Section 73.61 requires that AM stations with directional antennas make field strength measurements and partial proofs of performance. The results of the field strength measurements and proof of performance must be maintained in stations' logs, records or files. Data is used by licensees to ensure adequate interference protection is maintained and that antenna is operating properly and by FCC staff in field inspections/ investigations.
