We have just replaced the program version in the site with the original
files, so no need to rename the files anymore.
You might need to refresh or clear your browser's history in order to get
the right file downloaded again.

We are sorry for the inconvenience caused by that!

>  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!
