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

Yes, I have been told this before. I have also been told that if, for example, the UK is subject to a nuclear attack, our armed forces outside the country wait until 6AM to see if the 'Today' programme starts on Radio 4. If it doesn't, they have to assume that the country has been severely, severely damaged or obliterated (serious). Maybe some of our ex forces members would know?
This is why I wondered if VM took any special measures to keep Radio 4 on air.
Also (I may have got this wrong), but ISTR that the BBC wanted to close down the Radio 4 LW service as part of their cuts due to the licence fee freeze and because the valves were getting increasingly hard to source. Perhaps the threat of a nuclear attack is now considered unlikely- but what about the stations time reference function??

What would you hear if you tuned to this frequency?

Lol, if they did this, Challenge +1 would still be off air as it would be taken over by the Emergency Broadcasting Service.
If it becomes apparent that the world is about to end and any VM customers are watching channel 607- this is what you'll see!
