What is the recommended minimum separation for SSB transmitting frequencies to reduce interference?

1 kHz to 2 kHz
2 kHz to 3 kHz
3 kHz to 5 kHz
500 Hz to 1 kHz

The correct answer is: 2 kHz to 3 kHz

The recommended minimum separation for SSB (Single Sideband) transmitting frequencies to effectively reduce interference is indeed between 2 kHz to 3 kHz. This separation is important because SSB signals can produce adjacent channel interference, which means that signals operating too close together can cause significant distortion or disruption in communications. By maintaining a separation of 2 kHz to 3 kHz, operators can minimize the risk of overlapping signals, allowing for clearer communication and better overall signal quality. The wider frequency spacing helps to ensure that the unique characteristics of SSB modulation are preserved, allowing each conversation to be received without interference from adjacent frequencies. Although other separations are mentioned, they either do not provide adequate protection against interference or are too narrow for optimal SSB communication. Therefore, adhering to the 2 kHz to 3 kHz recommendation is especially crucial in crowded amateur radio bands, where many operators may be transmitting at the same time.
