Question E1C04:
What is an IARP?  

Choices:  
A: A permit that allows US amateurs to operate in certain countries of the Americas  
B: The internal amateur radio practices policy of the FCC  
C: An indication of increased antenna reflected power  
D: A forecast of intermittent aurora radio propagation    

Correct Answer is  A: A permit that allows US amateurs to operate in certain countries of the Americas  

Correct answer: A — A permit that allows US amateurs to operate in certain countries of the Americas

Why A is correct:
- IARP stands for International Amateur Radio Permit.
- It is a CITEL-based reciprocal operating authorization that lets US-licensed amateurs operate temporarily in participating countries in the Americas without obtaining an individual license from each country.
- US hams typically obtain an IARP via the ARRL and carry it along with their FCC license and proof of US citizenship.

Why the other choices are incorrect:
- B: Not a policy. The FCC does not have an “internal amateur radio practices” document called IARP.
- C: Reflected power relates to VSWR/return loss, not IARP. There’s no “IARP” measurement in antenna systems.
- D: Aurora propagation forecasts have nothing to do with licensing or permits; IARP is a regulatory document, not a propagation term.

Rules of thumb:
- CEPT = Europe (and some others); IARP = the Americas (CITEL countries).
- Carry both your FCC license and your IARP when operating abroad under these privileges.
