Indiana Repeaters
📻 Browse the Indiana Repeater Directory — a searchable, filterable map and table of repeaters by county, frequency, mode, and tone.
A repeater is an automated station, usually on a tall tower or building, that receives your signal on one frequency and simultaneously re-transmits it on another. Because it sits up high and runs more power than a handheld, a single repeater can extend the range of a small radio from a few miles to dozens of miles. To use one you need to know three things: the output frequency, the offset (how far above or below that the repeater listens for your transmission, commonly ±600 kHz on 2 meters and ±5 MHz on 70 cm), and usually a PL / CTCSS tone (a sub-audible tone your radio must send to open the repeater's receiver).
Repeaters move, change tones, and go on and off the air constantly, so the best source is always a live, community-maintained database rather than a static list. For Indiana, that source is RepeaterBook.
New to offsets and tones? Start here
If terms like offset, CTCSS, PL, or DCS are new to you, these plain-English explainers walk through exactly what each setting does and why your radio needs it to open a repeater:
- HamStudy HamBook – Repeater Operation (offsets & CTCSS table)
- Silvercreek ARA – CTCSS / PL tones explained
Once you understand the settings, see our digital modes guide for how DMR, D-STAR, Fusion, and P25 differ on the air.
Find every Indiana repeater on RepeaterBook
RepeaterBook is the go-to, always-current directory of amateur repeaters. Browse the full statewide listing here:
RepeaterBook – Indiana statewide repeater listing
Every county page on this site also includes a RepeaterBook link filtered to that specific county, so you can quickly see what is on the air near you. Start from the county map and pick your county.
Other repeater directories & coordination
RepeaterBook is the easiest starting point, but several other community-maintained directories and the state coordinator are worth knowing:
- RFinder – the Worldwide Repeater Directory — a subscription database that integrates with many radios and programming tools.
- Artsci Publishing Repeater Database — a long-running, daily-updated repeater directory you can search by state or city.
- Indiana Repeater Council (IRC) — the volunteer body that coordinates repeater pairs in Indiana to keep them from interfering; the authoritative source for who is coordinated on which frequency.
Modes you'll find in Indiana
| Mode | What it is |
|---|---|
| FM (analog) | The traditional analog voice mode that the large majority of Indiana repeaters still use, and the easiest place for a new operator to start. |
| DMR | Digital Mobile Radio, a TDMA digital voice standard that splits one channel into two time slots and uses "talkgroups" to route audio across networked repeaters. |
| D-STAR | An Icom-developed digital voice and data mode that connects repeaters and hotspots over the internet through "reflectors." |
| Yaesu System Fusion (C4FM) | Yaesu's digital voice standard, often paired with WIRES-X linking, on repeaters that frequently auto-switch between digital and analog FM. |
| P25 | APCO Project 25, a digital standard shared with public-safety radio and used by a smaller set of amateur repeaters and networks in Indiana. |
Major Indiana linked systems & networks
Several wide-area systems link many repeaters together so that a conversation started in one part of the state can be heard across a large region. The major verified ones are below.
| System | Coverage & notes |
|---|---|
| W9WIN Linked Repeater System | A large analog-and-digital linked system covering roughly a third of Indiana — about three dozen counties — centered on the Indianapolis area and southern Indiana. Includes VHF, UHF, a 10-meter repeater, EchoLink, and a live internet audio feed. |
| Indiana Digital Ham Radio (IDHR) | A clearinghouse of Indiana digital-mode information — DMR, D-STAR, Fusion, and P25 — including a statewide DMR repeater list across all networks, hotspot help, and talkgroup details. |
| Crossroads DMR Network | An Indiana-based DMR network (documented on the IDHR site) linking repeaters in cities such as Fort Wayne, Elkhart, Muncie, New Castle, Noblesville, Plymouth, and Shelbyville, with talkgroups bridged across its c-Bridge. |
| West Central Indiana Amateur Radio (WC9IN) | A linked group of full-time repeaters across west-central Indiana, spanning Benton, Tippecanoe, Cass, Clinton, Howard, Montgomery, and Fountain counties, with battery backup and Skywarn ties. |
Indiana also has active D-STAR and statewide DMR activity; the IDHR site above is the best starting point for the current list of digital repeaters and talkgroups statewide.
Indiana digital talkgroups & reflectors
Indiana Digital Ham Radio (IDHR) maintains mode-by-mode pages with the current statewide talkgroup, repeater, and reflector references:
- IDHR – Indiana DMR repeater list (all networks) — over 40 locations across BrandMeister, Crossroads, and Tri-State, with color codes, DMR IDs, and per-slot talkgroups.
- IDHR – Indiana D-STAR — statewide D-STAR repeater and reflector information.
- IDHR – Indiana Fusion (C4FM) — System Fusion / WIRES-X room references for the state.
Digital & linking networks behind the repeaters
Many Indiana digital repeaters and personal hotspots connect to larger networks. These dashboards let you watch live activity, look up nodes, and find the right talkgroup or reflector:
| Network | What it is & Indiana use |
|---|---|
| BrandMeister | The most widely used DMR network. The statewide Indiana talkgroup is 3118 — that link shows who has been heard on it most recently. |
| AllStarLink | A VoIP network linking analog repeaters, remote bases, and hotspots by node number; several Indiana repeaters use it for linking. |
| EchoLink node lookup | A live list of every logged-in EchoLink station and repeater node worldwide — search a callsign or node number to confirm an Indiana link is on the air before you connect. |
Get connected locally
The fastest way to learn which repeaters are actually in use near you is to join a club — members can tell you the local "watering hole" frequencies and tones. Browse the clubs directory or pick your county from the county map — each county page links straight to its RepeaterBook listing.
Repeaters are also where most local nets meet, so checking into a net is one of the fastest ways to confirm a repeater is working and to meet the operators who maintain it. For more on the digital modes those repeaters carry, see the digital modes guide.
