The Minneapolis repeater on 444.750 is digital only using an MMDVM with DMR and YSF digital modes enabled.
- The DMR mode is networked full-time to the KS-DMR Network.
- The System Fusion mode can be linked to YSFReflectors or FCS reflectors but is not linked by default.
- Antenna: DB-408 at 300 feet, Andrew AL7-50A transmission line.
- Output: 100 watts
- RF deck: Motorola MTR2000
- STM32-DVM-MTR2K by N0MJS
- Pi-Star software
- Power amplifier: Henry C200D30B
- Battery Backup
The mode priority setup is:
- System Fusion
- Your radio will have to be programmed with your unique DMR ID (obtained from the RadioID.net website)
- Each channel will have to be configured with:
- RX Freq: 444.750
- TX Freq: 449.750
- Color Code: 1
- The time slot and group contact ID of the group you want to use from the list below:
KS-DMR Repeater TGID tableTable showing the available talk group ID's on repeaters connected to the primary system.
|Voice for Linked Group||1||9|
|Subscriber to Subscriber calls (brief)||1||(Private radio ID)|
To access any of the available linked groups:
- Select the channel programmed with TS1:TG9.
- Go into your contact list, select the talkgroup (from the list below) you wish to link to and key PTT for two seconds with the desired linked group selected. When you unkey the link will be activated.
- When your radio display reverts back to S1:G9 you may begin talking.
- Note: The linked group ID’s are to be used for in-band signalling to trigger link activation, not to talk on. All voice traffic for linked groups happens on TS1:TG9.
- Please don’t do this to “lurk” on a group.
- Linked groups remain active for 30 minutes after the last local transmission, and only one linked group is available at a time.
- Please do not transmit voice on any TGID not listed above.
Here is a video that demonstrates contact-based linking.
KS-DMR Linkable Groups
- Tune your radio to 444.750 with + offset
- Use DG-ID TX:00 and RX:00 (radios with old firmware should have Digital Squelch Code set to OFF)
- In AMS mode, set any TSQ or DCS tone/code. This prevents you from hearing the DMR bitstream which cannot be decoded by a Fusion radio and allows you to scan this channel within a list of analog and Fusion repeaters.
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 not linked to any reflectors.
- You can link to other reflectors by entering WiRES-X mode on your radio and selecting your choice of reflector.
- Please un-link the node when you are finished using it.
- Don’t link to a reflector just to listen or “lurk”. If you link, talk on it.
- 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.
- If the repeater is busy with DMR traffic, do not transmit until the repeater is available.
- Please use only the DN voice mode. The VW mode does not work through the DMR cross-link and does not offer robust bit-error correction.
