What is the customary minimum frequency separation between SSB signals under normal conditions?
Between 150 and 500 Hz
Approximately 3 kHz
Approximately 6 kHz
Approximately 10 kHz
The correct answer is: Approximately 3 kHz
The customary minimum frequency separation between SSB (Single Sideband) signals under normal conditions is approximately 3 kHz. This spacing is generally accepted to prevent interference between adjacent signals when operators are transmitting and receiving on similar frequencies. In SSB operation, the transmitted signal occupies a bandwidth that is typically about 2.7 kHz for standard voice communications. To ensure clear reception and to minimize the chances of overlapping signals or interference from adjacent channels, a separation of around 3 kHz is advisable. This allows receivers to adequately filter out unwanted signals and maintain quality communication. Understanding the importance of frequency separation is crucial for effective frequency management in amateur radio operations, as it helps preserve the integrity of communication among users in the same frequency band.
