Ham Radio: The Test..........
Prep Comms
Ham radio testing is where a lot of people stall. Not because it’s hard. Not because it’s unfair. And not because access is restricted. In this episode, I talk plainly about why testing exists, why it’s required, and why the arguments around it haven’t changed in years—even as access has become easier than ever. I’ve watched this cycle repeat long enough to recognize the pattern. People fear the test, pass the test, and then freeze because they don’t know what to do next. The test was never the real problem. This isn’t test prep. It isn’t a debate. And it isn’t a defense of...

Ham Radio: Why I Started the Journey
Prep Comms
Ham Radio: Why I Started the Journey (and Where “Ham” Came From) Ham radio didn’t start as a hobby for me. In this episode, I talk through why I finally took amateur radio seriously, what problem I was trying to solve, and why ham radio kept showing up at the end of the communications conversation. I also touch lightly on the history of the amateur radio service and where the term “ham” came from—not as trivia, but to clear up common misconceptions. This isn’t a tutorial, test prep, or a gear review. It’s a conversation about motivation, capability, and why ham radio became...

Ham Radio, the Last Act
Prep Comms
Ham radio usually comes up at the end of the conversation about communications. Not first, and not early—after people have already tried other options and figured out what feels easy and what doesn’t. In this episode, I talk through why that happens. I walk through patterns I’ve seen over time: how people approach communication planning, how radios get bought and set aside, and why plans often fall apart when they’re never used or practiced ahead of time. This isn’t a tutorial or a licensing guide. I’m not explaining how to get started or what equipment to buy. It’s simply a...

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...

GMRS Series #7 — How Families Actually Communicate on GMRS (and How to Keep It Calm)
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...

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...

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.
