one conversation across seven digital modes: D-STAR, DMR, Fusion, P25, NXDN, M17, and AllStar.
The UtahDRN (Utah Digital Radio Network) multi-mode bridge ties seven digital voice modes onto three shared modules. A station calling on any mode is heard by everyone connected to the same module; so a D-STAR user on REF029 C, a DMR user on talkgroup 314901, and a Fusion user on YSF 31491 are all in the same room. This is how REF029, the Utah D-STAR reflector, reaches the wider Utah digital network, and it's why the NUTS Sunday net can be checked into from any mode.
This matters in Utah because native D-STAR RF activity is minimal. On its own a Utah D-STAR repeater can be very quiet, but linked to REF029 it carries everyone on the bridge, and DMR has by far the largest Utah user base of the bridged modes. So the bridge is what turns a sleepy D-STAR repeater into a busy channel: most of the traffic you hear arrives over DMR and the other modes, not D-STAR.
Pick a row for your mode, then a column for the module you want. Everything in that column is the same conversation.
| Mode | Utah 00 · mod B | Utah 01 · mod C | Utah 05 · mod D |
|---|---|---|---|
| D-STAR | REF029 B | REF029 C | REF029 D |
| DMR (talkgroup) | 314900 | 314901 | 314905 |
| Fusion (YSF) | 31490 | 31491 | 31495 |
| Fusion (YSF VW) | 31590 | 31591 | 31595 |
| P25 | 31490 | 31491 | 31495 |
| NXDN | 31490 | 31491 | 31495 |
| M17 | UT0 B | UT0 C | UT0 D |
| AllStar (ASL) | 29630 | 29631 | 29635 |
Module C / Utah 01 / REF029 C is the busiest; it's where the NUTS Sunday net and most day-to-day Utah traffic live. Start there.
REF029 and pick the module, e.g. URCALL REF029CL for module C. See the reflectors page.314901 for module C) on a Utah DMR repeater or your hotspot.31491); use the VW number for wide-mode voice.31491 for module C).UT0 and select the module (B / C / D).29631 for module C).Callsigns don't fully survive the bridge in one direction. D-STAR transmissions carry their originating callsign across to DMR (and the other modes) just fine. Traffic going the other way (DMR, Fusion, P25, NXDN, M17, or AllStar → D-STAR) shows up on D-STAR radios under a single placeholder callsign rather than the actual speaker's call.
This is a constraint of the REF reflector network: REF only accepts traffic from callsigns that have been registered on the D-STAR trust network. Rather than dropping every DMR user who has not registered for D-STAR, the bridge substitutes one known-registered callsign for everything coming inbound, so all the traffic gets through. The trade-off is that you cannot tell from the D-STAR side who is actually talking; you have to listen to verbal identification of their callsign.
