Which methods can determine compliance with FCC RF exposure rules?

Use OET Bulletin 65 calculations, computer modeling, or calibrated measurements.

  1. Only an SWR reading
  2. Only the transmitter manual
  3. Calculations, modeling, or calibrated measurements ✔

Why: Compliance may be evaluated using accepted calculations, computer models, or measured field strength. The measurement method requires calibrated equipment.

Huh, didn't know that: Different station layouts may make one evaluation method more practical than another.

The dad joke
The station modeled good behavior before measuring it.
