🔍 Key Concepts

• Difference between simplex and duplex operation in maritime radio communications • How ship–ship versus ship–shore communications typically use VHF channels • ITU definition of a simplex channel in contrast to paired transmit/receive frequencies

💭 Think About

• Ask yourself: In simplex operation, do both stations use the same frequency in turn, or separate frequencies at the same time? • Consider how you normally talk on a handheld VHF: when you press the PTT button, are you listening and transmitting on the same or different frequency? • Which options actually describe duplex (paired) operation rather than simplex operation?

✅ Before You Answer

• Be clear on the definition of simplex (one frequency, alternating transmit/receive) vs duplex (two different frequencies, simultaneous transmit/receive). • Check which choices describe a single frequency used by both stations rather than a frequency pair. • Verify that you are thinking of standard VHF marine channels used between ships, not special coast station repeated channels.

Question 1 of 20

An ITU simplex channel frequency assignment is defined as:

Transmit and receive frequencies must be identical .

Transmit and receive frequencies must be different.

Transmit and receive frequencies may be different, depending on whether communications are ship-shore or ship to ship.

Transmit and receive frequencies are different regardless of emission mode.
