Intro to Network Control

A power transformer suddenly explodes right behind your house in the country on ten rural acres. By the time you get to the window, the flames have knocked out your telephone and internet. As you watch, sparks rain down and start a huge fire a few feet from your home. Would you let the fire burn while you drive to a nearby town for assistance?
How can you quickly get help?

Use your handheld radio!

But, you say, you don’t know how to use a radio or who might be out there listening?

That’s where CAVERN comes in. We’re organize people and showing them how to get the Cobb Area community prepared to communicate when an emergency hits.

Every week (twice weekly during fire season) we meet on the air for a Radio Check-In to make sure everyone’s OK and listening for anyone who isn’t OK. These Check-Ins are managed by one of our volunteers who serves as Network Control. “NetCon” is the person who provides the ‘control tower’ function, directing everyone to speak in order so we learn how to listen as much as we practice how to say things efficiently when our turn comes to speak.

Ideally, everyone in our community will learn how to be Network Control in case there’s an emergency in their own backyard and they need to call on others to rally to help them. Here’s an easy step to get you started: learn how to be the director in a directed radio network (aka “Network Control”). It’s quite easy to do — just use a script (this one, or an improved version). It’s important to write down who you hear checking in, so we made it easy: just print out the last page!

PAGE 1 of the PDF features our RS Code matrix, which can help you tell people quickly how well you can hear them (in case there’s anything they can do to improve their signal, like standing a few feet away).

PAGES 2—4 are an early draft of the VERN Network Control Script (v071d), adapted for our current CAVERN network groups. CryptoRights is working with the CAC Communications committee to improve this Script through trial and error and we will introduce the improved material back into a future VERN script. Meanwhile, folks can become familiar with how we conduct the weekly Check-Ins. Everyone is encouraged to try being “NetCon” at least once or twice.

PAGE 5 is the current CAVERN Roll Call Sheet (RCS), included for anyone who wants to try serving as Network Control during future weekly Check-ins.

We appreciate any constructive feedback you might send to: NetCon [at]
