All,
The TLEs for the GRACE Cubesats in the Cal Poly list have been updated.
http://mstl.atl.calpoly.edu/~ops/keps/kepler.txt
Based on these new TLEs it is now certain that AO-85 is object 90747,
GRACE-47 in the Cal Poly list. In the official JSpOC Catalog AO-85 is
object 40967, 2015-058D.

Hi all,
We have almost reached 20 stations already picked up by Duchifat1 that are
displayed on the world map at our web site.
You are all invited to experiment sending a compressed APRS packet with
your location and registration code to the satellite.
These packets can be generated either with a small software converter from
LAT/LON ("APRS Encoder") at our web site or with a Byonics TinyTrak4 for
mobile use or base station.
When using the "APRS Encoder" you also need a conventional TNC, either
external or software to convert the 14 characters long text string to
1200bd AFSK audio for transmission.
The satellite stores the packets and we get to download them from the
satellite at least 3 times a week. The new stations are then added to the
map automatically.
More information and operational tips are in the downloadable files at the
web site.
Good luck & 73!

Hi AMSAT,
I am looking for some guidance regards antenna setup for a fixed
installation to work both FM sats & linear transponder satellites.
My initial thought was:
AZ / EL Rotator
2M xpol beam 5 ele ?
70cm xpol beam 9 ele ?
LNA for both 2M & 70cm receive feeds
...plus some spare space on the boom, perhaps for 3 ele for LEO wx sats..?
I appreciate this will probably cost a few $$ - but hopefully worth
it....obviously
won't build all this in one go..!
Appreciate your thoughts / comments here..?

Rupert,
Your thoughts for setup seem reasonable, you'll probably find it works OK
for WXSats as well without the extra antenna.
I'm using the following for satellites:-
Wimo X-Quads for 2 & 70cms
Yaesu G-5500
Preamps
Seems to work nicely for myself on FM & SSB Satellites and the 2m X-Quad
seems fine for WXSAT decoding as well (using Airspy SDR or the old Rig
RX2).. Only thing I need to add to my setup is the ability to change the
polarity mine are fixed all the time to RHCP.

Using the new GRACE_47 object (90747) for AO-85, I was able to make
several contacts this evening using full computer control of my rig with
SatPC32 v12.8c.
SatPC32 tracked perfectly, keeping my rig on the appropriate uplink and
downlink frequencies for AO-85. I worked a station while the satellite
was at 2.2 degrees elevation over my horizon.
My opinion is that Filter #2 works best for TX and RX with the Icom
IC-9100 on AO-85.

I suppose I have the wrong Keps for AO-85 since I always seem 2 minutes
too late for start and SatPC32 claims she's still below the horizon.
Is it me, or should I find some secret set of TLE's for her ?

"GRACE_47" by CalPoly, with the placeholder number of 90747, and the

Hello All,
My thanks to K4AMG Memorial Amateur Radio Club for allowing me to
rework the club's OSCAR station. It provided me with the opportunity to
make my first satellite contacts today while testing the hardware and
software systems.
My thanks also to N8IUP, K8YSE/7, and N3PZZ for answering my calls on
FO-29.
Now for the stupid question of the day:
I've found the ARRL instructions for editing ADIF files to enable
logging OSCAR contacts via LoTW.
I am running Debian stable and using CQRLOG as my primary logging
software. I also use CQRLOG to upload my contacts to LoTW and eQSL. I
export my CQRLOG to upload to QRZ as well.
Is there any consensus regarding electronic logging of OSCAR contacts?
What, if any suggestions can you all make to aid a new operator trying
to log satellite qso's?

NASA?s Launch Services Program (LSP) has awarded multiple Venture Class
Launch Services (VCLS) contracts to provide small satellites (SmallSats) --
also called CubeSats, microsats or nanosatellites -- access to low-Earth
orbit.
The three companies selected to provide these new commercial launch
capabilities, and the value of their firm fixed-price contracts, are:
? Firefly Space Systems Inc. of Cedar Park, Texas, $5.5 million
? Rocket Lab USA Inc. of Los Angeles, $6.9 million
? Virgin Galactic LLC of Long Beach, California, $4.7 million
At present, launch opportunities for small satellites and science missions
mostly are limited to rideshare-type arrangements, flying only when space is
available on NASA and other launches. The services acquired through these
new contract awards will constitute the smallest class of launch services
used by NASA.
?LSP is attempting to foster commercial launch services dedicated to
transporting smaller payloads into orbit as an alternative to the rideshare
approach and to promote the continued development of the U.S. commercial
space transportation industry,? said Jim Norman, director of Launch Services
at NASA Headquarters in Washington. ?VCLS is intended to help open the door
for future dedicated opportunities to launch CubeSats and other small
satellites and science missions.?
Small satellites, including CubeSats, are playing an increasingly larger
role in exploration, technology demonstration, scientific research and
educational investigations at NASA. These miniature satellites provide a
low-cost platform for NASA missions, including planetary space exploration;
Earth observations; fundamental Earth and space science; and developing
precursor science instruments like cutting-edge laser communications,
satellite-to-satellite communications and autonomous movement capabilities.
LSP supports the agency?s CubeSat Launch Initiative (CSLI) by providing
launch opportunities for more than 50 CubeSats that are awaiting launch
during the next three years. The VCLS contracts will demonstrate a dedicated
launch capability for smaller payloads that NASA anticipates it will require
on a recurring basis for future science SmallSat and CubeSat missions.

The other morning I attempted AO-85, listening to the down link on
145.980. I just sat down and listened to the recording of that pass. At
the time I thought I was not making it into the sat, but upon listening to
the recording I found that I indeed was making it, and at times quite
strong. I was using the Arrow, two FT-60's, and headphones, but during the
pass I could have sworn I was not making it, as I was not hearing
myself...just squelch. I did learn from that pass though that AO-85 was
much clearer on 145.975 in the latter stages, or after it passed the posted
Max El for that pass.
Just wondering if anyone else experienced the same scenario as I. I did
tweak a few things with coax and radio programming last evening, and that
seemed to make a noticeable improvement on the SO-50 (03:07Z) pass last
evening.
Have a great day everyone,

A handheld receiver will sometimes be a little too sensitive with this type
of configuration where you are using the same mast for the UHF and VHF
antenna together. The front end of the receive HT will have a tendency to be
a little desenced causing a slight reduction in audio quality on your
downlink. This might be what you were experiencing.
What were you using to do the recording? Was it not the same radio as what
you were listening to for downlink?

Max El for that pass.
Just wondering if anyone else experienced the same scenario as I. I did
tweak a few things with coax and radio programming last evening, and that
seemed to make a noticeable improvement on the SO-50 (03:07Z) pass last
evening.
Have a great day everyone,

The SatNOGS project has a database component with a nice API for querying
sat information. It is an active project, so it is far from a one-stop
machine-queryable resource. But that is a stated goal of the component.
https://db.satnogs.org
(add "/api" to poke around what is query-able at the moment)
I'll be at the Symposium this weekend along with a few of the SatNOGS
people flying in from Athens, Greece, who will do a talk. IIRC they will
be bringing some of the hardware also. In-person would be a great time for
lots of discussions.
As an open project, in practice things get done by someone doing it.
Feature requests are nice, but a request accompanied by code is better.
Everyone currently involved has a day job :) Let's work together!
