I want to be able to quickly scan for changes/new channels on DVB-C/S/S2/T2
using the CLI over SSH and "DVBlast and w_scan tools" or others
rather that going through the MENU on the TV, since I have quite few tuners always available.
I have 3 cards for Cable, Sat and Terrestrial.
Tuner A Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner B Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner C Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner D Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner E Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner F Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner G Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner H Vuplus DVB-C NIM(BCM3148) (DVB-C) Tuner I Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner J Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner K Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner L Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner M Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner N Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner O Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner P Vuplus DVB-S NIM(45208 FBC) (DVB-S2) Tuner Q Vuplus DVB-T NIM(TT3L10) (MultiType DVB-C/T2) Tuner R Vuplus DVB-C NIM(TT3L10) (MultiType DVB-C/T2)
Is it safe to assume that the tuners are as follows?

Version of DVBlast on the Vu+ box is 3.4 (git-3.4-14-g4270dca-dirty).
Version of w_scan is 20170107.
I know that the Cable opp is using the following:
Symbol rate: 6900
DVB-C
QAM256

#w_scan

Checking on the manual:
https://manpages.ubu...1/w_scan.1.html
I try following:

But the scan finds nothing:

So I know working multiplexes and trying DVBlast to see if I can see anything on specific mux in SDT and run following command:
dvblast -f 498000000 -s 6900000 -a 0 -n 6 -5 dvbc_annex_a -m qam_256 -f --frequency frontend frequency -s --symbol-rate -a --adapter read packets from a Linux-DVB adapter (typically 0-n) -n --frontend-number <frontend number> -5 --delsys delivery system DVBS|DVBS2|DVBC_ANNEX_A|DVBT|DVBT2|ATSC|ISDBT|DVBC_ANNEX_B(ATSC-C/QAMB) (default guessed) -m --modulation Modulation type
But it would lock/scan the "last tuned" multiplex rather then 498MHz ....
Anyone any idea, where I am going wrong?
