Let’s start with the website ham-digital.org. It contains the user database of registered DMR-IDs worldwide.
ham-digital.orgis dead and the european database has been put together on radioid.net.
Are you still waiting for your confirmation email? You may
look at the registration site, which contains links to the list of open
registrations or the list of local administrators.
Okay, I try to keep this simple. These scripts are made to download an actual snapshot of the DMR-ID database from ham-digital.org. They create a comma-separated list of DMR-IDs and callsigns to import into an amateur radio device. Actually I use them only on my Radioddity GD-77.
Download the full database
That fetches the whole database, which are something around 180.000 entries at the moment (2020-Nov-15). The script uses about 8MB of RAM. Something like that.
Download only a few regions into separate files
Fetch some regions (specified in the script) and some additional callsigns from a file that contains one callsign per line. This script uses a lot more RAM. Something around 32MB I guess. Or so.
Download only a few regions into one single file
Like the one above, but it saves all IDs into one file. Uses probably the same amount of RAM.
