'Should' is quite right! I have looked, and relooked, (shows everything but the damn frequency!) I have also looked on other Freeview sites for the UK, and only have found COM4 Mux and COM mux frequency details and these corespond to what the HDHomerun is stating.
This 700MHZ clearance for 5G mobile has been handled badly, (didn't know anything about until I switched on Kodi, and went to BBC1 and got zip, did though get a shopping channel!), as I can only find information on what it was, and there is nothing on those frequencies hence that TVH correctly is reporting nothing on those MUX's. I can find the frequencies easily for last week (before retune!) but not AFTER!
This is why I stated that it isn't an issue or bug as TVH is working perfectly well. From what research I have done so far in finding these, and resorting to my setup as a guide (not ideal, but there we go!) I feel I can do this easily, it's only changing the frequencies etc on an already made file.
I just now need to test these out, I know what to change, I have already have a GitHub account and already made my own folk, I now just need to know how to merge the TVH and DVB-Tables repos to make a working local copy on my Ubuntu instance. This is the first time I have used Github, thankfully Nate from Team Kodi put a good overview last week on how Github is used, and took the mystery of modifying and editing code to a FOSS project. I have pull reuqests and commits nailed, as I have already tested that out so this is the final piece in the puzzle to actually do something for FOSS.
Once tested I shall then hopefully send the PR and commits, as I have now realised that the Guildford transmitter covers a wide area and is the 'local' relay for Crystal Palace. I am assuming then that Crystal Palace is suffering the same, and if so I can edit those files too if need be. I do realise that these DVB tables are only updated by contributors around the world, and are probably only updated when things like this happen.
Like I said earlier, just need a pointer, like before, and I should be able to nail this very shortly.
