 With a passive connection to a server, users on a connected node can dynamically connect, using a stream of DTMF tones, to another node or nodes equally passively connected, on a system of Talk Groups, that each node can monitor within their configuration.
-The current UK reflector [[https://portal.svxlink.uk:8443]] together link with its partner hub [[https://Yorkshire.svxlink.network]] is effectively a super repeater, linking nodes and repeaters across the world, with local talkgroups and several distant fixed talkgroups formed of Allstar Links, such as Ham Radio 2.0 (YouTube channel), The US EastCoast Reflector, and more locally the North West Allstar Group.
+The current UK reflector [[https://portal.svxlink.uk:8443]] together link with its partner hub [[https://Yorkshire.svxlink.network]] is effectively a super repeater, linking nodes and repeaters across the world, with local talkgroups and several distant fixed talkgroups formed of Allstar Links, such as Ham Radio 2.0 (YouTube channel), The US EastCoast Reflector, and more locally the North West Allstar Group, and naturally the OARC group. Here the OARC talkgroup links to the OARC Allstar Nodes which in turn cross-modes to the DMR talkgroup 2348479. So every user of that talk group is emerging into the svxlink network. It then remains for each Sysop to manage his available talkgroup list, to permit talkgroup 47920 (OARC) to broadcast on his/her repeater.
 The current system provides that in a passive state, a node has talkgroup 0 or ‘off’ selected. By calling by DTMF 91235#, on a node… 91 meaning ‘standby, a talk group follows’ 235 ‘ talk group’s # ‘activate’, the node makes the reflector server open a dynamic path to all nodes that have 235 in their monitoring list. Thus a user can now be heard on all nodes that have 235 included.

 In Svxlink, no node numbers are required, just the natural callsign, and password provided to the reflector keeper by the node builder for the passive connectivity. The reflector maintains the callsign information in a dataset that is displayed by another software package called SvxPortal that can be viewed publicly here [[http://svxportal-uk.ddns.net:81]], so users can view the available stations and the talkgroups available.
-Each node user can update an entry on the svxportal to describe his station for public view, to further enhance his/her presence. A number of All-star Links as Talk Groups are already available on the UK portal svxportal-uk.ddns.net. One such device is produced from one of our own members here.

 To build a node, all that is required is almost any spare transceiver, a raspberry pi and its power pack, a 16 Gb SD card, a CM108 USB sound card, a 10K 1/4 watt resistor, and a 2N2222 transistor, or CM108 Dongle, A full tutorial is shown here in this link [[https://www.marrold.co.uk/2018/04/converting-cm108-usb-fob-for-amateur.html]].
