Allowed radios. Individual responsibility.
FRS, GMRS, and amateur radio are allowed. Follow all applicable federal laws, FCC rules, and federal guidelines, including licensing, equipment authorization, frequency, power, emissions, identification, and permitted uses. Event approval never replaces those obligations.
FRS
No individual FCC licenseUse an FCC-certified FRS radio within the service’s rules. Selecting an FRS frequency on an amateur or GMRS radio does not make it an FRS radio.
FRS rulesGMRS
FCC GMRS license requiredOperate under your own valid license or an eligible immediate family member’s license as permitted. A teammate’s license does not cover you merely because you share a team. Follow equipment and call-sign identification rules.
GMRS licensingAmateur radio
Licensed control operator requiredStay within your license privileges and Part 97. Follow identification rules and restrictions on business or pecuniary-interest traffic and messages encoded to obscure their meaning. A license does not authorize every event use.
Amateur radio rules/ Build your connection
More than voice radio.
Any legal communication method may be used within the event rules: voice, data, wired, wireless, or mesh networking. Bring your approach, disclose equipment through the review process, and maintain a way to reach staff.

About OpenMANETReticulum
A networking stack that works across different underlying communication links.
About ReticulumA software name is not a radio authorization. Legality depends on the hardware, frequency, radio service, configuration, and use. Use encryption only where lawful; encrypted mesh traffic must not be carried over amateur radio in violation of Part 97. Venue restrictions, safety rules, equipment review, and the Event Profile still apply.
Ordinary communications do not authorize electronic attacks. Electronic-operations scenarios still require written scope and isolated game devices. No personal systems or data, jamming, or disruption.
/ Radio rules
Good communication starts here.
Keep reserved channels clear
Channel 1 is for staff operations. Channel 2 connects players and staff, with emergency traffic taking priority. Neither is for team chatter.
Open channels are not private
Unencrypted traffic used during gameplay is not private. Share only operational information appropriate for the open event channel.
No jamming
Intentional interference, blocking, or disruption of event, staff, or emergency communications is prohibited.
Get electronic scenarios approved
Electronic-operations scenarios require advance approval, informed consent, strict isolation, and a defined end. No personal accounts, credentials, or data.
