Question
Why should you not set your transmit frequency to be exactly at the edge of an amateur band or sub-band?
Answer Options
- A) To allow for calibration error in the transmitter frequency display
- B) So that modulation sidebands do not extend beyond the band edge
- C) To allow for transmitter frequency drift
- D) All these choices are correct
Correct Answer: D
Explanation
All three reasons are valid operational and regulatory considerations. The FCC requires that all of your transmitted energy must remain within the assigned band. When you transmit a signal (voice, CW, or digital), it creates sidebands (extra energy) that extend on either side of the main frequency. If your center frequency is too close to the edge, these sidebands could illegally fall outside the band.
\Furthermore, small calibration errors or minor frequency drift due to temperature changes could also push your signal out of band. Setting your frequency slightly inside the legal boundary acts as a buffer against all these potential violations.
