Question 1 of 27070

🔍 Key Concepts

• VHF-FM (Very High Frequency – Frequency Modulation) is a short-range line-of-sight marine band used for bridge-to-bridge, distress, safety, and calling • HF/MF (High Frequency/Medium Frequency) bands are used for longer-range radiotelephone and digital selective calling, and often expressed directly in kHz • International distress and hailing channels differ between the VHF band and the MF/HF bands

💭 Think About

• First separate the answer choices by which ones are clearly VHF-FM channels and which ones are MF/HF radiotelephone frequencies in kHz • Ask yourself: which specific VHF channel is defined internationally for distress, safety, and calling (hailing) in the marine VHF band? • Consider which channels/frequencies are used for ship‑to‑ship bridge‑to‑bridge safety versus general distress/safety/hailing

✅ Before You Answer

• Confirm which choices are labeled as VHF channels with frequencies in MHz, versus those listed only as kHz values (MF/HF) • Recall the internationally recognized VHF distress, safety, and calling channel used worldwide for initial contact and emergencies • Verify that the chosen option matches both the correct band (VHF-FM) and the specific purpose (distress, safety, and hailing) described in the question
