Re: Does VM protect BBC1 and Radio 4 above all other on the network?

I was thinking that cable would be more resilient as it is mostly underground, but you're right it isn't really.
Two reasons that I know of:

1. It is used as a time reference by a lot of test equipment. It is atomic controlled for frequency.

2. IIRC our nuclear subs monitor it, LW propagates well around the globe, and if it goes off air then they go to alert status.

It is also relatively easy to fabricate a receiver for the signal from odds and sods, unlike DAB, or FM.
