w_scan2 is a small channel scan tool which generates ATSC, DVB-C, DVB-S/S2 and DVB-T/T2 channels.conf files.
It's based on the old "scan" tool from linuxtv-dvb-apps-1.1.0. The differences are:
- no initial tuning data needed, because scanning without this data is exactly what a scan tool like this should do
- it detects automatically which DVB/ATSC card to use
- much more output formats, interfacing to other dtv software.
w_scan2 is a fork of the original w_scan from https://www.gen2vdr.de/wirbel/w_scan/index2.html
-
keep duplicate transponders by default because a stronger transponder with the same ID might have a higher frequency and be discarded simply because it's scanned later. Also don't replace the current transponder with an advertised one by default. The latter may have a lower signal strength. More details here: https://stefantalpalaru.wordpress.com/2016/02/04/scan-all-the-things/ . The old behaviour can be enabled with -d (--delete-duplicate-transponders).

NOTE: Newer versions of w_scan2 need the '-c' option for specifying the country (ATSC, DVB-C and DVB-T) or '-s' for satellite (DVB-S).
