FCC Part 97.7 Control Operator Required Explained

47 CFR §97.7 requires that every amateur radio station must have a control operator whenever it is transmitting. This rule ensures that every signal on the air is legally supervised and accountable under FCC regulations.

Every transmission must be under the control of a licensed operator. If no control operator is responsible, the transmission is illegal.

The Core Rule

An amateur station may only transmit when a control operator is designated. That control operator is responsible for ensuring the station complies with all FCC rules.

This applies to:

  • Voice communications
  • Digital transmissions
  • CW (Morse code)
  • Automated systems

Who Can Be a Control Operator

Licensed Amateur

Must hold a valid FCC amateur radio license.

Proper Privileges

Must have privileges for the frequency and mode being used.

Designated Operator

Must be clearly responsible for station operation.

When a Control Operator Is Required

  • Any time the station is transmitting
  • Even during remote operation
  • Even during automatic operation
  • For repeaters, beacons, and digital nodes
If a station transmits without a control operator, it is a direct violation of FCC Part 97.

Automatic and Remote Control

Stations do not always need a person physically at the radio, but they must still be under control:

  • Local control: Operator is at the station
  • Remote control: Operator controls the station from another location
  • Automatic control: Station operates automatically under pre-set rules

Even with automatic systems:

  • A control operator must be designated
  • The operator is still responsible for compliance
  • The station must follow all applicable rules

Real World Examples

✔ Legal Operation

  • You are licensed and operating within your privileges
  • You are designated as the control operator
  • Your transmissions follow FCC rules

✘ Illegal Operation

  • Unlicensed person transmits without supervision
  • Automated system runs with no responsible operator
  • Operator exceeds their license privileges

Common Mistakes

  • Thinking the radio itself is licensed
  • Assuming remote operation removes responsibility
  • Believing repeaters have no operator accountability
  • Letting unlicensed users transmit unsupervised
  • A control operator must always be designated
  • The operator must be licensed
  • The operator must follow their license privileges
  • Responsibility exists even for automatic stations
Summary

FCC Part 97.7 requires every amateur radio transmission to be under the control of a licensed operator. This ensures that all activity on the air is legal, accountable, and within FCC rules.

If a signal is being transmitted, someone must be responsible for it.
