With the move of FREE STAR* systems from NATRUST to ircDDB, user registration is no longer required. Users self-register with the ircDDB network when they first transmit on an ircDDB enabled repeater. ircDDB clients (such as g2_ircddb) incorporates a pattern matching algorithm, which is used to validate each user callsign before allowing the user’s DV data to propagate through the system.

You can view live ircddb traffic by checking out the web site here. Note that you must first OPT IN to seeing your data on that page by following the VIS_ON procedure here.

To operate on GB7BD you will need to set your radio up in the following way:

Receive frequency: 439.450MHz

Split: 9MHz ( Transmit fequency 430.450MHz )




Depending upon what you want to do ( linking, routing etc. ) then you set the UR field to different things. Here are some examples:

UR:_ _ _ _ _ _ _ I ( 7 spaces and a capital letter “i” ) Keying the PTT will provide a voice and text response detailing the link status

UR:_ _ _ _ _ _ _ E ( 7 spaces and a capital “E” ) will provide an echo test function so you can check your voice quality

UR:XREF005AL will link the node to XREF 005 module A

UR:_ _ _ _ _ _ _ U ( 7 spaces and a capital “U” ) will unlink the node from whatever its linked to

UR:REF016BL will link to REF 016 module B

The system also supports DTMF dialling for linking, unlinking and querying the status.

To query the status, dial 9 9

to unlink dial 7 3

to link to, for example, XREF005A dial #005A

to link to, for example, REF016B dial *016B

To link the repeater module to an ICOM G2 system running dplus, set URCALL = the repeater callsign, followed by the module in the 7th position and the command in the 8th position of URCALL – e.g., to link to WC7SO module C, set URCALL = WC7SO CL. Note that there is a space between the ‘O’ and ‘C’ since WC7SO is a five letter call.

Note that once the link has been established, users should set URCALL = CQCQCQ. On the IC-E92 a long press on the 0 key will do this.
