As far as I can work out, if you want radio reception in the remote parts of the UK Highlands then you are out of luck - unless you like Radio 4 and have a long wave receiver.
As it happens, I like Radio 4, but I don't have a long wave receiver. These aren't made anymore, which is fair enough given that Radio 4 is the only station broadcast in the UK and that will go offline as soon as the next ancient valve breaks.
But what happens if you want to go hiking away from it all except for a bit of news?
Well, a ferrite rod, quite a few turns of copper wire, a capacitor and a three leg amplifier may work - I'll update if it does…
