Great response Ray, but I have to correct this point. AMSAT, and AMSAT
alone, paid for the launch of Fox-1Cliff (this summer) and Fox-1D, via a
contract with Spaceflight Services. Donations to AMSAT in support of this
expense are very much welcome.
AO-85, AO-91, and Fox-1E were or will be NASA sponsored ELANA launches.

Another motivation for frequent TLE updates for ISS is the narrow
beamwidths of dish antennas used for 2395 MHz HamTV. Even without
orbital maneuvers ISS TLE accuracy can degrade enough to cause antenna
pointing problems within a week.

ARISS APRS Packet Currently Non-Operational
An unidentified anomaly involving the radio serving the ARISS APRS Packet
System on board the ISS has led to the system not functioning. A similar
problem has occurred on other occasions and solutions that resolved the
problem proved to be only temporary fixes. The system may return to service
as it has in the past or it may have finally failed completely. ARISS sees
the delivery of the interoperable radio system as the true solution to
securing our ARISS packet operation. Current target period for delivery and
installation of the replacement system is Fall 2018. In the meantime, ARISS
continues to investigate the problem and seek opportunities to resolve the
issue. The ARISS team knows many amateur radio operators really enjoy using
the ARISS APRS packet system, and thanks everyone for understanding the
issues involved with not having it available.
About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and the National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies and
amateur radio. For more infor
mation, see www.ariss.org, www.amsat.org, and www.arrl.org.

Oops. I did miss that. But the mention of needed donations to AMSAT in

Looking for a portable radio that I can do linear sats with. I settled on an
ft-817, then I went to my club meeting last night and saw a demo on system
fusion.
Does anyone know if Yaesu makes a radio that will work for the linear sats,
that also can do system fusion?
Thanks

The FT-991. I know a few people who use them for sats, including K3RRR I
believe.

For those who receive the DKARS magazine, there is a very interesting
article. The transceiver described is for ATV, but it looks like like it
will tune to the AO-92 uplink frequency. Seems to put out 400mw FM out. I am
not able to take time now to review deeper (stealing away from work) but I
look forward to parsing through the schematic/links this weekend. I am
forwarding this notice for anyone who will be able to get there sooner. I
think there is some potential here, and I would like to know other? opinions.

?I am releasing version 1.06 of FoxTelem today. This release addresses
several defects and instabilities in FoxTelem 1.05 and earlier. It also
introduces a new Earth Plot that allows any telemetry value to be plotted
as a heat map
against a map of the earth. For more details about the Earth Plot and some
example plots, you can read a quick tutorial that I have written here:
http://www.g0kla.com/workbench/2018-01-26.php
As always, let me know if you see any issues or log them on github at
https://github.com/ac2cz/FoxTelem/issues
KEY CHANGES
~~~~~~~~~~~
* EARTH PLOTS allow you to plot any telemetry value as a heat map on a
map of the earth
* Allow graphs and telemetry results to be searched with UTC dates and for
ranges of uptime/dates
* Allow stepping through the telemetry with up/down arrows
* Prevent hang when decoder starts if FCD returns an error
* Fixed bug where TLEs were not updated in the name is changed in the
spacecraft
settings window
* Fixed crashes introduced in 1.05 release
* Display all HERCI High Speed payloads when Raw Byte Payloads showm
* Fix bug where missing TLE disables spacecraft from being tracked at all
* Fixes bug where DDE connection to SatPC32 fails with European decimal
point
format
* Add MPPT calibration values for Fox-1D
* Improved the RF signal measurements
* Improved the Find Signal algorithm
* Space graph labels more evenly
* Put the spacecraft tabs in FoxId order
And many other bug fixes. Full list of changes here:
