I downloaded and unzipped the ground station software, but I can't get it to 
work, as my computer doesn't recognize the .GGG extension on the files.
However, I can report that I did receive the Morse beacon "hi de Duchifat" 
at around 1616 UTC. QTH here is EM79ji.

> Hi all,
> DUCHIFAT1, the Israeli high school students 1U Cubesat is ready for first
> public tests.
> People with the ability to send Compressed APRS location packets are
> invited to join the tests.
> The satellite will collect these packets worldwide along its flight at
> 620km high orbit, and will downlink them from time to time over our ground
> station in Herzliya/Israel.
> Participants are kindly requested to register in advance in order to get
> their packet identified on the map.
> The packets successfully received will be displayed on a map in our
> Internet site and  QSL cards will be sent via Bureau to the stations
> registered and recognized. (unfortunately, there is no way we can 
> recognize
> packets from unregistered stations because the packet is limited to 14
> character at the satellite, so we assign two unique characters to every
> registered station to enable us to identify them).
> Registration can be done at www.h-space-lab.org
> Also available in that site are operational information about the
> satellite, and the following documents:
> *Configuring TT4 Explanation.doc* - how to use the Byonics TinyTrak4 for
> generating Compressed APRS packets
> *Terms Of Use.doc* - terms and techniques for making the best use of the
> satellite
> There is also Ground station software available for download, written by
> our students around ISIS space Demodulator software.
> We hope many people will find it interesting and enjoyable,
> good luck!
