SvxReflector (formerly also called "Östkustlänken") is a National Network of Swedish analogue Repeaters, which is linked together with the help of SvxLink , usually over the Internet.
In the network, talkgroups used to separate the traffic. A talkgroup can be likened to a logical "channel".
On the other hand, a repeater can never be active on more than one Speech Group at a time.
Incoming traffic on a monitored Voice Group will start the repeater automatically, but cannot normally break in during an ongoing QSO.
Repeaters and Simplex nodes in the network monitor statically:
The entire system can be monitored in real time via the Svx Portal (this website).

If you want to use a specific Speech Group, it can be selected in two ways - with DTMF or Subton (CTCSS).
If no traffic occurs on the selected Talkgroup, the system switches to idle mode after 30 seconds (adjustable by sysop) and waits for activity on monitored speech groups. A small "FLIRRP" is heard when the repeater or simplex node returns to its default position. On SK7RFL, SK7RN and SK5BN, this always happens in connection with the Repeater closing down.
To activate voice group 2405 with DTMF, press:
912405#
The repeater will announce that it will switch to Talkgroup 2405 when you release PTT.
A list of talkgroup that can be activated with Subton can be found here on the SvxPortal .
To activate eg talkgroup 2405 with Subton, CTCSS, select Subton 91.5Hz. After the first broadcast session, Tepeatern announces which Speech Group it will switch to when you release PTT.
Activation with a subtone can only take place from the repeater's sleep mode, ie not during the current QSO.

Program several memory channels with different Subtones, in order to be able to activate the Repeater / Simplex node with the correct talkgroup directly.
For those nodes that have a Subton that is not connected to any talkgroup, column local in the list, services on the node can be used without any Voice group being connected. It can be practical for using various modules in SvxLink such as parot, EchoLink, Voice mail etc. It also makes it possible to have local QSOs on the channel, without any Speech group being activated from outside .
In the same way as when a Voice Group is active, it is required that the channel is dormant for a time before connection of voice groups can take place, both remotely and with a subtone. The time is adjustable by sysop, but is by default 30 seconds.
However, it is always possible to activate / change talkgroup with DTMF commands at any time.
During a QSO on one Speech Group, it is possible to move all active nodes to another Speech Group. The active node is the node that has had local activity since the talkgroup was activated, ie that the noise barrier has opened at least once.
The QSY function is controlled by DTMF commands.
| 92 # | QSY to a random number group that is automatically selected by the reflector server |
|---|---|
| 92nnn # | QSY to speech group nnn |
| 93 # | Follow the latest QSY |
QSY for temporary speech group is suitably used in such a way that calls to a beginning are made on a broader speech group, eg 240 for the whole of Sweden. When all participants have called in on the talkgroup , the QSY command ( 92 # ) is used - to move all active nodes to the temporary speech group. The wider number group will then again be free for calls.
An automatic QSY is also performed on talkgroup 240, after 5 minutes.
QSY to a specified Speech Group can be used to add more nodes to an ongoing QSO. Assume that a QSO has started on talkgroup 2403, ie SM3. Under the QSO, you want to expand with nodes in SM5 as well, ie Number group 2405. The command 922405 # can then be used for this. All nodes that are currently active on 2403 will be moved to 2405 and all nodes that monitor 2405 will connect to the speech group.
In newer versions of SvxLink, you can very easily follow a QSY. When QSY occurs, the repeater says " QSY 24099nn pending ". If you press PTT within about 15 seconds, the repeater will follow this QSY. Otherwise the repeater says " QSY [24099nn] ignored ".
A passive node can also be manually made to follow the latest QSY with the command 93 # . This can be good if you have not had time to send before QSY took place or had time to press PTT within 15 seconds after QSY.
Note the difference between QSY and local choice of TG.
| Command | Example | Description |
|---|---|---|
| 91nnn# | 912405 # | Activate Speech Group (2405). |
| 91# | Jump back to the previously selected talkgroup . On SK7RFL, SK7RN and SK5BN = activate standard number group. | |
| 92# | QSY all active nodes to a random talkgroup automatically selected by the Reflector. | |
| 92nnn# | QSY all active nodes to a specific talkgroup | |
| 93# | Follow QSY if you have just listened. Also PTT within 15 seconds after QSY Pending . | |
| 94nnnn# | 9424070# | Temporarily add extra talkgroup monitoring |
| 9*# | Information / Status (talkgroup ) | |
| 1# | Activate the Parrot (ends with # ). | |
| 2# | Activate EchoLink (ends with # ). | |
| 5# | Weather (METAR) for nearby airport. | |
| 0# | Help |
The SSA bulletin can be sent out locally on each repeater. There are also two bulletins in the system, which can be listened to over all or parts of the network.
If the local Repeater does not monitor the desired bullet number group, this can be added with the command 94 as above.
The mapping between Subtones and Talkgroups is according to SSA's list for CTCSS. The second tone in each district (Secondary 1 ) is mapped to talkgroup for that district.
If you want to disconnect a talkgroup directly, without waiting 30 seconds, you can press 910 # (TG0). Good to use if you happen to choose the wrong Speech Group.
You cannot activate several talkgroup at the same time.
If you have activated a specific talkgroup, for example TG2403, traffic from other talkgroup will be blocked until the traffic has stopped on TG2403 and 30 seconds have passed.
The SvxReflector is not connected to DMR / Brandmeister, but uses similar names and numbers on talkgroup.
