1. Technical Overview of SSB on CB Frequencies:

• Efficiency & Range: SSB (Single Sideband) modulation is more efficient than standard AM because it suppresses the carrier and one of the sidebands, allowing more of the transmitter’s power to be used for the information-carrying signal. This can result in improved range and better signal-to-noise performance.

• Bandwidth & Tuning: SSB signals can be more susceptible to tuning errors because they use narrower bandwidth. Operators must precisely reinsert the suppressed carrier at the receiver to correctly demodulate the signal, making proper training essential.

2. Regulatory Considerations:

• United States Regulations: The Citizens Band (CB) radio service is governed by FCC Part 95. Under these rules, only Amplitude Modulation (AM) is allowed on the CB channels. Although many CB radios are marketed with SSB capability, using SSB on CB channels in the United States is prohibited and may result in enforcement actions or fines.

• International Variations: In some other countries, regulations may permit the use of SSB on CB channels. For example, certain regions in Europe or elsewhere might allow SSB operation, but users should always consult local regulatory guidelines before operating in SSB mode.

3. Practical Implications for Emergency Preppers:

• U.S. Preppers: If you are based in the United States, you must adhere to AM-only operation on CB channels. For the benefits of SSB (more extended range, increased efficiency), consider obtaining an amateur radio license and operating on HF bands, where SSB is fully permitted.

• International or Multi-Jurisdictional Operations: If you’re operating in a jurisdiction where SSB on CB is allowed, you can take advantage of the improved performance—but be mindful that successful SSB operation requires more precise tuning and regular training drills to ensure signal clarity and effective communication.

4. Summary:

While SSB offers clear technical advantages for long-range and efficient communications, its use on CB channels is subject to strict regulatory limits in the United States. Emergency preppers in the U.S. should rely on AM for CB operations and consider using licensed amateur HF bands if SSB capabilities are needed. Operators must invest in proper equipment tuning and training in regions where SSB on CB is permitted to maximize its benefits.

This overview should help you understand the potential benefits and regulatory and technical limitations of using SSB on CB channels for emergency communications.
