Repeater Upgrade – 146.625 Yaesu Fusion

July 2021

Wires-X linking has been stabilized, defaulting to room SOMN-NET 40861. This room provides excellent coverage of the southern Minnesota area. W0AMX provides a nice listing of currently active rooms which one can connect to by entering or selecting the node number in your radio. The repeater will return to SOMN-NET after 10 minutes of inactivity.

Update September 24, 2020

Wires-X has been in testing for a little while and appears to be functional. This linking technology requires one to select between analog and digital at the time of configuration on the repeater itself. It is presently set up for digital only which means that analog traffic on the 146.625 repeater is NOT linked. I’ve been playing with which system to link 625 to by default or whether to let it simply disconnect after a period of inactivity, will be speaking to those who are currently using it to get a feel for how we’d like to have it set up going forward

Update: August 25, 2020

The YSF repeater is on the air! 146.625 has been upgraded and is running barefoot at this time at 20w. The amplifier requires a small modification in order to work with the new repeater, and that has not yet been performed. Wires-X/Internet linking is now available We have some additional configuration work do in order to bring that online. Stay tuned!

Update: August 12, 2020

Yaesu approved our application for the DR-2X Fusion repeater, shipped it, and it has arrived! The repeater accessories for Wires-X linking are in transit. I hope to have this on the air by the beginning of September, though Wires-X linking may take a bit longer. The repeater will be configured to default one of the Southern MN reflectors but users can change that as needed with a YSF digital radio.

We’re planning to run this repeater in its “Fusion” mode, where it will freely switch between repeating analog FM and repeating C4FM digital. This comes with a couple of side effects:

  • When the new repeater is put into place we will definitely want to have tone squelch turned on for FM radios when listening to 625 unless of course you find C4FM to be a soothing sound, hi hi… Once tone-squelched, the FM radios will ignore digital transmissions.
  • Additionally we’ll all need to learn to check the S-meter on our FM radios for ongoing transmissions so we don’t accidentally step on digital users.

May, 2020

It has come to the attention of the Tech Committee recently that we have a unique opportunity to replace and update the 625 machine. In the last several years Yaesu has been offering their “Fusion” repeaters at a fairly decent discount. Their play is to get Fusion digital repeaters out to as many clubs as possible in hopes that Fusion radio sales will follow, and it seems to be working..

We’re looking specifically at the DR-2X The benefits of this upgrade include:

  • Modernize the repeater and increase stability, its last upgrade was 2004.
  • Maintain Analog FM operation on 146.625
  • Add the capability to pass C4FM Digital “Fusion” mode
  • Add the capability to join Wires-X, via the HRI-200 linking with several other counties around us.
  • Repeater will be frequency-agile and COULD be used on VHF or UHF if we ever desire to do so.
  • Can be used with an external controller if we want to add bells and whistles.

Not all of the equipment will be replaced at this time. We’ll be using the existing:

  • Duplexers
  • Feedline
  • Antenna

The existing KRP5000 repeater + CAT1000 controller was purchased in 2003. It has been a very solid machine and was recently re-aligned. The controller, while flexible, is also a bit dated.


  • DR-2X Repeater: $700
  • HRI-200 Wires-X device: $125
  • FVS-2 Voice Synthesizer: $35
  • PC for Wires-X Linking: ??
  • Shipping: ??

We expect all total to be under $1200 for this upgrade.

Repeater Update – 146.820 August 23, 2020

The antenna and feedline have been upgraded on the 146.820 repeater and early tests seem to indicate its working much better! Please do your best to use it for day to day traffic this week and in the coming weeks, report any deficiencies to the technical committee members. There will still be a few more tweaks done to the repeater in the coming days to peak the duplexers and make sure its up to snuff.

For the hams amongst us (hi hi..) the antenna data sheet

145.670 Packet Node is active

FYI the Olmsted 145.670 packet node is operational on simplex 145.670, 1200 baud AFSK at 80 watts. The nodes ID is   “MNRST“. 

W0STV is working on an update on what other nodes it has heard and can connect to in the tri-state area. 
If you want to learn more about how to do keyboard to keyboard packet network communications  there are many youtube videos on the subject to get you up and running. When we had the system before you could contact Fargo, Duluth, and the Twin Cities.

Note: The MNRST node is unable to connect to the current nearest node WIWASH, with a vertical antenna. It is 79 miles north of Rochester.
When WIBAYC node comes on line that will be a 40 mile distance to link to. Will keep you updated on this progression. 

Winlink node – 145.010

The Winlink node is now back on 145.010.

This W0STV-10 winlink node is operated by W0STV. It had changed frequency to 145.010 in order to make 145.670 available to the statewide packet network. This network is poised to return to Rochester, linking us keyboard-to-keyboard to stations in the Twin Cities area.

Please continue to test and pass e-mail traffic via this node! Jason, KM4ACK has some excellent tutorials on how to get up and running with very low cost portable hardware (including the computer!)

KAØMYG 443.700 MHz Fusion Repeater

The KA0MYG 443.700 MHz repeater is owned and operated by John Dalin, KA0MYG. The repeater is located in downtown Rochester at 100 feet AGL. The repeater output is 20 watts and covers the downtown and central areas of Rochester.

This Fusion repeater supports standard FM analog voice and Fusion digital voice, however, the analog users will not be able to communicate with the digital users. Digital and analog users cannot be transmitting through the repeater at the same time. Since the digial and analog users share a common frequency, analog users should set a CTCSS tone of 100.0 Hz to filter out digital transmissions from Fusion users. 

This repeater will be up for general use until at least March 2017.

WØMXW 443.850 MHz D-Star Repeater

The WØMXW D-Star repeater, owned by the RARC club, is located at the top of the Mayo Clinic next to the 146.625 repeater.  It supports D-Star digital voice, slow speed data, and DPRS.  Analog FM voice cannot be used with this repeater.

The repeater offers both local digital and connection to talk groups, called Reflectors, through an internet gateway.  Ham radio operators with D-Star equipment can use the local repeater function, but in order to use the gateway and talk on the Reflectors, it is necessary to register with the D-Star system.  This registration helps to ensure that only ham radio operators are using the gateway.

D-PRS information is routed to the internet and out on 144.390 as well.
