Network Control and Group Leaders (with a GMRS radio+license) could use additional audible DTMF tones to indicate certain conditions on a Volunteer Emergency Radio Network. These tones are sent using the radio’s numeric keypadas described here for the two basic signal tones.
NOTE:FRS radios generally have no keypad and are NOT able to produce tones.
For Network Control & Group LeadersONLY, three (3) additional special audible signals are proposed. Most VERN operators will not send these but could hear them.
• Press “pound” key 3x rapidly (a ‘triple-tap‘) • Pause for one (1) second between each ‘triple-tap’ • Repeat ‘triple-taps’ 5x-10x (more indicates higher danger) • 10x = highest possible danger level (catastrophe: almost never used)
NOTE: These signals are sent by Network Control —> Only to the Emergency Alert Channel (FRS 9, GMRS 33) —> Only when there is useful incident info to broadcast. —> Followed by: A brief incident summary. More info on Main VERN Repeater channel (FRS 8, GMRS 23)
(4) Group Leaders / GMRS “Gather” Signal
Keys Name 88 33 77 66 “Group Leaders Gather“
• ‘Musical’ tone for NetCon/Group Leaders to call all GMRS operators* • Press & Hold each key Twice (2x) holding for a half second each • Pause 1 second between pairs
NOTE: Spells “VV EE RR NN” for Volunteer Emergency Radio Network operators. Variations on this are still being proposed and refined. * GMRS operators are the network‘s backbone, leading the groups and relaying other people who cannot be heard: this calls them together for something important.
(5) Test Signal
Keys Name 218 218 218 “Start Test / End Test“
• Used by operators to: test the Repeater and train on using signals. • Press each key Twice (2x) holding for a half second each press. • Pause 1 second between pairs. • Preceded by saying “START Test Alert” out loud. • Followed by saying “Test Alert END” out loud.
As the 2020 fire season draws to a (hopefully quick) close, it gives us all time to participate in a discussion about public safety and radios around Cobb Mountain. Especially relevant —while things are fresh in our minds after a few nearby fires recently grew into the first “gigafire”— is what have we all learned we still need to do?
An idea has been floated on the CAVERN Talk list to bundle different PDF information sheets together into a CAVERN Member… Booklet? …Package? As a benefit of being a CAVERN volunteer/member, you get the collected wisdom of the Community assembled in one convenient PDF package that you can print pages from for your refrigerator or bulletin board.
What pages/chapters/sections/etc do you members of the CAVERN community think the Member materials package should contain? Is a PDF file enough? Should we also organize things like bumper-stickers, tee shirts, lawn signs, etc?
Here are a few Example Ideas: + CAVERN Channel Guide (1pg Guide/128 channels/Printable) + CAVERN Member DB (Members’ firstname+callsign/all 6 Groups) + User Guide for <radio model> (1pg/Printable) + GMRS Licensing Guide (upgrade from FRS/listen to GMRS/talk) + RS Codes (how to describe someone’s signal quality on air) + Audible Signal Tones (basic ops, emergencies & special uses) + Emergency Radio Instructions (what to do/emergency radio stuff) + Pandemic Radio Guide (radios & public health) + Network Control Script (what I read if I need to lead) — Anything else to add, Cobblers?
Please make your suggestions in a Comment (below).
#2 • HELP
PLEASE, WILL YOU HELP assemble any of these 1-page documents, using information already available on the https://CAVERN.mobi website?
(1) The most basic is “Announcements” which sends out general CAVERN info (meetings, news, etc) 1-3 times a month.
(2) Next is “Alerts” which ONLY broadcasts urgent emergency info like evacuations, ongoing fire threats, power outages, sudden lightning storms, etc. If things are going well, you’ll almost never get anything from Alerts, but you have to be subscribed to get the important stuff!
HelloEverybody, We hope you’re safe right now as the many fires sparked by lightning strikes (over 10,000 in the first August storms), are flaring up all over the state and already stretching CalFire’s resources dangerously thin. Fires are continuing to run in multiple directions and impact multiple communities. There are now over 500 fires in California (including 23 major “complex” fires).
“LNU Lightning Complex Fire” (LNU = Lake Napa Unit) Fatalities:5 (plus 4 injuries — as of 24 Aug) Counties Affected: Lake, Napa, Sonoma, Yolo & Solano Multiple Blazes: Hennessey, Gamble, 15-10, Spanish, Markley, 11-16, Walbridge (13-4). Started: 17 Aug 2020 Acres Burned:350,000+ acres (as of 24 Aug) Structures:871+ destroyed, 234+ damaged, 30,500+ threatened (as of 24 Aug) Containment:22% (as of 24 Aug) —— 98%(as of 26 Sep) ——————— LNU Lightning Complex(3 fires), Sonoma-Lake Napa Unit, Cal Fire. IMT 1 (Cal Fire Team 2). Two miles north of Barro, CA. Chapparal, tall grass and timber. Extreme fire behavior with long-range spotting, short-range spotting and wind-driven runs. Numerous structures, energy and communication infrastructure threatened. Evacuations, area, road and trail closures in effect.

NOTE: to tune in 7-digit freqs, use Menu on your radio to set the “Step” to “2.5“, the smallest increment. On some radios, the last digit is just visible in a very tiny font on the radio’s display.
* CF 24/7 Info NOTE:the St Helena dispatch command center is handling these calls and is already stretched thin from coordinating CF’s dozens of fire engine crews. The voicemailbox may be full when you call andif it’s very busy there may be nobody able to answer, but: a 911 operator may call you back to make sure you’re not in imminent danger, so please call only w/serious issues.
