Question
What term describes an amateur station that is transmitting and receiving on the same frequency?
Answer Options
- A) Full duplex
- B) Diplex
- C) Simplex
- D) Multiplex
Correct Answer: C
Explanation
The term used to describe an amateur station operating by transmitting and receiving on the same frequency is Simplex. This mode is used for direct, local, line-of-sight communication without the aid of a repeater.
Simplex operation is encouraged whenever possible because it frees up repeater resources for more distant or widespread communications that truly require a relay. Conversely, repeater systems operate in a duplex mode (T2A07), using two different frequencies.
