Extra exam question E1B08

Subelement E1, COMMISSION RULES· Group E1B · 47 CFR §97.121

E1B08 · §97.121

What limitations may the FCC place on an amateur station if its signal causes interference to domestic broadcast reception, assuming that the receivers involved are of good engineering design?

  • A.The amateur station must cease operation
  • B.The amateur station must cease operation on all frequencies below 30 MHz
  • C.The amateur station must cease operation on all frequencies above 30 MHz
  • D.The amateur station must avoid transmitting during certain hours on frequencies that cause the interference (correct answer)

WhyIf a well-designed broadcast receiver still experiences interference from an amateur station, the FCC may require that station to avoid transmitting during certain hours on the frequencies causing the problem. Under §97.121, if an amateur station's signal interferes with domestic broadcast reception even though the affected receivers are well designed, the FCC can require the amateur station to avoid transmitting during certain hours on the specific frequencies causing the problem, rather than shutting the station down outright, answer D. A full cessation of operation, whether sitewide or across an entire frequency range above or below 30 MHz, is a heavier remedy than what this particular rule actually authorizes.
