How do I full scan all terestrial channels including scrambled

[ALIEN1X]

Given that the Topfield wouldn't pick up any DVB-T2 channels, you'll have more here. And yes, ~170 sounds right.
Of course, if you haven't retuned the Topfield in the last few years and removed old channels there may well be some there that you will no longer find. TopUp TV?

Many thanks for the feed back. I have 3 DVBT2 tuners installed Tuner A I can scan in approx 170 channels but tuner B and C can onlyu scan in approx 140 or less channels. Any tips on how I can get all the tuuners the same number of channels up to 170?

Also arrived today is a sat tuner S2 plug in module, once fitted how do I switch between saterlight and terrestrial EPG and will the sat tuner automacticall self tune or do I have to go into USALS SET UP?
