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?

Thanks,

A Restricted Service License. Ofcom, the UK government Regulator for
Broadcasting, issues temporary licenses for special events. Typically they
are for 30 days in any one year, on FM, and usually power is limited to
25watts ERP or less.

Some RSLs, like our Hospital Radio Station are long-term, but we are
restricted to broadcasting to the local Hospital on AM, and are not allowed
to acknowledge on-air any listeners from outside the Hospital grounds that
may be listening to us. By going on the Internet, we can now acknowledge
outside listeners, but must be careful not to imply that they heard us on
1350.

RSLs are an expensive way to get on-air, as Ofcom charge a lot of money,
£2000 if I remember correctly for 30 days broadcasting a year or to a tiny
area.
