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
main changes from w_scan to w_scan2
- 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.

- The old behaviour can be enabled with -d
(--delete-duplicate-transponders).
- re-enable VHF band III in Europe
