Most Linux distributions package these files within the dtv-scan-tables or dvb-tools packages. Common locations include:

If your local transmitter recently changed frequencies, or your specific city/satellite is missing from the public repositories, you can manually build an initial file. Step 1: Gather Local Transponder Data

The most up-to-date files are maintained by the community at the LinuxTV dtv-scan-tables repository. You can clone this to get the latest frequencies for your city or satellite. How to Use the Initial File with dvbv5-scan dvbv5scan initial file

You can clone this to get the latest

| Issue | Likely Cause | Solution | |-------|--------------|----------| | No lock on any frequency | Wrong initial file (wrong region/delivery system) | Obtain correct initial file | | Only partial services found | NIT missing other transponders | Use -f to force full initial list | | AUTO parameters fail | Old or buggy demodulator firmware | Specify parameters explicitly | | Permission errors | User not in video group | sudo usermod -a -G video $USER |

: It accounts for local channel changes or "pirate" broadcasters that aren't listed in official frequency tables.
