🔍 Key Concepts

• Difference between voice and SITOR/NBDP operation on MF-HF sets • Role of filters and bandwidth in digital vs voice modes • Which stages (RF, audio, IF, PLL) are common to both modes and which are more critical to narrow‑band data

💭 Think About

• If voice works normally, which parts of the transceiver signal chain are definitely functioning? • Which of the listed components is specifically associated with the narrow bandwidth required for SITOR/NBDP? • Think about where a failure would affect only SITOR and not ordinary voice communications.

✅ Before You Answer

• Identify which stages are shared by both voice and SITOR (these are less likely the cause). • Recall typical bandwidth requirements: voice vs a narrow‑band direct printing mode like SITOR/NBDP. • Match each option to the function it serves in the receiver: RF amplifier, audio amplifier, IF filter, phase‑locked loop.
