Today, 9/12/2019, on the 16:26 UTC pass of AO-92 and the 16:36 pass of
AO-91, the guy was back whistling and whispering into the mic.? He has been
active for a couple of weeks. I wonder if he used to work the SSB birds and
is trying the FM birds with the same method of trying to find himself on
full duplex, like he did on the SSB birds? At first I thought someone had
the VOX turned on, but now I don't think he can hear himself. If anyone
knows who he is, I think any of us would be willing to help him. At least, I
would. So, sir, if you are reading this, please contact KC9UQR and lets
talk.? Brad KC9UQR, Franklin, WI

I concur with JoAnne's write-up.
In my case, and this applies to all my laptops, I have had to open
nasabare.txt in Wordpad and change the font size so all lines are on single
lines and not split up.Only then did Nova import the nasabare.txt correctly
without complaining.?? Not sure if anybody else had the same issues, just
passing it along.
Love Nova for the excellent graphics. Reading through the manual to learn
all that is under the hood is a must!?

Nova also downloads KEPS files from the internet without needing to
create/edit a file.
In the Nova main window click on
? Kep. Elements
? ? Internet Update
? ? ? Configure Download
In the configure window that opens:
Fill in 'Download To:' with where you want to store the download
on your local machine. (I just put it on my Desktop)
Fill in Remote URL: www.amsat.org
Remote files: Click on the 'Edit the file list' icon to the
right of the data window.
When the file list opens uncheck all of the existing options
since those files don't seem useful to retrieving amsat keps.
Then you might need to use either Add, or Replace to enter
amsat/ftp/keps/current/nasabare.txt
Then save the changes with the Nova OK buttons in the layers
of these menus you just negotiated through.
Try the Kep. Elements -> Internet Update -> Start Download
I've found that Nova running in true windows OS fashion may
require to stop/restart the program so don't be surprised.

BG2BHC reported on Twitter that Taurus-1 launched today on the CZ-4B
launch from Taiyuan Satellite Launch Center. Taurus-1 carries an FM to
Codec2 repeater that operates using the same protocol as LO-90
(LilacSat-1) and can use the same software (after frequencies are
changed). The uplink is 145.840 MHz up and the downlink is 436.760
MHz.
CelesTrak currently has three objects from the launch cataloged out of
an expected four. Two objects are in a circular orbit that seem
unlikely for a CubeSat given international orbital debris stations
(750 km x 730 km). The third cataloged object, Object D is a more
likely candidate in a 738 km x 453 km orbit with an inclination of
98.7 degrees. The currently cataloged objects are 2019-059A,
2019-059B, and 2019-059D. TLEs can be found at
https://celestrak.com/NORAD/elements/tle-new.txt
For more information about this unique analog uplink, digital downlink
system, see my AMSAT Journal article / Symposium paper about LO-90 at
https://www.amsat.org/wordpress/wp-content/uploads/2019/03/N8HM_LilacSat_LO-90

Greg,
Point well taken but for my situation you are wrong.
When I open the file in Notepad it looks just fine. But when I try to import
it into Nova it does not like it. It gives me an error.I am just passing
this along if it happens to others.
This happens on the six computers that I own.The only way, again for my
situation,? to fix that, is to open the file in Wordpad,
Downgrade to a smaller font size, then re-save the file, then import back to
Nova. This works perfectly every time I do it. So issue.
Feel free to open the file in Wordpad and you will see the lines are broken
and need to be adjusted. I just tested this at work.
End of topic. Let's move on.

Small correction: FM uplink is on 145.820 MHz, downlink on

BID: $ANS-256.01
Amateur Radio Digital Communications (ARDC) Awards Generous Grant to
ARISS
Amateur Radio Digital Communications (ARDC) has awarded a very
generous grant to ARISS for the Next Generation radio system. ARDC is
the owner and manager of the Internet network known as the AMPRNet. In
June of 2019, ARDC initiated a philanthropic endeavor to provide
monetary grants to organizations, groups, projects, and scholarships
which have significant potential to advance the state of the art of
Amateur Radio, and digital communications in general.
The ARISS Next Generation radio system (or Inter Operable Radio System
- IORS) will support easier radio mode transition, to enable new,
exciting capabilities for hams, students and the general public
including:
+New amateur radio communication and experimentation capabilities,
including an enhanced voice repeater and updated digital packet radio
(APRS) capabilities.
+Slow Scan TV (picture up and downlinks) in both the US and Russian
segments of ISS.
+New multi-voltage power supply will support present and future radio
capabilities and allow wireless experiments to be conducted.
In July, the Inter Operable Radio System successfully completed a
battery of stressful tests required as part of the final certification
of the hardware for launch to and operation on the International Space
Station. Final assembly of the flight safety certification in
preparation for launch is now underway and ARISS is working towards
launch ready status by the end of the year.
For more information on the award please see:
https://www.ampr.org/g2019-09-01a/
To contribute to ARISS and the IORS please see:
https://www.ariss.org/donate.html
ARISS and AMSAT thank ARDC for their generosity in supporting this
important project.
[ANS thanks ARISS, the AMSAT office, and ARDC for the above information.]
In addition to regular membership, AMSAT offers life memberships,
and sustaining donors to AMSAT Project Funds, will be eligible to
receive additional benefits. Application forms are available from
the AMSAT Office.
Primary and secondary school students are eligible for membership
at one-half the standard yearly rate. Post-secondary school students
enrolled in at least half time status shall be eligible for the
student rate for a maximum of 6 post-secondary years in this status.
Contact Martha at the AMSAT Office for additional student membership
information.

Hello all!
As camera and downlink on 435.354MHz operates smoothly, we have
commanded the camera to take picture and store it into memory every
10minutes, this mode should last from now for 7 days or at least to next
commanding session on Monday. The transmitting counter, which selects
picture for downlink is not sychronized with the camera, so there is
uncertain delay between acquiring a picture and its transmission of max.
64minutes. Every picture will be downlinked just once so every reception
counts. Of course downlink is not operating during eclipse.
Further info on https://github.com/alpov/PSAT-2/blob/master/README.md
Enjoy the experimenting!

Based on others' reports and my observations this morning, 2C has a bad
problem.
I could see the passband popping on for about 1/2 second and then going
quiet for maybe 15 seconds, repeatedly. When it was on, it was rx'ing and
transmitting properly.
I timed one of my voice transmissions to coincide with the "poppiing on"
for 1/2 second and hear my voice quite clearly.
This was at about 11:40z this morning.
