Question
What is the maximum symbol rate permitted for RTTY or data emission transmissions on the 10-meter band?
Answer Options
- A) 56 kilobaud
- B) 19.6 kilobaud
- C) 1200 baud
- D) 300 baud
Correct Answer: C
Explanation
For RTTY or data emissions transmitted on the 10\text{-meter} band (28 \text{MHz}), FCC Rule \S 97.305(\text{c}) and \S 97.307(\text{f})(4) establish a maximum symbol rate of 1200 baud. This is significantly higher than the 300 baud limit on the lower HF bands.
This higher rate is permitted because, due to their physical properties, the VHF and higher-frequency spectrum generally supports wider bandwidths and faster data rates without causing undue interference. This allows amateur operators to utilize modern, higher-speed data protocols on the 10\text{-meter} band and above.
