🔍 Key Concepts

• HF (high frequency) radiotelephone procedures vs. VHF procedures • Role of public correspondence (coast) stations and which bands/modes they typically use • Difference between radiotelephone voice and NBDP/SITOR (narrow-band direct printing) calling procedures

💭 Think About

• Ask yourself: on the high seas HF voice circuits, how does a ship normally get the attention of a coast station before passing traffic? • Consider which calling frequency or channel the vessel would use first: is it a distress/calling channel, a data-printing channel, or a known monitored working channel? • Think about whether public correspondence stations are limited to data modes only or if they also use voice (radiotelephone) for routine traffic.

✅ Before You Answer

• Verify which method is used to initiate HF voice contact: is it via radiotelephone or NBDP/SITOR printing? • Check whether VHF Channel 16 is appropriate for a question that clearly specifies high seas (HF) communications. • Confirm whether public correspondence stations are allowed/required to operate only SITOR (NBDP) or if they can also handle radiotelephone voice traffic.
