Question E1C05:
[97.221(c)(1), 97.115(c)] Under what situation may a station transmit third party communications while being automatically controlled?  

Choices:  
A: Never  
B: Only when transmitting RTTY or data emissions  
C: Only when transmitting SSB or CW  
D: On any mode approved by the National Telecommunication and Information Administration    

Correct Answer is  B: Only when transmitting RTTY or data emissions  

Correct answer: B — Only when transmitting RTTY or data emissions

1) Why B is correct
- FCC Part 97.115(c) explicitly allows third party communications from a station that is being automatically controlled only if the station is transmitting RTTY or data emissions.
- This ties to automatically controlled digital station (ACDS) operation defined in 97.221; these stations operate with RTTY/data modes in designated segments.

2) Why the other choices are incorrect
- A: Never — Incorrect because 97.115(c) provides an explicit exception for RTTY/data emissions.
- C: Only when transmitting SSB or CW — Incorrect; phone (SSB) and CW are not permitted for third party communications while the station is under automatic control.
- D: On any mode approved by the NTIA — Incorrect; amateur rules are governed by the FCC (Part 97), not the NTIA, and FCC rules restrict this to RTTY/data only.

3) Useful rules of thumb
- Rule: If the station is under automatic control and you want to pass third party traffic, it must be RTTY/data.
- Phone or CW + automatic control + third party = not allowed.
- Ensure operation is within the ACDS subbands per 97.221 when running automatically controlled RTTY/data.
