Special Audible Signals


VERN • Special Signal Tones

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 keypad as described here for the two basic signal tones.

A standard GMRS radio, the BTECH GMRS-V1

NOTE: FRS radios generally have no keypad and are NOT able to produce tones.


SPECIAL SIGNALS

For Network Control & Group Leaders ONLY, three (3) additional special audible signals are proposed. Most VERN operators will not send these but could hear them.

(3) Danger Level Signal

Keys                                                  Name                                      
 ###  ###  ###  ###  ###            Danger !
 
###  ###  ###  ###  ###  ###  ###  ###  ###  ###   HEY !!

• 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.
