it's been a day so I'll ask again: w_scan doesn't find any DVB-T/2 HD channels that I know are there. there is no file in /usr/share/dvb/dvb-t/uk-* that matches my region. given just the info from digitaluk.co.uk that matches my postcode, how can I get the FREQUENCY and BANDWIDTH_HZ values to create a new file, to then scan with dvbv5-scan?
If you have the channel nos., you can get the frequencies easily enough – use tables or a simple formula.
Bandwidth is always 8MHz.
