🔍 Key Concepts

• Historical MF (medium frequency) radiotelegraph distress and calling band around 500 kHz • MF working frequencies used for normal ship–shore traffic near, but not on, the distress band • SOLAS/US requirements that a main receiver cover both the distress band and the adjacent working band

💭 Think About

• First, locate the well-known international distress frequency in the 350 to 515 kHz range and think about why that band must be covered. • Next, ask yourself: for routine traffic (not distress) where, in frequency, are the closely associated working channels placed relative to the distress band? • Look at which option represents a continuous band immediately adjacent to, and logically paired with, the 350–515 kHz range used historically for MF radiotelegraphy.

✅ Before You Answer

• Verify which choice represents a medium-frequency (MF) band commonly used for ship–shore working traffic, not HF or LF. • Check which frequency range is contiguous or nearly contiguous with the 350–515 kHz band, as regulatory receivers were often required to span both without a gap. • Eliminate any ranges that are more typical of broadcast bands or HF maritime allocations rather than MF distress/working channels.
