If you would like to monitor the system from your PC, you can do so by going to:
Scroll down the page, then click on the link for “Southwest Missouri Linked Repeater System” or you can use the following link for the same location: http://www.broadcastify.com/listen/feed/28023
Click the Triangle symbol under “Listen” and you will hear the activity on SMLRS as it is repeated on the repeater in Springfield (147.015). If you happen to be listening with your radio, you will notice a short lag between what you hear on the radio and what you hear on the internet. That’s normal.
This is a one-way communication link. You will NOT be able to talk back to what you hear or ask questions over this internet connection.
ADDITIONAL TECHNICAL INFORMATION
The SMLRS is a unique system. Its robustness and system reliability stem from high quality system components and true RF links. However, the system designers realize that today there is also a need for linking into the system via the Internet and RoIP protocols.
As described above, the first protocol is for listen only via the Internet. By visiting http://www.radioreference.com/apps/audio/?ctid=1517, you can monitor online. When you arrive at this page, scroll down to the link titled “Southwest Missouri Linked Repeater System”. Select from the dropdown menu the media player you wish to use. Options such as web player, java web player, windows media player, iTunes, Real player and Winamp are available options. Then, click on the speaker icon in the “listen online” column and the chosen player will open and you will be able to monitor SMLRS traffic for as long as you want or need.
The second IP protocol is EchoLink node # 113667, callsign K0NXA/R. The EchoLink node is attached to south Hub linking repeater at Crane, MO – the 442.150 Repeater. When using the EchoLink node, you are able to talk on and receive radio traffic from any repeater on the SMLRS network. To use the EchoLink node, email email@example.com to get added to the “white list” of allowed users.
The third RoIP mode begins our move into the public service realm. It is not a device that amateur operators use for IP communications. All radio traffic from any SMLRS repeater is transmitted out onto the system NXU-2A. The 147.015 repeater is equipped with the system JPS NXU-2A. These devices allow for a 1 to 1 connection unless otherwise programmed. An emergency communications center or mobile command center equipped with a dynamic or static IP and an NXU-2A will be able to connect to the SMLRS system with the proper IP information. There is also a PC client version, called PC NXU that can be obtained from JPS. This software allows a person with a laptop PC and a microphone to connect to the NXU-2A at the 147.015 site and connect to the system as if they were using a radio or another NXU-2A. More information about the NXU-2A can be found at http://www.raytheon.com/capabilities/products/nxu_2a/. If your agency would like to establish a connection via this method, please contact one of our system administrators.
Lastly, the SMLRS is connected to the MoSWIN statewide radio system at the Granby KM0HP 145.390 repeater site via an RoIP connection. Any dispatch console on the system can have the icon placed on their radio dispatch console. Troop D HQ in Springfield is currently equipped to monitor and access the system as needed. Only licensed amateurs are allowed to transmit on this icon, but anyone may listen. This allows dispatchers or radio operators that are licensed amateurs to participate in nets, SkyWarn, or other emergency nets in which amateurs are providing emergency communications with equipment they are familiar with and not a radio that they may have never used. This also allows amateurs to go to a served agency and send and receive data from the SMLRS from local ARES, RACES, etc. groups without that agency having amateur gear installed at their facility.
