It used to be simple for us - either unplug the aerial until you reach into the 50s, or unplug it after it gets to the 50s, during the tune. Our main transmitters all used frequencies up into the high 50s and 60s, while the local ones were all below 50(ish).

That was right PITA to deal with as it meant looking at the frequency for each of the channels (it just had BBC1, BBC1, BBC2, BBC2, and so on) and deleting the unwanted ones. In hindsight, might have been easier to pop an attenuator in while tuning - but I didn't have any back then.

Yep! Our most recent TV does that which is a godsend as we can pick up from three different 
transmitters: Hannington (BBC South Solent, which we want), Crystal Palace (off-beam but strong 
enough. London region obvs) and Oxford (Almost behind but close enough to register. Thames Valley 
local news).

The Youview Set Top Box which we currently use when we're not on myth, unfortunately does not :(. It 
has picked up a range of channels, some good, some terrible and I have no idea where from. The STB 
is a 'black box' and gives no clues at all. (The TV tuner on its own is useless.)
