FoxTelem 1.02 Released


FoxTelem Version 1.02 is now available for download. Like the last
release, you can patch your installation by downloading the patch file. In
this case it is a single file to replace.

You can download it from here:

Everyone should upgrade to 1.02 because this readies FoxTelem for
transition to the new Telemetry Server which will be more reliable.

Additionally this release fixes a number of issues and adds the ability to
download data from the Server to view/analyze in FoxTelem. If you download
data, please make sure you save it into a separate directory to your local
data, otherwise you will over write it. Of course frequent backups of your
data minimize this risk.

The release notes are below:

* Fixed bug where opening the Fox-1A spacecraft menu would cause a crash
* Added horizontal and vertical lines to the graphs if button clicked
* Fixed Typo on measurements tab
* Fixed a bug where UTC was not displayed for the Diagnostic tables
* Capture the string version of the STP date in ENGLISH for all users, but
leave other dates in local language
* Fixed bug where TCA date could be null and a SERIOUS error was reported
* Fixed issue where the tabs were always refreshed when the spacecraft
menu closed
* Fixed bug where UTC date was sometimes wrong on the spacecraft T0 panel
* Ready FoxTelem for sending server data via TCP
* Support downloading data from the server

New Release of FoxTelem

From the AMSAT Bulletin Board Mailing List:

I wanted to announce the release of FoxTelem Version 1.01. If possible,
everyone should upgrade to this new version. In addition to some new functionality it fixes some bugs and issue that mean more data will be uploaded to the server.

This is a patch release. If you already have 1.00 installed then download
the file

You can download it from:

Only two files have changed (plus the manual). Copy these files into your
install directory
– FoxTelem.jar
– spacecraft/FOX1A_radtelemetry2.csv

You can also download the whole install file and install it in a new
directory. You can use the
settings menu to continue using your existing log files. Ask if you need

Lots has changed in this release and many bugs have been fixed. Please
report any issues
that you see.

Release notes:
* Allow the user to view and set the “track” attribute for each spacecraft
(and other parameters)
* Better doppler tracking in IQ mode and more stable estimate of the
received frequency
* Better Find Signal algorithm with tuning paramaters for experts
* Read Time Zero from the server for each reset and use to plot graphs in
* Set the default fcd frequency to 145930 so that Fox-1A, Fox-1Cliff and
Fox-1D will be in the passband
* Allow the gain to be set on the FCD (rather than hard coded)
* Do not change the FCD LNA or Mixer Gain. Leave unchanged.
* Do not open the FCD unless the start button is pressed
* Fixed a bug where the last 2 bytes of the radiation telemetry were not
decoded correctly
* Allow Vanderbilt radiation experiment to be graphed
* Allow user to select UDP or TCP for upload to the server (but use UDP
for now please)
* Shorten the period between passes so that graphs look continuous
* Ignore duplicate high speed radiation frames – needed for processing
data from the server
* Allow graphs to be hidden so that average or derivative is easier to see
* Notify the user when a new release is available
* Cleaned up the FFT trace with some averaging
* If showRawValues is checked then save CSV files as raw values
* Several updates to the manual

LAPANSAT-A2 to launch 0430UTC 28SEP15 on Indian PSLV-XL C30


Launch Successful and satellite has been heard!

Please send reports to

The 76kg LAPANSAT-A2 satellite is scheduled to launch as a secondary payload of the ISRO Astrosat space telescope mission on an Indian PSLV-XL rocket at 0430UTC on 28SEP15. The satellite is expected to be deployed in a low inclination orbit of 6 to 10 degrees, at ~650km altitude. This means stations North or South of approximately 32 degrees of latitude will not be able to access the satellite, but stations near the equator (such as Indonesia) will have up to 14 passes a day.

Along with Maritime AIS monitoring equipment, and optical capabilities, LAPANSAT-A2 carries a V/U voice repeater (435.88 with PL tone up, 145.88 down) and an APRS digipeater (145.825). The telemetry beacon is 437.425 MHz. The operational plan is not known at this time.

The CAMSAT XW-2(CAS-3) cluster launch of 9 or more amateur radio satellites is CAS3Ascheduled for 23:00Z on September 18th, 2015, or late afternoon/early evening Friday night in the US. The launch is on the maiden flight of the Long March 6 vehicle, from the Taiyuan launch complex.

Satellite separation is planned for 23:15:14 UTC, and the first orbit has the cluster passing over the central US at approximately 00:05Z – 00:23Z XW-2 1st pass19SEP2015.
