🔍 Key Concepts

• SITOR / NBDP operating modes (difference between ARQ Mode A and FEC Mode B) • What Forward Error Correction (FEC) is designed to do in a noisy HF radio environment • Effect of static crashes and noise on character reception and how redundancy helps

💭 Think About

• Ask yourself: in FEC mode, does the receiver need to talk back to the transmitter, or does the transmitter add protection in another way? • Think about how sending information more than once can help when some characters are distorted by static crashes. • Consider which option actually describes an error-correction feature, and which are unrelated side effects or limitations.

✅ Before You Answer

• Verify which SITOR mode uses repeat transmission of characters to combat errors without needing acknowledgements (ARQ). • Check if FEC is intended to reduce the error rate or if it affects things like flow rate, synchronization, or idle characters instead. • Make sure the statement you choose directly relates to how FEC works in noise/static, not just a general radio behavior.
