Southwest Missouri Linked Repeater System On-Line

The year-long project to complete the Southwest Missouri Linked Repeater System (SMLRS) discussed a year ago last January was completed yesterday when the 145.390 repeater went live in Granby, just SE of Joplin.

All 3 of the repeaters on the system are linked together 100% of the time via RF, so when you key up to talk on one repeater, you are talking on all 3.  If you don't have the repeaters programmed yet, here are their frequencies if you want to try them out:

Springfield - 147.015+ PL 162.2 Hz
Granby      - 145.390- PL  91.5 Hz
Crane       - 442.150+ PL 162.2 Hz

The system has an IRLP node #7191, that links the system to the Central Region Intertie System (CRIS) for the net on Thursday nights from 7:00 p.m. to 9:00 p.m.  The IRLP node also has the capability to link directly to the 146.700 SkyWarn repeater in Lees Summit should the need ever arise.

If you would like to monitor the system from your PC, you can do so by going to and search for "Southwest Missouri Linked Repeater System", or you can click this link:

System documentation for end users, net control operators and for training purposes will be forthcoming in the near future for those wanting to use the open system for public service events, such as the MS150, or any other weather or disaster related activities.

The system is a combined effort between the Southwest Amateur Radio Group in Neosho, the MSHP amateur radio club, and the Nixa ARC and partnerships with the City of Crane, and the Greene County EMA were formed in the process.  

Last night, we had a station in Nevada check into the system, and we talked to Ray, KB0STN, in Joplin.  He was at the Joplin ARC club meeting inside the EOC at the Red Cross building on his HT and was full quieting.  There have been several stations this morning roaming around Joplin checking coverage.  On my travels north, I was able to work the repeater on I-49 to about 8 miles south of Nevada, and then again in Nevada and for a ways north of town.

Thanks to everyone that helped with the system, whether you were on the ground doing the work, or one of those many local hams that donated cash to help complete the system, or one of those that obtained grants to purchase parts for the system.  It was a team effort and could not have been done in such a short time without everyone pitching in and helping.

73 & enjoy,
