MM7DBT Codeplug Editor

There is a section of the .json file for the Radioditty DB-25D Pro that is labeled "DMR channels" (not to be confused with Zones/Channels). I have not found it discussed in any of the DB25D Pro or CPEditor documentation. What is it and how is it created? I don't see anywhere that they are input so are they automatically created by the editor? Thanks for explanation/help.

"DMR channels" comes under the "APRS" section.

These are the 8 Digital APRS Channels found under the APRS tab.
