GMRS: What can it Really Do? Oct 24, 2025

Show notes

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 Oct 16, 2025

Show notes

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).

FRS Mini-Series Finale: Where FRS Fits in Your Family Communication Plan Sep 09, 2025

Show notes

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 clarity, it's what keeps families connected.

FRS Mini-Series: The Gear That Works (and What to Avoid) Sep 03, 2025

Show notes

FRS radios aren't all created equal. Some blister-pack sets are cheap toys that break in a weekend, while others are solid enough to trust on family trips or in an emergency.

In this third episode of the FRS Mini-Series, Caleb Nelson (K4CDN) takes a practical look at the gear:

What really matters in an FRS radio (durability, batteries, usability)
Why you shouldn't believe the "35-mile range" marketing
The difference between throwaway blister packs and quality FRS options
Caleb's go-to pick for a reliable family radio

This isn't about buying the most expensive radio on the shelf — it's about choosing gear that works when your family needs it.

And with September being National Preparedness Month, there's no better time to make sure your radios are ready.

20 Years After Katrina: Remembering Carl (KB5WMY-SK) and Amateur Radio's Role Aug 29, 2025

Show notes

August 29, 2005. Hurricane Katrina slammed the Gulf Coast, the levees failed, and the water swallowed entire neighborhoods. Phones went dead. Power grids collapsed. Families were cut off and 911 calls were rerouted anywhere a signal could land.

In the middle of that chaos were volunteers — amateur radio operators who carried their share of the load when the systems failed.

One of them was Carl, KB5WMY (Silent Key). In 2015, he sat down with me to share his story of working at the Bossier Parish 911 center after Katrina. Carl spoke openly about the calls he could help, the ones he couldn't, and the weight of serving in those days.

Now, on the 20th anniversary of Katrina, we honor Carl's memory and service by replaying that full conversation. It's a behind-the-scenes look at how ordinary people with radios made a difference when everything else went silent. vist www.prepcomms.com for more including the bonus audio material

FRS: Real-World Family Use Cases Aug 26, 2025

Show notes

FRS radios aren't long-range or flashy, but they're still one of the most useful family tools you can own.

In this episode of the Prep Comms Podcast, Caleb Nelson (K4CDN) dives into how families actually use FRS today, including:

Keeping kids connected in the neighborhood
Calling everyone home for dinner without shouting
Car-to-car communication on road trips and caravans
Staying in touch at theme parks, malls, and campgrounds
Why short range and lack of privacy don't have to be deal-breakers

FRS may not be perfect, but it works — and when it comes to family connection, that's what matters most.

What is FRS and Why It Matters Aug 19, 2025

Show notes

In 1996, the FCC created the Family Radio Service (FRS) to give everyday families a simple, free, and legal way to stay connected.

You've probably seen these radios before — blister packs on the shelves at Walmart, Bass Pro, or Target promising 30 miles of range. The truth? They don't go nearly that far, but they've kept families connected for decades.

In this first episode of our FRS Mini-Series, Caleb Nelson (K4CDN) shares:

The history of FRS and why the FCC gave it to the public
How blister-pack walkie talkies became household items in the 90s and 2000s
The real strengths of FRS (simple, free, license-free)
The real limits (range, fixed antennas, crowded channels)
Why FRS still matters in your family's communication plan today

Whether you've already got a set sitting in a drawer or you're new to radios, this episode will help you see FRS in a whole new light.

Is MURS Still Worth It? Aug 13, 2025

Episode 4 – Is MURS Still Worth It? Why This Forgotten Band Might Be the Most Reliable Tool in Your Family's Kit

After four episodes, we're wrapping up the MURS Mini-Series with a hard look at one question—does MURS still have a place in 2025?

For 15+ years, I've used MURS radios on our farm for everything from driveway alerts to in-vehicle comms on family road trips. In this episode, I'm breaking down:

Real-world MURS performance from long-term use
Why antennas matter more than radios (and my trusted picks)
How MURS compares to FRS, GMRS, CB, and ham radio today
Who MURS is perfect for—and who should look elsewhere

If you've been wondering whether to add MURS to your comms plan—or keep using it—you'll have the answers after this.

What MURS Can't (and Can) Really Do Aug 04, 2025

Show notes

Digital Modes, Text Messaging, Repeaters—and Why Clarity Matters

In this episode of the Prep Comms Podcast, we dive into one of the most misunderstood parts of MURS radio: digital modes.

Is digital really banned on MURS? Can you send a text? What about crossband repeaters or modes like MT63, RTTY, or APRS?

Caleb clears the air by breaking down what the FCC actually allows—and where people still cross the line. From legal analog data modes to banned digital voice, this episode brings clarity to a confusing corner of the radio spectrum.

We'll also hit:

Texting over MURS (yes, it's possible)
Why repeaters—including crossband—are a no-go
How your antenna system makes or breaks signal strength
What "manual control" and bandwidth limits really mean
