FCC Part 97.119 Station Identification Explained
47 CFR §97.119 explains how amateur radio stations must identify themselves on the air. This rule is one of the most important operating requirements in amateur radio because it ties every transmission to a valid station and licensed operator.

Core Identification Rule
Every amateur station must transmit its assigned callsign to identify itself during communications. This requirement applies across normal voice operation, Morse code, digital modes, repeater use, and many automatic station functions.
The purpose of this rule is simple: every signal on the amateur bands must be traceable to a properly authorized station. Station identification protects accountability, supports enforcement, and helps other operators know who is on the air.
- Voice communications must identify the station clearly
- CW stations must send the assigned callsign in Morse code
- Digital stations must include identification in a permitted readable form
- Automatic and repeater systems must still meet identification requirements
When You Must Identify
FCC Part 97.119 requires identification at specific intervals during operation:
- At least once every 10 minutes during a communication
- At the end of a communication
This means you cannot simply identify once at the beginning of a long exchange and stop there. If the communication continues, you must keep identifying at the required interval. At the end, you must identify again.
How to Identify
Voice
Speak your callsign clearly. Standard phonetics may be used when helpful, especially in weak-signal or noisy conditions.
CW
Transmit your callsign in Morse code at a readable speed. The identification must still be understandable and accurate.
Digital
Include your callsign in the digital transmission using a method permitted by the mode and FCC rules.
The important point is that identification must be clear and tied to the station actually transmitting. Nicknames, first names, tactical labels, or made-up identifiers are not substitutes for your assigned FCC callsign.
Special Identification Cases
Some operating situations involve special station identification considerations:
- Repeaters: Repeaters must identify automatically at the required intervals
- Remote operation: A remotely controlled station still identifies with the proper assigned callsign
- Special event stations: Special event callsigns may be used when properly authorized
- Club stations: Club callsigns must be used appropriately under club station authority
Even in these cases, the rule does not disappear. The station still needs to identify correctly according to FCC requirements.
Real World Examples
✔ Proper Identification
- You give your callsign every 10 minutes during a long conversation
- You identify again at the end of the contact
- You use your assigned callsign clearly and accurately
- A repeater automatically identifies at the required interval
✘ Improper Identification
- Forgetting to identify during a long conversation
- Ending a QSO without giving your callsign
- Using a nickname instead of a callsign
- Using another operator’s callsign incorrectly
- Assuming someone else on frequency can identify for you
Common Mistakes
- Not identifying every 10 minutes
- Forgetting to identify at the end of the communication
- Using an expired, incorrect, or unauthorized callsign
- Assuming digital or repeater use changes the rule
- Believing a tactical label replaces a legal station identification
- Identify every 10 minutes
- Identify at the end of communication
- Use your assigned callsign
- Make identification clear and readable
- Do not rely on nicknames or informal labels
FCC Part 97.119 requires every amateur radio station to identify itself using a valid callsign. This rule applies across voice, CW, digital, repeater, and many automatic operating situations.
In simple terms, if your station is transmitting, it must identify correctly. Proper identification is a basic legal requirement and a core part of responsible amateur radio operation.
Frequently Asked Questions
How often do I have to identify on ham radio?
You must identify at least once every 10 minutes during a communication and again at the end of the communication.
Can I use my name or nickname instead of my callsign?
No. Your FCC-assigned callsign is the required legal station identification.
Do repeaters and remote stations still have to identify?
Yes. Repeaters, remote stations, and other station types must still meet FCC identification requirements.
What happens if I forget to identify?
Failure to identify properly is an FCC rules violation and is one of the most common amateur radio operating mistakes.
