With this file, dvbv5scan will attempt each frequency sequentially, quickly building a complete channel list. Once you have a working initial file, you can script channel scans via cron. For example, to rescan every Sunday at 3 AM:
Example: For a standard Universal LNB (LOF Low: 9750 MHz, LOF High: 10600 MHz), if your satellite transponder is at 11.8 GHz: 11800 - 9750 = 2050 MHz . So FREQUENCY = 2050000000 Hz. Even with a perfect initial file, if your antenna is disconnected or misaligned, scanning fails. Check signal using: dvbv5scan initial file
dvbv5scan -a <adapter_number> -f <frontend_number> However, when you run this command without proper preparation, you might see: With this file, dvbv5scan will attempt each frequency
