 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.  The current system provides that in a passive state, a node has talkgroup 0 or ‘off’ selected.

-Each repeater is independent and can be used locally, with the addition of regional or national capability as required, dependant on the prevailing talkgroups. More than one connection by different talkgroups can be achieved on the reflector.+Each repeater is independent and can be used locally, with the addition of regional or national capability as required, dependant on the prevailing talkgroups.

 There is a proviso that if any of the independent EchoLink or Metar services are in use, the passive reflector link is for the time being suspended, returning to default when those other services are terminated. There is a proviso that if any of the independent EchoLink or Metar services are in use, the passive reflector link is for the time being suspended, returning to default when those other services are terminated.

-First of all, SvxLink is designed by Tobias Bloomberg SM0SVX, firstly around 2006/7, as a means to access EchoLink via a Linux platform, but linking analog modes. AllStar is built around 2013 from Asterisk a PABX package for telephones. (Linking the two systems together while possible is inadvisable.)+First of all, SvxLink is designed by Tobias Bloomberg SM0SVX, firstly around 2006/7, as a means to access EchoLink via a Linux platform, but linking analog modes. AllStar is built around 2013 from Asterisk a PABX package for telephones. As it happens I have made multiple Allstarlink node available as Talkgroups within the svxlink reflector.
  
-In Svxlink, no node numbers are required, just the natural callsign, and password provided to the reflector keeper 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. +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.

 Each node user can update an entry on the svxportal to describe his station for public view, to further enhance his/her presence. HubNet is already available on the UK portal svxportal-uk.ddns.net. Each node user can update an entry on the svxportal to describe his station for public view, to further enhance his/her presence.

-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. A full tutorial is shown here in this link [[https://www.marrold.co.uk/2018/04/converting-cm108-usb-fob-for-amateur.html]].+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.

Yes I did say that twice because you ignored it the first time and wondered why it didn’t work.  Firstly always follow the instructions, NEVER use root to run the software, and always follow the instructions……..

-((The current version of the SVXLink package is Version 24-02.1 and is not yet current available as an dpkg. But this is in the pipeline. If you do find a dpkg on the current version of Bookworm, it is an old version and has several features absent, such as the gpiod functionality, and full connection to the svxreflector.+((The current version of the SVXLink package is Version 24-02.1 and is available as I suggested above as an image.

 +Stop Press:
 +While the image for version 24 is still very much valid, a new version 25 is available either from the author SM0SVX that requires full compilation, or as a script package at the latest post on my web-site g4nab.co.uk. However this is very touchy, and will require some babying into a working condition. Stick with the Image Version 24 for ease of use.

 +I mentioned in the chat that the OARC Radio channel is now available on the svxlink reflector. As a reminder the SVXLink system is FM, but relies on the OARC Digital ASL Reflector to connect. Tests have proved that this has been highly successful method of interfacing..
