Internet RF Modes

Wires-X System Fusion: The STL-Metro Room (#43072) is connected to the 443.075 repeater full time and is a 100% digital room.  Room time out is 30 mins.  Users may change rooms by the Wires-X button on their Yaesu radio, but the repeater will return to STL-Metro after 30 mins.  There are many repeaters connected to the STL-Metro room, notably the 443.775 repeater in downtown St. Louis and the 147.105 repeater in Imperial (Jefferson County).  There are rag chews on Thursday and Friday nights starting at 7pm.

IRLP: As of Oct 2019 the WØSRC IRLP node is currently off the air.  The SLSRC engineering committee is re-evaluating IRLP on the repeater.  We don’t expect it to return before summer 2021.  Node 7106 connected to the 146.850 repeater.  Key using DTMF tones and dial the remote IRLP node number.  73 to disconnect.  Example dial 9900 to connect to IRLP node 9900.

Echolink: WØSRC-R Node 396891 is connected to the 146.850 repeater.

To connect to an Echolink node with 6 digits, for example 123456, issue the following command.  *440105*33123456.  To connect to an Echolink node with less than 6 digits, like 1234, pad the node after the double 3’s with zeros to make six digits like the following example.  *440105*33001234.

To disconnect issue the following command *440105*13123456 to disconnect from 123456.  Also pad your command string with zeros for Echolink stations with less than 6 digits for the disconnect.

AllStar : WØSRC maintains two public AllStar nodes, nodes 49485 and 40105.  The Allstar status page can be found here :

WØSRC node 40105 is connected to the 146.850 repeater full time.

Click here for the WØSRC AllStar 40105 Supermon Page

To connect to another AllStar node issue the command *440105*3<node number>

To disconnect from an AllStar node issue the command *440105*1<node number>

WØSRC node 49485 is a “hub” node, not connected to any SLSRC repeater system and can be thought as a “talk group”.  Any node connected to the 49485 can hear any other node connected.  The Engineering Committee has the ability to connect the 49485 to the 146.850 repeater on an ad-hoc basis.

* AMS (Automatic Mode Select) System Fusion

System Fusion is Yaesu’s digital operating mode.  It only works with Yaesu’s newer mobile and HT radios.  The SLSRC C4FM System Fusion repeaters operate in AMS (Automatic Mode Select).  AMS mode works in Digital Narrow (DN), Wide Voice (WV), Frequency Modulation (FM) and Data.  If you transmit in FM, you will receive in FM.  If you transmit in digital C4FM (DN, WV, Data) you will receive in digital.  If a FM user joins a digital conversation, all the Yaesu radios will automatically switch to FM to continue that conversation.  In FM mode, you must use a CTCSS tone of 141.3 Hz to access the repeater.  If you are operating in FM mode, please check to see if a digital conversation is in progress (BUSY light + S meter bars will be present) before you key up.  If you have a FM only radio, use the CTCSS tone to squelch out the C4FM digital hash.  If you have a “Busy Channel Lock Out” feature on your radio, you might want to turn it on for this frequency.  There is no courtesy tone on the SLSRC System Fusion repeaters & there is a very short squelch tail.  Timeout is 3min.

In Aug 2018 Yaesu put together an “Overview of System Fusion 2” YouTube video that is very informative on C4FM.  I encourage you to watch this video to get up to speed on the System Fusion environment.

In Sept 2018 Yaesu put together an “Overview of DG-ID and DP-ID” YouTube video.  Go check it out to learn more about this ID standard.
