PURPOSE:

To demonstrate the international reach of DMR.
To provide a Net for interaction with amateur radio operators outside local regions and specific interest groups.

In addition to hosting a Saturday TG91 worldwide net, an important goal is to support fellow amateurs, including newly licensed operators, by promoting good operating practice and constructive participation. Net Controllers aim to provide clear examples of effective on-air procedure, including correct use of the International Phonetic Alphabet.

TG91 IS NOT AN ENGLISH-ONLY TALK GROUP:

TG91 promotes worldwide participation. Operators are welcome regardless of native language, and reasonable effort is made to accommodate non-English speakers. Where language barriers exist, standard Q-codes and simple clarification are encouraged.

When appropriate and possible, Net Controllers may provide brief explanations in a participant’s own language to assist understanding of net flow and procedure.

INTERNATIONAL PHONETIC ALPHABET (IPA):

Accurate use of the International Phonetic Alphabet supports clarity, particularly for newer operators and during emergency or public service communication.

While variations are not prohibited, consistent use of standard IPA is encouraged to reduce confusion and improve accuracy during logging and message handling.

Worldwide Check-In Operation

The Worldwide Check-In operates as a structured, region-by-region net coordinated by Net Control.

Typical calling order includes:

• Asia and Pacific
• Middle East
• Europe
• Africa, Caribbean, Latin America
• North America

Stations are requested to check in when their region is called or during designated late or missed check-in periods.

This is a controlled net. All traffic is directed through Net Control, and read-backs are used to confirm successful check-ins.

History

The Worldwide Check-In began in 2015 following the expansion of DMR repeaters on the BrandMeister network. It was founded by Dick K6SUU and later supported by additional volunteers as participation grew.
