§ 97.119 Station identification.
(a) Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station.
(b) The call sign must be transmitted with an emission authorized for the transmitting channel in one of the following ways:
(1) By a CW emission. When keyed by an automatic device used only for identification, the speed must not exceed 20 words per minute;
(2) By a phone emission in the English language. Use of a phonetic alphabet as an aid for correct station identification is encouraged;
(3) By a RTTY emission using a specified digital code when all or part of the communications are transmitted by a RTTY or data emission;
(4) By an image emission conforming to the applicable transmission standards, either color or monochrome, of § 73.682(a) of the FCC Rules when all or part of the communications are transmitted in the same image emission
(c) One or more indicators may be included with the call sign. Each indicator must be separated from the call sign by the slant mark (/) or by any suitable word that denotes the slant mark. If an indicator is self-assigned, it must be included before, after, or both before and after, the call sign. No self-assigned indicator may conflict with any other indicator specified by the FCC Rules or with any prefix assigned to another country.
(d) When transmitting in conjunction with an event of special significance, a station may substitute for its assigned call sign a special event call sign as shown for that station for that period of time on the common data base coordinated, maintained and disseminated by the special event call sign data base coordinators. Additionally, the station must transmit its assigned call sign at least once per hour during such transmissions.
(e) When the operator license class held by the control operator exceeds that of the station licensee, an indicator consisting of the call sign assigned to the control operator’s station must be included after the call sign.
(f) When the control operator is a person who is exercising the rights and privileges authorized by § 97.9(b) of this part, an indicator must be included after the call sign as follows:
(1) For a control operator who has requested a license modification from Novice Class to Technical Class: KT;
(2) For a control operator who has requested a license modification from Novice or Technician to General Class: AG;
(3) For a control operator who has requested a license modification from Novice, Technician, General, or Advanced Class to Amateur Extra Class: AE.
(g) When the station is transmitting under the authority of § 97.107 of this part, an indicator consisting of the appropriate letter-numeral designating the station location must be included before the call sign that was issued to the station by the country granting the license. For an amateur service license granted by the Government of Canada, however, the indicator must be included after the call sign. At least once during each intercommunication, the identification announcement must include the geographical location as nearly as possible by city and state, commonwealth or possession.

Good operating practices for Digital Mobile Radio (DMR) ensure efficient and effective communication while promoting a positive experience for all users. Here are some key practices specific to DMR:
- Familiarize Yourself with DMR Basics: Understand the fundamental principles of DMR, including how to program your radio, navigate talk groups, and use features like call routing and private calls.
- Program Your Radio Correctly: Take the time to properly program your DMR radio with the necessary frequencies, talk groups, and other settings. Ensure that you have the correct configuration for the repeaters and systems you plan to use.
- Choose the Right Talk Group: Use the appropriate talk group for your communication needs. Avoid causing unnecessary congestion on popular talk groups by choosing the most suitable one for your conversation.
- Listen Before Transmitting: Before transmitting, listen to ongoing conversations on the talk group to ensure that you are not interrupting or talking over other users. This helps maintain communication etiquette and prevents unnecessary disruptions.
- Identify Yourself Properly: When transmitting, use your call sign as required by regulations. This helps other operators identify you and promotes accountability and compliance with licensing requirements.
- Keep Transmissions Concise: Be brief and to the point when transmitting on DMR. Avoid unnecessary repetition or extended messages that can tie up the channel and inconvenience other users.
- Respect Time Slots and System Capacity: Understand how time slots work in DMR systems and avoid monopolizing a time slot with long transmissions. Respect the capacity of the system and be mindful of other users sharing the same resources.
- Avoid Kerchunking and Unnecessary Keying: Refrain from “kerchunking,” which involves keying up the repeater or talk group without transmitting any meaningful information. Similarly, avoid unnecessary keying that can cause interference or disrupt ongoing communications.
- Practice Courtesy and Etiquette: Be courteous and respectful to other users on the DMR network. Avoid using offensive language, engaging in disruptive behavior, or causing unnecessary interference.
- Stay Informed and Updated: Keep yourself informed about any changes or updates to DMR systems, including firmware updates for your radio and modifications to talk group configurations or repeater settings.
- Be Prepared for Emergencies: Familiarize yourself with emergency procedures and protocols for DMR communication. Be ready to assist in emergency situations and prioritize emergency traffic when necessary.
By adhering to these operating practices, DMR users can contribute to a positive and efficient communication environment, fostering collaboration and enjoyment within the DMR community.
Getting banned from a talk group on the BrandMeister network typically involves behavior that violates the rules and guidelines established by the talk group’s administrators or the network itself. Here are some common practices that could lead to being banned from a talk group:
- Disruptive Behavior: Engaging in disruptive behavior such as continuously interrupting conversations, playing music, making loud noises, or transmitting inappropriate content can lead to a ban.
- Violation of Network Policies: Any activity that violates the network’s policies, such as using the talk group for illegal activities, promoting hate speech, or transmitting prohibited content, can result in a ban.
- Excessive Kerchunking: Constantly keying up the talk group without transmitting any meaningful communication (kerchunking) can be considered disruptive and may lead to being banned.
- Failure to Follow Talk Group Guidelines: Not adhering to the specific rules and guidelines set by the talk group’s administrators, such as respecting designated topics or modes of operation, can result in disciplinary action.
- Harassment or Abuse: Harassing or verbally abusing other users on the talk group, including using offensive language, making personal attacks, or engaging in discriminatory behavior, can lead to a ban.
- Spamming or Flooding: Sending a large volume of unnecessary or irrelevant messages, often referred to as spamming or flooding, can disrupt communication and may result in being banned from the talk group.
- Impersonation: Pretending to be someone else or using someone else’s call sign without authorization is a serious offense and can lead to immediate banning from the talk group and potentially from the network.
- Repeated Violations: Continuously disregarding the rules and guidelines of the talk group despite warnings or previous disciplinary actions may ultimately result in being banned.
It’s important for users to familiarize themselves with the rules and guidelines of each talk group they participate in and to respect the administrators’ decisions regarding enforcement. Maintaining a positive and respectful environment benefits all users of the BrandMeister network.
What is the proper way to break in when a conversation is going on a talk group?
Say your call in between TX. You usually will be acknowledged and then you can join the conversation or make your call. Please try and only transmit your callsign and wait to let the next station talk and pass it to you next, this is common courtesy.
This handy operating aid contains four useful references including the UTC time conversion chart, the ITU phonetic alphabet, guidelines to using the RST System, communication procedures and good phone operating guidelines.
Voice | Code | Situation |
Go ahead | K | Used after calling CQ, or at the end of a transmission, to indicate any station is invited to transmit. |
Over | AR | Used after a call to a specific station, before the contact has been established. |
KN | Used at the end of any transmission when only the specific station contacted is invited to answer. | |
Stand by or wait | AS | A temporary interruption of the contact. |
Roger | R | Indicates a transmission has been received correctly and in full. |
Clear | SK | End of contact. SK is sent before the final identification. |
Leaving the air or closing the station | CL | Indicates that a station is going off the air, and will not listen or answer any further calls. CL is sent after the final identification. |

Chpt 6 – Communication With Other Hams
Having learned all that interesting material about rigs and electronics and radio waves, you know a lot about the technology of radio. In this chapter we turn to operating – how are contacts made and what does a contact consist of? We begin with the elements common to nearly every causual ham radio contact. Once you know these, you’ll learn how the ham bands are organized so that you know where to tune the radio. You’ll then discover how ham radio is conducted using repeaters and in the organized activities called “nets,” especially during emergencies. This chapter conludes with coverage of a few of ham radio’s many specialty activities. Clear your throat and get ready for the first contact!
This page is organized to support the Fifth Edition of the Ham Radio License Manual.
- Operating Procedures
–The most complete reference is the ARRL Operating Manual, now in its 10th edition. Online, you can find resources in the On The Air section of the ARRL website.
- Grid Square Locators
+The Maidenhead system of defining location by grid square is defined on the ARRL website, including a grid square calculator, and in this Wikipedia article. - Keeping a Log
+The popular AC6V website(maintained in memory of AC6V) keeps a long list of software for logging your contacts. The ARRL also maintains a database of contacts called Logbook Of the World. Many hams have their own QSL cards and exchange them either direct through the mail or via the international system of QSL bureaus.
- Band Plans, Privileges, and Beacons
+You’ll need to refer to the online amateur band plans and beacon lists. The Northern California DX Foundation’s system of HF beacons is also a great way to find out whether a band is open and to where! Explore the Reverse Beacon Net and DX Maps to see who is hearing and contacting whom on the different bands.
Here’s how to find out who the Frequency Coordinator is in your area.
And everyone needs a frequency chart of the ham bands! Here’s a chart showing the latest Technician privileges.
- Digital Repeaters
+The most-used digital repeater or relay protocols are:
- Internet Relay Linking Project (IRLP)
Echolink - D-STAR(Icom and Kenwood equipment)
- WIRES-II(part of System Fusion)
- Digital Mobile Radio
- Net Operating
+ You can locate nets using the ARRL’s Net Search service.
The organization and practices of the National Traffic System are the model for most net operating procedures.
A properly formatted radiogram can be seen here.
The ARRL’s FSD-218 is a handy single-page reference for traffic handling.
- Emergency Operation and Employee-Employer Relations
+ The FCC’s Part 97 rules (Part 97.113 – Prohibited Transmissions) control the use of Amateur Radio transmissions in support of your employer. Watch for notices of question pool and FCC rule changes. If you are a member of an emergency communications team, ask your leadership for information. The ARRL has prepared a set of guidelines on the subject and will update it as necessary.
- Emergency Communications or “Emcomm”
+ Part 97.407 of the FCC Rules covering RACES operation- Federal Emergency Management Agency (FEMA)
- ARRL On-line Emcomm Courses
- Batteries as Emergency Power Sources
+ As referenced in Chapter 5, Battery Universityis a great resource for information about the use and maintenance of batteries.
- DX-ing, Contesting, Awards, ARDFing, and Special Events
+ The ARRL’s Operating Manual is your best single source for information on these and other ham radio activities. Enjoy browsing the more than 3,000 different awards on K1BV’s web directory of ham radio award programs. For online information, go to the On The Air section.
For fun, check out the following websites and print references:
- The Complete DXer by Bob Locher W9KNI

- Amateur Radio Direction Finding (ARDF)
- WA7BNM’s Contest Calendar is the most complete online listing
- ARRL Contest Update– biweekly email newsletter, free to ARRL members
- National Contest Journal– bimonthly magazine on contesting
- Field Day is a great way to find out about many different types of operating – find a club’s Field Day location and check it out!
Amateur Satellites
+ The best place for comprehensive information on Amateur Radio satellites is the AMSAT organization that coordinates most amateur satellite information.
- Amateur Satellites– general information about communicating through the amateur satellites
- Amateur Radio on the ISS– learn all about contacting the International Space Station
- Earth-Moon-Earth or “Moonbounce“– information on this lengthiest of contacts and other interesting operating activities on the VHF+ bands
Special Modes
If you’re interested in “fast-scan” TV, check out ATV-TV and the P.C. Electronics websites.
Slow-scan TV on HF and VHF is comprehensively covered at WA9TT’s website.
Meteor scatter communications is discussed in general on its Wikipedia article and more specifically to ham’s at N5KDA’s popular website. You can find the software you need and more information on K1JT’s WSJT page.
The Wikipedia article on Radio-Controlled models is a good place to start for information on using ham radio in this novel way.

Garrett Down KD6KPC of Repeaterbook.com shared this if you want to donate to his website:
To run a website like Repeaterbook.com, revenue is needed to keep it active on the web. There are bills to be paid, hosting companies to be paid, SSL certificates to be purchased, and other expenses that go along with the research and development of the data. The costs add up.
Repeaterbook has committed to keeping access to its data completely free. Since we don’t charge for the data or access to the site, we decided to incorporate ads into the site. The ads generate revenue that has been sufficient to pay the bills (most months). With the advent of ad-blocking technology, we began to see ad revenue slip. We get it. Many people don’t want to see ads and our stats indicate that up to 30% of our site visitors are using an ad blocker. Some say the performance on the site has even suffered waiting for ads to load. And come are concerned about Internet tracking through the ads (yes, Google does it).
We think we have found a solution to meet in the middle.
You can now subscribe to Repeaterbook and obtain a membership that will silence the ads on Repeaterbook. This form of obtaining revenue while quieting ads is used on qrz.com.
So now we have two option to fit your preference:
- Enjoy Repeaterbook completely free, while enduring the ads that appear.
- Sign up for a Repeaterbook subscription and silence the ads.
To take advantage of this offer, you must be a registered user in good standing.
Look at our Subscription Plans.
