Editing a Mux or adding a channel - Solved

For a basic user, my Muxes (Mendip UK) work fine except it leaves out 586MHz (Ch 35) and thus 7 stations. I also have tried using the --Generic--: auto-Default Mux setting but it also leaves out 586MHz and these 7 stations.
I've also tried Configuration - Channel/EPG - Channels - Add but whatever I try, I cannot add 586MHz or just one of the stations. (My ordinary TV does pick up these stations, over the air.)

I've tried following the advice of Peter Maersk-Moller in [[https://tvheadend.org/boards/5/topics/41748?r=41756#message-41756]]

He suggested changing
/usr/share/tvheadend/data/dvb-scan/dvb-t
but my data directory has no dvb-scan folder

Has anyone any ideas as what to try next? I'm a fairly simple user, not a coder.

Update: I looked at TVHeadEnd on my Debian 9 Atom computer and the dvb-scan folder does exist. By editing this file and adding the missing Channel 35 mux, I've regained the missing TV Channels. I had to play around with the settings somewhat to get a working version.

make muxes manually in interface do not change source code of program.

install dvb-apps and dtv-scan-tables

Thanks saen acro, but do you mean the web interface? I thought I tried all sorts of things in the web interface, EDIT: even creating a MUX (586MHZ) but couldn't see a way of using this amended mux list in a scan. Each time I carried out a scan, that newly created MUX disappeared.

I added the following to the Mendip UK Mux, and I got back the channels I wanted, but somehow have messed up the EPG, because I have little idea what all the lines mean. Great learning curve though.

# new channel 35 [C35 BBC B] DELIVERY_SYSTEM = DVBT FREQUENCY = 586000000 BANDWIDTH_HZ = 8000000 CODE_RATE_HP = 3/4 CODE_RATE_LP = NONE MODULATION = QAM/64 TRANSMISSION_MODE = 8K GUARD_INTERVAL = 1/32 HIERARCHY = NONE INVERSION = AUTO

All is sorted now, running and recording properly. I found messing with the muxes was problematic, but then found that Linux TV has more up to date muxes at:

https://linuxtv.org/downloads/dtv-scan-tables/dtv-scan-tables-LATEST.tar.bz2

On the RPi, unlike a Debian 9 install, the tables are located at:

/usr/share/dvb/

I replaced the whole of the dvb-t directory although I noticed that a new install of TVHeadEnd, on the RPI, had a more up-to-date Mux for Mendip-UK, including the missing channel 35 (edit - 65!) , 586 MHz.

Hope this is useful to some RPi user, left behind by frequency changes. Our next frequency change was due on June 22nd, but has been postponed until a later date, not yet known.
