I have a problem when running w_scan2. I use:

w_scan2 -X -c GB

But i get error:

w_scan2 -X -c GB w_scan2-1.0.13 (compiled for DVB API 5.10) https://github.com/stefantalpalaru/w_scan2

using settings for UNITED KINGDOM DVB aerial DVB-T GB scan type TERRESTRIAL, delivery system SYS_UNDEFINED, channellist 6 output format czap/tzap/szap/xine WARNING: could not guess your codepage. Falling back to 'UTF-8' output charset 'UTF-8', use -C to override Info: using DVB adapter auto detection. main:4776: FATAL: NO USEABLE TERRESTRIAL CARD FOUND. Please check wether dvb driver is loaded and verify that no dvb application (i.e. vdr) is running.

I try with three different usb adapters, but all same result.

When I run:

lsusb

it list whichever device is usb inserted

also

dmesg

it also displays device

System: Ubuntu 18.04 Nvidia Jetson Nano

devices used: RTL-SDR - Realtek Semiconductor Corp. RTL2838 DVB-T Mirics msi001 / msi2500 Airspy mini - Rafael Micro R820T2 R860

I am able to use all three devices with SDR software such as gqrx/cubicsdr/sdr++

The problem is not with w_scan2. You need kernel drivers (and sometimes firmware) for these sticks to work for DVB-T/DVB-T2. See:

Thank you for reply :) Please can you tell do you know if you have seen working drivers used for any of my three USB devices?

I have Me-TV and W_Scan2 Compiled on my Jetson Nano Arm computer and i would like to scan for DVB-T / DVBT2 UK Freeview as first test, then try other things later.
