for Yaesu radio" file.
*e) Communications to Yaesu verified with another program*
I verified the computer and CAT cable can communicate with the FT-817nd at
least when using CHIRP. I was able to successfully program memory channels
in both FT-871nd's..
*QUESTIONS*
a) is there a known problem with using this version of SatPC32 with an
FT-817nd?
b) Any thoughts of additional troubleshooting steps I could take?
I suspect I just missed something in the setup manual, but I can't seem to
figure out what. Thanks for any help you can provide.

Hi Bill,
Use REV in Doppler.SQF for all linear satellites, as all of these
satellites have a reverse frequency pattern (the only exception I know
of is AO-07 Mode A, Mode B works reverse). The parameter decides whether
SatPC32 changes the uplink frequency in the same direction (NOR) or in
the opposite direction (REV) when you change the downlink frequency. The
parameter has no influence on the setting of REV / NOR on the radios,
i.e. it does not change the setting. I described this in the notes at
the end of Doppler.SQF.

Many thanks Erich and Mineo for the corrected files!
All working for me now, thanks to all. Heard several N. American stations
today on RS-44. It seems I had two separate problems: 1) the incorrect NOR
in the Doppler.SQF file, and 2) I was clicking on RX/TX Freq. Data instead
of Uplink Calibration, as pointed out by George?KA3HSW.

International Space Station (ISS).
?
This will be a direct contact via amateur radio between students at the
Tecumseh High School,Tecumseh, OKand astronautShannon Walker, amateur radio
call sign KD5DXB. Bothonsite and remote access will be provided to the
student body at the time ofthe contact per Covid-19 guidelines. Amateur
radiooperators, using the Tecumseh High School Amateur Radio Club call sign
K5THS,will operate the ham radio ground station for this contact. Students
will take turns asking Walkertheir questions. The downlink frequency for
this contact is145.800 MHz.
?
The ARISS radio contact isscheduled for December 4, 2020 at 12:33 pm CST

Students and staff at all the District?s sites andgrades will have been
involved at different learning levels (utilizing various
grade-appropriateSTEAM class activities) in preparation for the ARISS
contact. In developing theschool?s amateur radio class, the school partnered
with the local radio operators of the Pottawatomie County Amateur Radio Club
and SouthCanadian Amateur Radio Club who were instrumental in providing
equipment,installation, and technical expertise, and who will be on hand
during the ARISScontact. ?
?
Astime allows, students will ask these questions:
?
1. If you could go back to high school, what is one thing you would make
sure you paid more attention to?
2. What was thescariest part when traveling through the atmosphere?
3. Are you longingfor the day you?ll return to earth or already putting on
your brakes so thatyou can stay on the ISS longer?
4. What is one skillthat every astronaut should have before entering the
astronaut program?
5. Have you seen anychanges in your circadian rhythms, or those of any
plants or animals on boardthe ISS?
6. How does NASAtrain you to deal with zero gravity?
7. How do you getdressed without your clothes floating away?
8. How does NASAprepare you for walking on earth after months of being in
space?
9. Is there a sightin space that was breathtaking the first time you saw it,
and what was it?
10. If there is asmall space particle that penetrates the ISS, how is that
handled?
11. What are some ofyour favorite experiments in which you are involved?
12. How much trainingdo you need before going into space?
13. What happens ifyou become sick on an EVA or inside the ISS?
14. What is the mostchallenging plant to try to grow in space?
15. Does time changein space?
16. How do you sleepin space?
17. How do youmaintain body heat in and out of the ISS?
18. If someone isinjured on the ISS, how do you respond?
19. If afree-floating one-ounce drop of water were to freeze in the ISS,
would it berough or smooth in shape?

AMSAT NEWS SERVICE SPECIAL BULLETIN
ANS-337
The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.
The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.
Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

Launch Window for AMSAT's RadFxSat-2 / Fox-1E Opens December 19th
Virgin Orbit has announced that the launch window for their
LauncherOne Launch Demo 2 mission opens on December 19th. This launch
will carry AMSAT's RadFxSat-2 / Fox-1E to orbit.
RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a
partnership opportunity between Vanderbilt University and AMSAT and
will carry a similar radiation effects experiment, studying new FinFET
technology.
RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The
RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a
linear transponder ?upgrade? to replace the standard FM transponder in
Fox-1A through D. In addition, the uplink and downlink bands are
reversed from the previous Fox satellites in a Mode V/u (J)
configuration using a 2 meter uplink and 70 cm downlink. The downlink
features a 1200 bps BPSK telemetry channel to carry the Vanderbilt
science data in addition to a 30 kHz wide transponder for amateur
radio use. Telemetry and experiment data can be decoded using FoxTelem
version 1.09 or later. FoxTelem is available at
https://www.amsat.org/foxtelem-software-for-windows-mac-linux/.
Participation in telemetry collection by as many stations in as many
parts of the world as possible is essential as AMSAT Engineering looks
for successful startup and indications of the general health and
function of the satellite as it begins to acclimate to space. AMSAT
will send a commemorative 3D printed QSL card to the first station
capturing telemetry from RadFxSat-2.
RadFxSat-2 / Fox-1E Frequencies:
Telemetry Downlink - 435.750 MHz
Inverting Linear Transponder Uplink - 145.860 MHz - 145.890 MHz
Inverting Linear Transponder Downlink - 435.760 MHz - 435.790 MHz
[ANS thanks AMSAT for the above information]

I installed FoxTelem 1.09 on a windows PC. When I launch the application
the error message ?Could not write spacecraft user properties file. Check
permission on run directory or on the file.? Don?t know how to fix this
error message. Thanks for guidance.
