Minneapolis 2 – 147.225

The “Minneapolis 2” repeater on 147.225 is mixed-mode (analog and digital) and is equipped with an S-Com 7330, Raytheon SNV-12 voter, and Allstar node for analog call processing and linking, and an MMDVM with Yaesu System Fusion (YSF),DMR, and P25 enabled. The YSF module is internet connected to the YSF Reflector network and DMR is connected to Brandmeister. The P25 module can be linked to a reflector by demand.

Specifications:

  • Antenna: DB-224-E at 290 feet, Andrew LDF7-50A transmission line.
  • Output: 90 watts
  • RF deck: Harris Mastr III repeater
  • Battery Backup
  • Auxiliary receivers located in Salina and Lincoln (when using analog with 162.2 Hz tone)

Analog Setup:

  • Local users should program this repeater into two different memory channels.
    • For normal K-Link use:
      • Frequency: 147.225
      • Offset: +
      • TSQ: 162.2 (prevents the “noise” of the YSF bitstream and allows monitoring K-Link via this repeater)
    • For local-only use:
      • Frequency: 147.225
      • Offset: +
      • TSQ: 123.0 (prevents the “noise” of the YSF bitstream and allows monitoring the local-only mode of this repeater)
  • Local traffic using tone 123.0 will over-ride K-Link network traffic and will temporarily drop the K-Link connection both ways for 20 seconds from the last local user transmission.
    • Any transmission on this repeater using tone 162.2 will instantly re-enable the K-Link connection.
  • K-Link audio on this repeater can be interrupted by a local digital user on this repeater for up to 60 seconds after their last transmission.

YSF Setup:

  1. Tune your radio to 147.225 with + offset
  2. Use DG-ID TX:00 and RX:00 (radios with old firmware should have Digital Squelch Code set to OFF)

That is the extent of the setup required to access the YSF mode. Additionally, here are some important points of interest:

  • This repeater is normally networked to the “US-KansasLink” YSF Reflector.
    • You can link to other reflectors by entering WiRES-X mode on your radio and selecting another reflector.
    • Please move it back to US-KansasLink when you are finished with your contact.
    • You don’t need to use WiRES-X mode if you plan to stay on KansasLink.
  • YSFReflectors are an open-source alternative to the official Yaesu WiRES-X network. You cannot access official WiRES-X nodes or rooms via this repeater.
  • Local and K-Link analog activity have higher priority than digital activity coming from the internet. If this repeater is busy with analog traffic you may switch to “Minneapolis 3” located at the same site.
  • Local digital users can “borrow” the repeater away from K-Link network traffic as long as the repeater is not being used locally on analog.
    • The “borrow” timer will hold off K-Link traffic for up to 60 seconds after the last local digital transmission.
    • The “borrow” timer will be cancelled and K-Link immediately re-enabled by any local transmission with tone 162.2.
  • When Minneapolis 2 and 3 are linked to US-KansasLink (they usually are), both repeaters are linked together (in YSF mode).
  • Our YSF Reflector is bridged to Brandmeister DMR talkgroup 31203. You must use DN mode to communicate with DMR users across the bridge. VW mode will not work. If you want your callsign to show up on DMR radios you will need to register your callsign with DMR-Marc.
  • US-KansasLink is not the same thing as K-Link and the two networks are not linked together.

DMR Setup:

  • Your codeplug will need one “channel” programmed for every talkgroup you intend to use. Your radio will have to be programmed with your unique DMR ID (obtained from the DMR-MARC website)
  • Each channel will have to be configured with:
    1. RX Freq: 147.225
    2. TX Freq: 147.825
    3. Color Code: 1
    4. The time slot you want to use (see below)
    5. The group ID you’d like to use (see below)
  • There are no static Brandmeister talkgroups assigned to either time slot.
  • You may dynamically access any Brandmeister talkgroup on either timeslot by keying PTT with the group selected.
    • Please don’t do this to “lurk” on a group or groups.
    • Dynamic groups remain active for 15 minutes after the last local transmission.
  • The DMR mode on this repeater is offered as a convenience to travelers and visitors with VHF-only gear to use while in our area. Regular local users should use Minneapolis 3 for DMR calls whenever possible.

P25 Setup:

  • Your codeplug will need to be programmed with your unique DMR ID number (obtained from the DMR-MARC registration site).
  • Program a channel with the following information:
    1. RX Freq: 147.225
    2. TX Freq: 147.825
    3. NAC: 293
    4. 12.5 KHz channel bandwidth
    5. “Astro Audio” or however you set digital audio mode
  • The repeater is not connected to a P25 reflector. It’s available for local calls only at the moment. Regular local users should use Minneapolis 3 for P25 calls whenever possible.
