Indiana on BrandMeister DMR

BrandMeister is the largest of the internet-linked DMR networks, and most Indiana DMR repeaters are connected to it. Its dashboard publishes every device on the network, worldwide, with no key required — which makes it tempting to reprint and a bad idea to reprint carelessly. This page is the part of it worth reprinting: Indiana's talkgroups, and every Indiana repeater on the network — each one marked with whether a second record agrees with it, or whether BrandMeister is the only place it appears.

Indiana talkgroups

A talkgroup is the DMR equivalent of a channel: you key up on one and everybody subscribed to it hears you, wherever their repeater is. Indiana's talkgroups live in the 3118x block, plus 3118 itself for the statewide one. These are the names BrandMeister carries for them, exactly as published.

The whole 3118x range was checked, not just the ones already known here; the numbers missing from the table are not allocated on BrandMeister. A name is repeated as BrandMeister writes it — where an abbreviation is not expanded above, that is because nothing was found that says what it stands for, and a plausible guess would read exactly like a fact. Note also that talkgroup 8710, which you will see quoted for the Crossroads statewide net, is not a BrandMeister talkgroup at all — the number belongs to a different network. On BrandMeister the bridge is 31189.

Indiana nets lists the nets that meet on these, including the statewide DMR information net on 3118.

Indiana repeaters on the network

19 Indiana repeaters are connected to BrandMeister. 10 of them also appear in a record this site already holds, on call sign and output frequency both — two independent sources naming the same machine. The other 9 are on BrandMeister and nowhere else we have; they are marked as such in the Source column and are worth trying, not withheld.

Frequencies in MHz. CC is the DMR color code, which your radio must match. Power and antenna height are the sysop's own entry in BrandMeister and nothing checks them — see below. Checked 2026-10-31.

What “last on the network” actually means

That date is the last time the repeater talked to a BrandMeister master server. It is network presence, self-reported by the device, and it is not evidence that anything is transmitting on RF. A repeater can hold a perfectly healthy internet link with a failed amplifier behind it, and a repeater in daily local use can be missing from BrandMeister entirely because its owner never connected it — plenty of Indiana DMR machines run on other networks or on none.

This is the same distinction repeater coordination draws. A coordination record answers who holds the pair. A BrandMeister entry answers who is logged in. Neither answers what will I hear tonight — for that, listen, ask a local club, or check into a net.

Why the numbers on this page are small

BrandMeister lists about 32,924 devices worldwide. Cutting that down to 19 Indiana repeaters took four filters, and each one is there for a specific reason. Only the first three remove anything; the fourth decides what a row is labeled.

1. Most of what is in there is somebody's house. The great majority of DMR devices are personal hotspots — a matchbox-sized board on a shelf that puts one operator on the network. A hotspot's row is a licensed operator's call sign sitting next to the coordinates of the room they are sitting in. None of them are on this page, in the published data, on a map, or in any count you could work backwards from. Where a device's nature was uncertain it was left out, on the principle that a missing repeater costs a reader a lookup and a wrong inclusion costs somebody their address.
2. A bounding box is not a state. A rectangle drawn around Indiana also catches Olney and Danville in Illinois and Big Bone in Kentucky. Indiana here is decided by testing each point against the actual county boundaries — the same US Census outlines the map on this site is drawn from — which also says which county a repeater is in.
3. The power and height fields are fiction often enough not to be trusted. They are typed in by the owner and nothing validates them; the feed contains devices claiming tens of watts from an antenna zero feet above the ground. They are shown above as reported and are used as evidence of nothing. What is structurally reliable is the frequency pair: a device transmitting and receiving on the same frequency is simplex and is not a repeater, and a genuine Indiana repeater sits on the separation the state's frequency coordinator publishes for its band.
4. Two records agreeing is better than one. One is still worth having. The last step compares each surviving device against this site's own repeater list. 10 matched on call sign and frequency both, and the Source column says so. 9 did not: duplex machines on commercial repeater hardware, inside Indiana, on a coordinator-published pair, but named in no other list we hold. They are printed and marked BrandMeister only rather than withheld. A repeater that is missing from every other directory is precisely the one a reader cannot find anywhere else, and the honest way to report a single-source fact is to say it came from one source — not to keep it. Treat such a row as a lead worth trying: the frequency pair and color code come from the machine's own network registration, while the town is the sysop's typed entry and may be approximate. Tell us if you run one, and it moves into the confirmed column.

Getting on DMR in Indiana

• Set up a hotspot — if you are not in range of a DMR repeater, a hotspot puts you on these talkgroups from home.
• Digital modes — how DMR compares to D-STAR, System Fusion and the rest.
• SKYWARN spotter training — talkgroup 31183 above is Indiana's weather operations talkgroup, and the class is what it exists to carry.
• BrandMeister dashboard — the network's own site, where the live picture and the bulk data are.

Device and talkgroup records on this page come from the BrandMeister DMR Network and are used with credit. BrandMeister publishes no terms of use, license or copyright notice for its API, and silence is not permission — so this site does here what it does with the Indiana Repeater Council: it publishes the repeater rows, each marked confirmed or unconfirmed, and the talkgroup list, with a link back, and does not redistribute the whole database. For the bulk data, go to BrandMeister, where it is free. What is published here — the repeater rows, the talkgroup list and the method — is dmrIndiana.json on the open data page.
