FREE STAR* is an experimental approach to the implementation of a vendor neutral, and open source, digital communication network.

FREE STAR* enables existing (FM) repeater owners to establish a D STAR repeater with a choice of interface hardware (GMSK modem or sound card), software and radio hardware.   FREE STAR* currently does not bypass the need for an end-user to own/use a D-STAR radio to access DV enabled repeaters!

The following USB sound card has become the defacto standard for sound card based systems.

A variety of GMSK modems are available.  We have tested several of them.  The following modem passed all of our qualification tests (see the v7 page):

http://www.d-star.asia/index.html.en

We also support the DSP based modem from the dvrptr team in Germany (www.dvrptr.de) - this new addition provides superior front-end sensitivity at a very competitive price point. Thanks to Pierre, VE2PF for uploading this video:  http://youtu.be/0Ly5xFGBFXQ

Additionally, we support the DVAP device, which can be added to a FREE STAR* system either as the principal RF access point or a secondary access point (RF module).

We offer a complete ISO image allowing prospective clients to build a complete system in about one hour.  We also offer an install script allowing for the FREE STAR* software components to be added to an existing CENTOS 5.x box, such as an existing Asterisk / app_rpt (ACID) installation. Hence we enable Allstar node owners / administrators the capability to operate a FREE STAR* system with next to no additional hardware and investment.

September 4,2011:  FREE STAR* Appliance now available.  A HP thin client (T5710) has been successfully converted running CENTOS off a 4GB microdrive.  This client is running the full complement of FREE STAR* software, 2 RF modules (one half duplex and the second a full-duplex repeater).  The HP Thin Client is an extremely cost effective solution, used devices can be found for as little as $28USD.  The conversion cost is an additional ~ $16.  The HP Thin Client can operate off a 13.8VDC supply, it has no moving parts, draws about 600mA @ 13.8VDC and makes an excellent appliance for installation at remote repeater sites.

Please refer to the ISO page to download the above images / install scripts / Quick Install Guides.

October 22, 2011:  FREE STAR* Dual Mode DV and FM solution refined.  We have refined our dual mode (DV and FM) repeater solution.  Yes! - we have a solution that allows an existing FM repeater to be used as a DV repeater as well.  There are many benefits of using Digital Voice.  We feel that the following recordings will 'speak for themselves'.  Thanks to Reg, VA3JQA, for assisting with these tests and providing consent for these to be posted on this website.  The recordings compare a portable station running 1W on FM versus 1W on DV from the exact same location into the same dual mode repeater:

The table below is a work-in-progress attempt to provide the user community with a view of FREE STAR* repeater presence and access information:

(Please note that Half Duplex Access Points require the user's radio to be in duplex mode (+/- DUP enabled with a 0MHz offset), set RPT1=Callsign as shown, and RPT2 = Access Point Callsign with a 'G' in the 8th position - so for example for VE3FSR, set RPT1 = VE3FSR B, RPT2 = VE3FSR G).

D STAR repeaters associated with a third-party production Trust server, will not be able to connect to FREE STAR* systems using dplus.    ICOM repeater systems can add dextra_srv on top of their ICOM G2 and dplus installation without risk of repercussion from their Trust team.  Once this add-on software has been added to your ICOM system, you can then access FREE STAR* repeaters and XRF reflectors using dextra_srv *regardless of the Trust server that either system might be associated with.*

The database on FREE STAR* Reflectors is a hybrid database merging the USroot, Multi-Trust and NATRUST databases into a single database.  The sync and merge process takes place automatically.  This approach enables our reflectors to be open to all. 

If you are having difficulty connecting to any of our reflectors, please contact us at dextra {at} va3uv.com.

Regular D STAR repeater owners (connected to a production Trust server) may connect to XRF reflectors to participate in testing and assessment.  This requires some add-on software to be installed on your G2 gateway PC.  The software is independent of other add-on software (such as dplus) and does not interfere with dplus operation; there is no cross-connectivity.  The following ICOM D STAR repeaters in Canada have been configured to access dextra enabled repeaters and reflectors:

VO1ILP - St. Johns
