FCC Part 97.301 Frequency and Technical Rules Explained

47 CFR §97.301 and related sections define where amateur radio operators can transmit. This includes band allocations, frequency privileges, and technical operating limits.

Your license class determines where you can transmit—operating outside your allowed bands is a violation of FCC rules.

Core Rule

Amateur radio operators may only transmit on frequencies authorized for their license class. These frequencies are defined by FCC regulations and international agreements.

Amateur Radio Bands

HF Bands

Long-distance communication bands (e.g., 80m, 40m, 20m).

VHF Bands

Local and regional communication (e.g., 2m).

UHF Bands

Shorter range and repeater-heavy operation (e.g., 70cm).

License Class Privileges

Different license classes have different access:

  • Technician: Mostly VHF/UHF, limited HF
  • General: Most HF bands
  • Extra: Full access to all amateur bands
Operating outside your license privileges is a direct FCC violation—even if accidental.

Technical Limits

  • Power limits (covered in other sections)
  • Bandwidth restrictions
  • Emission type limitations

These rules ensure efficient and interference-free use of the spectrum.

Band Plans vs FCC Rules

Band plans are voluntary guidelines used by operators to organize frequencies by mode:

  • Not legally required
  • Widely followed for cooperation
  • Help prevent interference
FCC rules define what is legal. Band plans define what is good practice.

Common Mistakes

  • Transmitting outside your authorized band
  • Confusing band plans with legal limits
  • Using incorrect frequencies for your license class
  • Ignoring mode-specific sub-bands
  • Know your license privileges
  • Operate within authorized bands
  • Follow band plans for best practice
Summary

FCC Part 97.301 and related rules define where amateur radio operators can transmit. These rules assign frequencies and privileges based on license class.

Stay within your authorized bands, and follow band plans to operate effectively and cooperatively.
