Question
Which sideband is normally used for 10 meter HF, VHF, and UHF single-sideband communications?
Answer Options
- A) Upper sideband
- B) Lower sideband
- C) Suppressed sideband
- D) Inverted sideband
Correct Answer: A
Explanation
In SSB operation (T8A01), you must choose whether to transmit the upper or lower sideband. Amateur radio convention dictates which sideband is used on which bands to ensure all operators are listening on the same side and can communicate.
For most amateur bands at 10\text{ MHz} and above (including the 10-meter HF band and all VHF and UHF bands), the convention is to use Upper Sideband (USB). For HF bands below 10\text{ MHz} (like 80m, 40m, etc.), Lower Sideband (LSB) is typically used.
