World Wide Check-In (WWCI) is an international amateur radio net conducted via Digital Mobile Radio (DMR) on Talk Group 91 of the BrandMeister network.[1][2] Founded in 2015 by amateur radio operator Richard D. Decker (K6SUU), the net provides licensed amateur radio operators with a structured environment for making worldwide contacts, exchanging signal reports, and participating in organised net operations.[1][3] The net takes place every Saturday at 16:00 UTC and attracts participants from multiple countries and continents.[1][4] HistoryThe World Wide Check-In was established in 2015 to provide amateur radio operators with a regular opportunity to communicate with stations worldwide using digital voice technology.[1][3] The growth of internet-connected repeater systems, personal hotspots and the BrandMeister DMR network enabled participation from operators located across North America, South America, Europe, Africa, Asia and Oceania.[1][2] The BrandMeister worldwide net on Talk Group 91 has been documented in amateur radio net listings since at least 2017.[5] As participation increased, dedicated logging systems and multiple Net Control Operators (NCOs) were introduced to support the growing number of check-ins and maintain efficient net operations.[1] PurposeThe stated purpose of the World Wide Check-In is to demonstrate the operation and capability of DMR, bring together radio operators from around the world, and show how a globally linked amateur radio network operates.[1][2] The net also provides operating experience for licensed amateur radio operators and promotes international communication within the amateur radio community.[4] OperationsThe World Wide Check-In is managed by one or more Net Control Operators who coordinate check-ins, maintain operating discipline and record participating stations.[1] Typical net operations include:
During extended sessions, control of the net may be transferred between multiple Net Control Operators to ensure continuity of operations.[1][3] Technical format
Operators may participate using DMR handheld transceivers, DMR mobile radios, fixed-base stations, personal hotspots, or internet-connected DMR gateways.[1][4] ParticipationParticipation is open to licensed amateur radio operators operating in accordance with the regulations of their respective licensing authorities.[1] Stations may participate through repeaters, personal hotspots and approved network access methods connected to the BrandMeister network.[1][2] Participants represent multiple countries and regions worldwide.[1][4] The net regularly records several hundred unique check-ins during a single operating session.[1] Net loggingA dedicated digital logging platform is used to record participating stations and generate operational statistics.[6] Published logs may include call signs, DMR IDs, countries, check-in times, net duration, participation totals and operational remarks.[6] Historical logs are maintained as an archive of participation data and net activity.[6] Community impactThe World Wide Check-In provides a platform for international amateur radio communication, operating practice and technical experimentation using DMR.[1][2] The net enables operators from different countries and backgrounds to communicate regularly and share experiences relating to amateur radio, digital communications and station operation.[4][3] SignificanceThe World Wide Check-In has operated as a weekly amateur radio net since 2015.[1][3] The net has been documented by multiple amateur radio publications, directories and community resources, including ICQ Podcast, NetFinder Radio, RadioID, HamNetList and other DMR-related publications.[3][4][7][8] Published net logs document participation exceeding 600 stations during some operating sessions.[9] See alsoReferences
