Repeater Upgrade – 146.625

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.

Costs:

  • 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.

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 operated by W0STV has 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.

For Registration, see here: https://w0mxw.dstargateway.org/
