GMRS Series #7 — Family Communication Routines, Check-Ins, and What Silence Really Means
Prep Comms
Most families don’t lose communication because radios fail. They lose it because there’s no routine, no shared rhythm, and no clear understanding of what silence actually means. In this episode, Caleb closes out the GMRS series by walking through how families should actually use radios day to day — how to structure simple check-ins, why calm routines matter more than gear, and how to respond when the radio goes quiet without panic. This episode focuses on habits and decision-making, not technology for technology’s sake. What We Cover Why communication routines matter more than...

Prep Comms
Most families don’t lose communication because the radio fails. They lose it because stress changes how people talk. In this episode, Caleb breaks down how families actually communicate on GMRS — the common mistakes that create confusion, and the simple habits that keep radio traffic calm and clear when it matters. This isn’t about gear. It’s about behavior, clarity, and confidence. What We Cover Why stress breaks radio communication The three most common family communication mistakes How talking too fast and over-explaining kills clarity A simple, repeatable family radio...

How to Actually Use GMRS as a Family
Prep Comms
Most families buy GMRS radios… then realize no one actually knows how to use them when the phones go quiet. This episode fixes that. Today we walk through the simple, practical skills every household needs to use GMRS with confidence: • The 3-button rule • How to choose the right channel group without a chart • How to know if you’re hitting a repeater • What to do when you hear nothing • The 10-second teaching script for non-technical adults • A weekly household radio routine that actually works No programming. No deep tech. Just clear steps any family can follow. Mentioned in...

GMRS #5: So Many Channels…
Prep Comms
Most new GMRS users hit the same wall: thirty channels on the screen, all looking equal… but they’re not. Some are full-power. Some are handheld-only. Some can hit repeaters. Some won’t carry your voice past the yard. In this episode, we break down GMRS the way real families actually use it: • The three channel groups that matter • What power limits mean in the real world • Which channels give you real range • Why Channels 8–14 feel so weak • The only three channels your family needs to know • How repeaters actually work on GMRS If you’ve ever wondered why GMRS feels...

GMRS: What can it Really Do?
Prep Comms
In this episode, Caleb Nelson (K4CDN | WRBR237) breaks down what GMRS can really do—and what it can’t. You’ll learn how far GMRS actually reaches, why antenna height beats transmitter power every time, and what equipment upgrades make the biggest difference for families building real communication plans. We’ll also cover license coverage, the truth about 50 watts, repeater basics, and why investing in a better antenna might triple your range overnight.

GMRS — The Family Band That Actually Works
Prep Comms
What you’ll learn (fast): Why GMRS is the practical “bigger brother” to FRS: same 22 channels, different rules, more capability. The license is simple: $35, 10 years, one license covers your whole household (apply at FCC.gov). Range reality: terrain + antennas matter. Main channels allow up to 50W transmitter output; interstitials are lower. Privacy tones ≠ privacy. GMRS is open-air. You must ID every 15 minutes and at the end. Why certified radios matter (and why new FRS/GMRS combo handhelds aren’t sold anymore). Links & resources: Free: Read: Vetted Gear:...

FRS Mini-Series Finale: Where FRS Fits in Your Family Communication Plan
Prep Comms
FRS radios are a great start, but they aren’t the whole plan. They work for kids, neighbors, and short-range use — but when the storm hits or the grid goes down, you may need more. In this episode, Caleb Nelson (K4CDN) explains how FRS fits into a complete family communication plan, including: The strengths and limits of FRS radios How GMRS, MURS, and ham radio build on that foundation Why thinking in layers — the Cascade Protocol — makes families stronger How National Preparedness Month is the right time to move from gear to plan FRS is a tool worth having, and combined with...

The 11-meter band sits within the **high-frequency (HF)** spectrum, and its properties significantly affect the performance of CB radios. Frequencies within this range can travel through the ionosphere, especially during favorable atmospheric conditions, making **skip propagation** possible. Skip propagation allows signals to bounce off the ionosphere, potentially reaching hundreds of miles beyond their typical range.
However, not all conditions favor such long-distance communication. Atmospheric disturbances, solar cycles, and interference from other devices can limit the effective range of CB radios operating in the 11-meter band. For most users, this range averages between **1 to 15 miles**, depending on the terrain and other factors.
AM vs. SSB Modes: Performance and Usage
CB radios typically operate using one of two communication modes: **Amplitude Modulation (AM)** and **Single Sideband (SSB)**. Both have their advantages and trade-offs, impacting how CB users experience clarity, range, and performance.
AM (Amplitude Modulation)
The AM mode is the default communication method for most CB radios. It works by modulating the amplitude of the radio wave to carry the audio signal. AM is relatively simple in terms of technology and is favored by truckers and casual users for local communication. However, it has limitations, particularly in clarity and range.
AM transmissions are more susceptible to **noise interference** from electrical devices, power lines, and atmospheric conditions. The sound quality tends to degrade over longer distances, and the range can be limited, typically extending no further than **5 to 10 miles** in most conditions. While convenient for general communication, AM may not offer the performance needed for long-distance or emergency communication.
SSB (Single Sideband)
SSB mode offers a significant upgrade in performance, allowing CB users to achieve greater range and clarity. Unlike AM, which transmits a full signal that includes a carrier and both upper and lower sidebands, SSB transmits only one sideband (upper or lower), removing the carrier. This makes SSB more **efficient** in terms of power and bandwidth usage.
In practical terms, SSB can extend communication range by **50 to 100%** compared to AM, making it ideal for those who need to cover larger areas. It also provides clearer audio, especially in noisy or interference-prone environments. The trade-off, however, is that not all CB radios support SSB, and it requires more precise tuning for optimal performance.
