Which mode is normally used when sending RTTY signals via AFSK with an SSB transmitter?
- A.USB
- B.DSB
- C.CW
- D.LSB (correct answer)
WhyRTTY sent via AFSK through an SSB transmitter is normally sent on lower sideband. RTTY sent via AFSK through an SSB transmitter is conventionally sent on lower sideband, regardless of the underlying HF band, a fixed convention rather than something that follows the general USB-above-10-MHz voice rule, answer D. Upper, double, and plain CW sideband/mode labels don't describe the actual RTTY-via-AFSK convention.
