Thanks for the new software. Sounds like a lot of work has been going on in the background.
One question..........Will version 1.02 still send data to the server or will it simply stop working as did 1.01 after the last update?

Subject: [amsat-bb] FoxTelem Version 1.03 released

This version of FoxTelem uses a new datafile format.  While we store our
data on
the server in an SQL database, we use a flat file database for FoxTelem.  A
file format is nearly optimal for a program that mostly adds new data to
the end
of a growing list.  With that said, we need to be able to load sections of
data into memory for efficient analysis.  The new data file format allows
If you have been downloading data from the server for analysis, you will
that this format is much faster.

One major change is the ability to automatically switch between low speed
high speed.  This will help unattended stations gather as much telemetry as
possible.  The "auto" mode actually runs both decoders at the same time, so
sure your computer has enough CPU power to cope.

Graphing has been updated to support better analysis of the spacecraft by
AMSAT Operations team and amateur scientists everywhere.

This version also contains new features that will be required for
and Fox-1D.

You can download it here:

Version 1.03 Changes
 * Support larger volumes of data with much better speed in a segmented
 * Auto detect high speed vs low speed telemetry
 * Allow the user to swap IQ channels in IQ mode
 * Allow graphs to be plotted as points (without lines)
 * Plot more labels on horizontal axis when many resets plotted and fixed
some graph formatting issues
 * Graph formatting parameters are saved to config and reloaded when
FoxTelem is restarted
 * When reset button pressed on graphs the average period is reset too
 * Swapped min/max values for solar panel temp on 1A
 * Fox-1A Solar panel voltage was (incorrectly) using the MPPT conversion
 * Fixed bug where HighSpeed Frames were unnecessarily held in the queue
until the pass was finished
 * Cap max RSSI in the lookup table at -140dB to avoid spurious readings
 * Interpolate the middle of two samples for first difference calculation,
for more accurate TCA calculation
 * Add SAFE mode bit to the Computer panel so that it can be graphed
 * Fixed bug where Radiation Graphs did not open at start up
 * Fixed bug where T0 file could be corrupted if URL returned bogus data
 * Fixed bug where FoxTelem gave many error messages but did not quit if
the log dir was not writable
 * Skip NULL values for some measurements.  Don't plot continuous labels to
left of vertical axis.
 * MEMS diagnostic values are now in dps (vs Volts)
 * Fixed bug where radiation data could not be saved to CSV files
 * Fixed bug where FindSignal failed to lock if Track Doppler was not

It also provides Support for Fox-1Cliff and Fox-1D:
 * Display HERCI High Speed frames on the Herci Tab
 * Display HERCI Housekeeping frames
 * Support the Fox-1D low res camera format
 * Implemented MPPT panel temperature conversion using Cubic fit
 * Sort camera images by reset and uptime not picture counter
 * Save position of the HERCI HS tab horizontal divider
 * Allow the user to specify the number of thumb nails to display on the
camera tab
 * Display converted HERCI Housekeeping data
