That is too bad, you would think these could be kept active for historical purposes. But seems these services are all being turned off even though I heard a few were very useful in this day and age.

IIRC, their operation relies on enormous vacuum tubes that the BBC can’t get replacements for any more.
In some way it is short-sited, as radio is a good backup medium for global communications in case the entire Internet ever goes down.

Vacuum tubes also aren't vulnerable to nuclear weapon electro-magnetic pulses.

However, other than ham radio enthusiasts I guess no one listens to analogue radio anymore.
