My past career was in Radio Telecomms, working for the Home Office to provide communications for the Emergency Services. VHF and UHF signals all over the place, using custom-made equipments.

During our final months before being "privatised" lock, stock, barrel and personnel to NTL, which had been a Civil Service arm, rumours started of the move from big radio networks, to modified use of the mobile phone networks.

That move happened so quickly that if you blinked, you would have thought that you had jumped into a very different parallel universe.

"What was" can change to "what is" so quickly these days, and I suspect that high power TV and radio transmissions are on their way out.
