Indeed it is .. we once used around three miles of phone cable overhead

very quiet indeed..

I was once told that the cables on telephone posts are arranged to
form a twisted pair. (I.e. the cables move from insulator to
insulator so that they twist around each other.)

Pardon my ignorance, but what is an RSL?


I presume he's talking about a Restricted Service License. This would
be something like a special temporary FM transmitter serving an event
(the British Grand Prix will certainly have one next month).

It would need a signal feed from a studio somewhere.
