RepeaterBook is a free, worldwide resource for amateur radio operators.

Our site provides comprehensive information on repeaters, ham radio clubs, and other topics of interest to the amateur radio community.

While we strive to ensure the accuracy of our data, we rely heavily on input from users and local admins to keep the information up to date. Your contributions help us maintain the quality and reliability of this valuable resource.

We also work with frequency coordinators. If you are a frequency coordinator and interested in partnering, please contact us.

RepeaterBook is not an official listing from any repeater coordination authority. We do not coordinate repeaters and hold no authority in that regard. However, some coordination entities voluntarily share publicly available data with us to help improve the directory.

Importantly, RepeaterBook is the official source of repeater data for the ARRL (American Radio Relay League), helping ensure our database supports national amateur radio initiatives.

No, registration is not required to browse RepeaterBook. You're free to explore the site and access most features without creating an account.

However, registering unlocks additional tools and conveniences—such as the ability to generate export files for programming your radio, create custom printable repeater lists, and save personalized settings.

No, registration and use of RepeaterBook are completely free.

However, it does take time and money to operate and maintain a global resource like this. If you’d like to support the project and help fund ongoing development, please consider subscribing to RepeaterBook Plus. Your support helps keep the site running and free for everyone.

Yes. RepeaterBook is a community resource for licensed amateur radio and GMRS operators. All registered users must have a valid, government-issued call sign for one of these services.

Amateur radio is built on openness and accountability—we use our call signs on the air, and they’re publicly searchable. Maintaining that same level of transparency on RepeaterBook helps keep the community safe and free of abuse. Unfortunately, anonymous users are often the source of interference or misuse, and we actively discourage that behavior.

If you’re interested in amateur radio or GMRS but don’t yet have a call sign, you’re absolutely welcome to explore the site! However, you won’t be able to register or access features reserved for licensed operators, such as submitting repeaters, making edits, or exporting programming files.

Please note: The site administrator reserves the right to reject or revoke memberships at any time, with or without notice.

The administrator reserves the right to reject or cancel memberships to this site at any time, with or without cause or notice.

If you hold both a U.S. Amateur Radio call sign and a GMRS call sign, please register using only your Amateur Radio call sign.

Do not include any spaces, slashes, or suffixes (e.g., avoid using formats like KX9ABC /G or KX9ABC-A). Just enter your call sign exactly as issued—for example, KX9ABC.

Keeping call signs standardized helps ensure that your account works correctly across all RepeaterBook features.

RepeaterBook compiles repeater data from a variety of trusted sources, including user contributions, repeater owners, coordination councils, and public records.

We are proud to be the official source of repeater data for the ARRL (American Radio Relay League), and we work directly with many frequency coordination organizations that provide timely and accurate data for their regions.

In addition, amateur radio operators around the world help keep the database current by submitting corrections, updates, and new repeater listings. Each submission is reviewed by a local or regional admin before being published. Most updates are processed within 48 hours, though it may occasionally take longer. Our apps are typically updated every two weeks to include the latest data.

Keep in mind that in the U.S., there is no central government registry for repeaters—reporting is not mandatory, and some systems are never officially coordinated. That makes community input essential. Your submissions and corrections are a key part of keeping RepeaterBook reliable and useful for all operators.

Everyone on our team is a volunteer, and we deeply appreciate your help and patience as we continue improving the site.

The repeater database is updated constantly, all day, every day.

We update the apps about every two weeks.

We try not to claim accuracy and allow you to judge for yourself. It is challenging to be 100% accurate all the time. Repeaters come and go, and data sources and updates are limited. We depend on those with knowledge of the repeaters to submit the data. We also post who made the changes and what they changed so you can judge the accuracy yourself. Obviously, timely updates from repeater owners and trustees would be considered the most trustworthy data.

We also obtain some data by watching coordination council web sites. However, some are better than others about sharing and updating information via the Web. We appreciate those councils that have taken a proactive role in assisting us with data gathering.

We also look for other sources of information beyond what is available through coordinating councils. We search the Web for repeater Web sites, contact repeater users and trustees directly, test repeaters, and rely on you to assist with information verification.

When we add a repeater to the RepeaterBook database, we go beyond the basics. Our team and volunteers conduct detailed research—often searching across the Internet and club websites for publicly available details about the repeater.

Many repeater sponsors and clubs share valuable information online, such as coverage areas, access tones, net schedules, usage guidelines, and technical features. We gather and include that information to make each listing as informative and helpful as possible.

In addition to our own research, we rely heavily on the amateur radio community. Users are encouraged to submit updates and corrections when they spot missing or outdated information. These submissions are reviewed by our regional admins, who help ensure the accuracy of each listing.

We’re committed to offering the most comprehensive and up-to-date repeater directory available, and your participation plays a vital role in making that possible.

RepeaterBook exists to provide a free, open-access directory of repeater information for the benefit of the amateur radio community. Our mission aligns with the spirit of amateur radio as a public service: helping licensed operators connect, communicate, and explore the hobby with confidence.

By sharing your repeater’s information, you contribute to a reliable, centralized resource that serves:

• New operators looking for ways to get active in the hobby
• Travelers who rely on accurate repeater data to stay connected on the road
• Emergency communicators who may need quick access to regional repeater systems
• Fellow hams who want to socialize, test equipment, or learn more about their area

We never charge for access to our site, and we make every effort to keep the data accurate and current. Many repeater owners want their systems to be used and appreciated—listing your repeater helps promote its availability, features, and value to the community.

If your repeater is not open for general use, just let us know—we can mark it as closed, which respectfully signals to other operators that access is limited.

We hope you'll consider contributing your repeater’s information to help support a stronger, more connected ham radio community.

In most cases, no—a repeater does not need to be formally coordinated to be listed on RepeaterBook.

However, we do have agreements with certain regional coordination authorities. In these areas, specific data must be provided directly by the coordination group. If you submit a request to add a repeater in one of these regions, your request may be placed on hold until the repeater is officially coordinated and the data is released to us.

These agreements help ensure the accuracy and legitimacy of listings, as the data from coordination councils is typically vetted and up-to-date. This process helps us maintain the quality and reliability of the RepeaterBook database while respecting the work of coordination groups.

We’re happy to list your repeater as closed or private, and we can include a note in the comments section to inform potential users of its access restrictions. For added privacy, we will also suppress sensitive details such as PL tones, exact coordinates, access codes, and certain features.

However, if your goal is to completely “hide” your repeater from potential jammers or unauthorized users, removing it from RepeaterBook is unlikely to achieve that. Other online and printed directories often list closed or private systems as well, and modern scanning equipment can easily detect repeaters regardless of whether they’re published.

There are a few important reasons why we generally do not delete listings outright:

• Frequency coordination visibility: Our listings help other repeater owners and prospective builders identify existing activity on a given frequency or location, which can help prevent unintentional interference.
• Troubleshooting interference: When repeater conflicts occur, having even a basic public record can assist with identifying potential interference sources and resolving issues.
• Transparency is better than secrecy: In our experience, trying to hide a repeater often draws more attention from malicious operators. A visible, clearly marked “closed” listing typically discourages misuse more effectively than total omission.

We also understand that some repeater owners request their coordination authority not to publish certain details—yet the repeater still appears on RepeaterBook. In such cases, please know: your coordination authority is not responsible for this. Our data often comes from multiple independent sources, including public club websites and user submissions.

And finally, please don’t ask us to remove your repeater if you’ve already published its details on your own website—yes, that does happen!

Many of the volunteers who contribute to RepeaterBook are repeater owners themselves, so we understand that each operator has a different comfort level when it comes to sharing information about their systems.

As a courtesy, we’re happy to obscure or withhold certain sensitive details from public view upon request—such as:

• Precise GPS coordinates
• Micro-location landmarks
• PL tones
• Advanced feature settings or linking details

However, we will not obscure the following core information, which we believe is essential to the public and amateur radio community:

• Frequency
• City or nearest city
• County and state
• Operational status and usage rights
• Publicly available contact information or website

RepeaterBook’s mission is to support a transparent and accurate resource for the amateur radio community. Amateur radio operates on public spectrum, and repeater systems—by nature—are publicly accessible and detectable. While we respect your concerns, the general public has a legitimate interest in knowing what is operating on shared frequencies.

We occasionally receive strongly worded or combative demands to remove or obscure more information than our policy allows. Please understand that the First Amendment protects the right to publish information that is publicly available, including repeater locations and technical parameters. That said, we’re much more inclined to accommodate requests that are polite and respectful. We’re happy to work with you—just ask kindly!

To request a change to your listing, please contact us or use the update form available on your repeater’s detail page.

There are a couple of possible reasons, but the most common one is related to how the app works compared to the website.

The RepeaterBook app is not live-synced with the online database. This is intentional—it allows the app to function offline, which is especially useful in emergencies when Internet access may not be available.

Instead, the app contains a snapshot of the database that is updated approximately every two weeks. If your repeater was added or updated on the website after the most recent app update, it won’t appear in the app until the next release.

To check the version of your app:

1. Tap the menu (hamburger icon) in the top-left corner.
2. Look under the RepeaterBook logo for a version number formatted like 2025.04.01.

This number represents the year, month, and day the app was last updated.

If your repeater was added after that date, you’ll see it in the next update. Updates aren’t fully automated, so they may occasionally be a few days early or late.

To ensure you get the latest data, always keep your app up to date via the App Store or Google Play.

Yes, we do.

Absolutely! RepeaterBook is a volunteer-driven project, and we depend on the amateur radio community to help keep it accurate, up to date, and growing.

There are several ways you can contribute:

• We’re always looking for state and regional admins to help collect, verify, and maintain repeater data.
• Even if you're not an admin, you can still help by submitting corrections, updates, or new listings whenever you spot something missing or incorrect.
• It's quick and easy to add or edit repeaters directly from the site.

Every bit of help makes a difference—and we greatly appreciate your time and effort in supporting the ham radio community.

Great! Send us the information. Share it with everyone. The only way to make this site the most complete and up-to-date site on repeaters, nets, and clubs on the Web is for users to send us updated information.

We want the same thing everyone else wants…an accurate database to locate repeaters with. We try to do what we can to gather and validate information, but this is very hard. We welcome clean data from our users, but please know that the data we post cannot be guaranteed. We are sorry for that.

We also will not purchase information from sources who would seek to sell it to us for profit. This is a free site, and we simply can't afford to purchase data from local coordination councils.

As a note, it is somewhat baffling to us when we see the occasional post on a forum somewhere about Repeaterbook listings not being accurate or missing your favorite repeater. It probably took more time to rant about that, and then it would have to send us the update. Some areas are extremely accurate, and others not so much. This is directly proportional to the enthusiasm of the hams in that area to contribute to the site.

For the number of posts that we see complaining about the data, there are 10 more that rave about it.

First, search for the repeater in the database through the state or province it should be located in. If the search results do not include the repeater, select the 'New Repeater' link in the blue menu bar near the page's top.

A notification of the request will add the repeater to the database. You will be notified when this happens. Most of the time, updates are completed within 48 hours.

Admins are assigned a state or province, and they are generally responsible for the database information about that area. They will research to locate repeaters and update information, handle requests from site visitors, and review submissions.

Admins must be Ham radio operators with some knowledge of repeater operation (repeater owners preferred), some affinity to some basic web programming, and attention to detail.

The time commitment is not very high. There is some front-end work getting the data entered and updated, but ongoing maintenance is low. The typical admin can spend just 15 minutes per week handling requests and doing some light research. Occasionally, more time is required for the bi-annual data reviews.

RepeaterBook data exports have been certified by CHIRP, RT Systems, and G4HFQ. The recommended method for exporting the data is to use the corresponding Export menu option. This will create a file that you can import directly into the software.

The CHIRP and RT Systems software itself has an option to download directly from Repeaterbook.com.

You must be registered and logged on to access the Export menus.

Yes. You must be registered and logged in to see the Export option on the menu.

First, search for the repeater listing you want. You should see 'Export' on the menu. Choose 'CSV' as that file type can be opened by Excel.

Repeaterbook.com contains data on repeaters that operate on analog, digital, or both emission types. Not all radios can decode digital transmissions, and not all programming software programs are capable of programming radios that can decode digital signals (i.e., CHIRP). Using CHIRP as an example, CHIRP is not known to have the capability to program any DMR or D-STAR radios. For this reason, if the user attempts to download a list of repeaters where some are digital-only, they will be excluded from the CHIRP export to eliminate the need to weed these repeaters out of the list before programming a non-digital radio. If CHIRP later is capable of programming a digital radio, these repeaters can be added back in the export.

To export data to the Kenwood MCP-4A programming software, you can use the TravelPlus .tpe format. The MCP-4A export is not compatible with the Kenwood software.

If you are trying to program an IC-7100 using CS7100 cloning software for D-Star repeaters, we would like to provide this export. We would need a sample of a file that can be uploaded to this radio to create a similarly-structured file.

The TravelPlus tpe format is a file format specifically designed to export to radio programming software. All programming software applications should be able to accept this file format as produced by the TravelPlus software.

The TravelPlus tpe file export directly from TravelPlus will not work in CHIRP (as of the 20140124 daily build). The tpe file from RepeaterBook has been modified to allow the file to work.

You may find that exporting a tpe file from TravelPlus and importing into TravelPlus may produce errors. You should have a better experience with the RepeaterBook version of the tpe format. However, this formatting change does come at a cost as the data is more generic. We are working with CHIRP to correct errors to return the RepeaterBook tpe export file to the same format the TravelPlus software produces.

Many of us are repeater owners, and we always cringe when we hear about repeaters that are damaged or vandalized. We know that outdoor enthusiasts come across repeaters and cause so much havoc for their own fun.

We really hope that Ham Radio operators are above using RepeaterBook to locate a repeater and inflict damage upon it. However, we know that it certainly can happen, but are we liable? The short answer is no.

We understand your concerns and want to work with you but take a deep breath first. When we receive this request, invariably, some right to privacy or copyright is claimed. An assertion that permission has not been granted to publish the data on this website is prohibited.

Most people who make such a claim actually do not know how copyright and the fair use doctrine work. If they did, they would probably not make an uninformed legal argument. But because this method is employed from time to time, we opted to do some research for you.

Privacy Argument

Consider for a moment that the repeater listing on RepeaterBook was similar to your home address being published on the Internet. It is nearly impossible to prevent as there are many website parsing data from multiple government and commercial entities publishing your information. To keep your address from print in the local phone directory, you must initiate a request to your local phone service provider. Notice they never ask for your permission to print your address, but in fact, charge you to obscure it. They may even offset their own costs by reselling the information to others.

Your address information may sit in databases connected to tax records, property records, mortgage houses, voting records, DMV, financial institutions, court records, employers, cell phone providers, and other commercial entities. All making your address, email, and phone number available without your permission. (especially property records and court documents), utility companies and credit card companies. There are no laws prohibiting these data collectors from publishing this information about you without your permission.

Many people misunderstand what their “right to privacy” really is. While companies may be required to safeguard Personal Identifiable Information (PII) to protect your identity, your home address is not protected. Though many companies maintain privacy policies as a service to their customers, they are not legally required to do so. There are many laws restricting the government from indiscriminately collecting data about you, but not private individuals or companies. For more information about US Privacy laws, try http://www.rbs2.com/privacy.htm.

How does this apply to a repeater? A repeater is not a person and has no privacy rights at all. Where it is, the mode it is using, frequency and PL tones used, call sign, DTMF commands, etc., are not protected under any law. The FCC even prohibits amateur radio operators from using any sort of encryption to hide this information. Asserting privacy concerns to request the removal of a repeater entry is without merit and we are not required to act on it on that basis. The repeater is either transmitting or receiving information on the publicly available radio spectrum. The only spectrum with any type of protection is cellular.

Copyright and Permission Required Argument

Most websites put Copyright notices on the footers of their pages. What is the legal effect of doing so?

As far as copyright law and a database like this, many people believe incorrectly that they have some protection from their repeater's information from being published on RepeaterBook. Please take a moment to study Copyright protections on the US Copyright Office http://www.copyright.gov/ website.

Specifically not protected is fact. Repeater data on this site is comprised of facts. The operating frequency, PL, offset, location, call sign, etc., is all fact. We do not violate copyright by copying or displaying elements of design that can be copyrighted. We don't reuse maps, charts, or images from a site without permission. Our formatting of the information is not borrowed from another site and is unique to our style. A book that is a collection of facts can still be copyrighted. However, the facts contained within are not protected and can be re-published elsewhere. The protection is the book's format and the method for expressing the facts. Sentence structure, for example.

A specific example would be data published on a website controlled by the operator of a repeater. There is no legal protection of the information posted on the repeater that is factual in nature. Permission is not required to copy this data and enter it into the RepeaterBook database. No set of words could be placed on the website or printed material to prevent factual information from being recorded and republished elsewhere. Period. If you are still confused about this, please return to the US Copyright Office link above.

We would rather work with you and not against you. We just want you to get over the idea that you have legal leverage when approaching us to remove information. We have no legal requirement to remove a repeater listing. Yelling, screaming, or threatening anything (including lawsuits) in an attempt to remove your repeater listing will be ignored. We prefer pleasant conversations with grown-ups who can discourse in a friendly manner.

We would like to point out that we would like to represent everything good about amateur radio. We do not wish to be argumentative about these points or debate them with you. We would prefer to embrace you as a fellow ham and work together in a spirit of cooperation to come to a mutually acceptable arrangement. While other repeater listing repositories attempt to make money on their products, there is no requirement on this site to pay money to receive any information. We are simply a collection point for publicly available information. We believe because of our operating practices, you may be most willing to share your information.

We should also note that requests to remove data outside of PL tones, locations, and coordinates from the site are actually pretty rare.

Case law can be found on this regarding websites that publish police officers' home addresses and abortion doctors. Recently, a three-judge panel of the 9th U.S. Circuit Court of Appeals unanimously said the activists could be held liable only if the material authorized or directly threatened violence. A Supreme Court ruling said a threat must be explicit and likely to cause “imminent lawless action.” Their right to publish this information is protected under the First Amendment of the U.S. Constitution. Even when common sense tells you that the posting of the information is to allow for the information to get to someone who would harm the individual, it is still protected. The poster of the information is not responsible for the actions of another individual. This all changes, however, if the poster encourages others to inflict harm upon the individual.

Since the operators of this site do not wish harm to come to any repeater, in fact, the opposite, the site and its operators cannot be held liable for any actions taken by a third party with information gleaned from the site.

We have over 30,000 repeaters in the database, and that would be quite the chore. Considering the options, we thought it would be much too cumbersome and expensive to get consent from a repeater owner before posting any data about a repeater. It would be a non-starter.

As many of us are repeater owners or board members of large clubs with repeaters, we decided that such a mailing would be expensive, overwhelming, difficult, and likely fruitless. If every administrator of a Web site attempted to gain the permission of a repeater owner, repeater owners would be so tired of receiving requests that they would likely ignore them.

Cost is also a major factor. We figured the cost would be about $1.00 per mailing. Currently, we service more than 21,000 repeaters. For a free site, that cost is overwhelming.

Finally, there are no legal or moral requirements to request permission to publish facts, especially when they are generally available from other sources. So, for now, we will continue to gather information as we do and pledge to work with repeater owners' concerns as they arise.

Yes, we do. You can obtain it at Press Kit here.

Yes, interviews can be arranged. Please use the contact form to reach the site admin/owner.
