A Radio Station? In Cobb?!

Calling All Stations!

Is there anybody out there willing to help us put together a radio station in Cobb, operated 24/7 by teams of young people?

CRF* is now starting (1Q2021) to develop a partnership (WIP) with another small local nonprofit which includes the goal of putting RadioCobb online and on the airwaves from a location in Cobb (near the Post Office) and possibly getting some kind of support from Lake County. It will be connected to the Cobb Area Volunteer Emergency Radio Network, which will be able to interrupt the radio station’s broadcast with brief CAVERN emergency alerts (in case of fire) as well as send out a “siren tone” over the airwaves in case of a major disaster or evacuation order.

We need feedback from the Cobb Area community. Would you please take 2 minutes to let us know a few quick things using the handy form below? We really need a few radio-savvy local people to help us launch this public information and safety service that gives young people the opportunity to serve the community both creatively and with an important purpose.


RadioCobb Community Survey #1
Just pick ONE (hopefully not the dog).
Please check all that apply to you.
If you want us to get in touch with you about this idea, we'll only use the email you give us here for that one purpose.

CAVERN on KPFZ

  Mon 30 Sept 2019
  1:00-3:00pm
  KPFZ 88.1 FM
   (Lake County public radio)

Episode 186 from http://lionslair.com/hamradio/ Thank you Ben!

CAVERN’s organizers were live on the air with radio host Ben Weiss on public radio station KPFZ, chatting about the CAVERN project and its roots, RF radio topics, organizing your community to be prepared for emergencies and the future convergence of software-defined radio (SDR) and terrestrial radio mesh networks, including the mothership VERN project’s development happening at a small nonprofit tech thinktank right here in Lake County.

Progress Report: Prototype Alpha Radio Mesh Network Nodes

CryptoRights (CAVERN’s sponsoring nonprofit) has a small development team working on the design for the prototype (alpha) hardware nodes that will (go up on rooftops and in attics) to form a mesh radio network.

Here’s a photo of our (early alpha) prototype mesh node hardware we’re using to begin alpha testing in our satellite lab:

Each harmless little prototype consists of:
(1) a CPU (RaspberryPi running our custom Linux OS) & SD Card Memory;
(2) an Antenna (USB) and
(3) a Battery (also USB).

Pretty simple… so far! Three prototype nodes (see bottom photo) have been built for development and lab testing. Just buying the components for these first prototypes on AmazonSmile, the total is around $150 each, which is why we’re working on designs to get the per-unit cost way lower so anyone can easily afford one. The more nodes, the denser the mesh, and thus the better the mesh’s performance and reliability, resulting in a safer community from wildfires, big storms and other emergencies. CryptoRights is now gratefully accepting donations (see the right side of this page), applying for grants and planning a crowdfunding campaign to fund the manufacture test nodes so we can place them with volunteer operators around every side of the mountainous region centered on Cobb — which was selected partly on the basis of its challenging topography!

We also hope to start work soon on:
(4) 100% Off-Grid Operation (a big project goal) by adding a Solar Panel (or existing panel tie-in) and a compact Charger/Inverter (make yourself a ‘wikiname’ login at the Harmless Little Project and see “SoRad“).
(5) Weatherproof Enclosure: once the technology is ready for outside testing, it will have a weatherproof enclosure that can easily be mounted onto a roof, bolted to a tower or even screwed onto a deck rail or tree branch if that’s what you have handy. Yes,if you have a very large property, you could operate several nodes to connect (with enhanced privacy) to your family and nearby friends ‘behind’ the hills… and you’d be adding density to the mesh for everyone nearby as well.

For now, the (most basic) alpha nodes will just plug into your house’s 120V power (ideally, up high in your attic) and the Battery will keep the system operating in case of a power outage.

We should have more progress to report in October!

N.B.: If you are subscribed to the Announcement list, you’ll know as soon as we begin asking for the first few volunteer Alpha Node operators.
