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.

That's probably when I last heard it! In fact not since I last used
valves and suffered from a rectifying contact in the socket.

All you'd hear today is a short databurst.

You'd be very lucky to hear that or would have to be in the taxi!..

Despite all the GPRS data they still use the voice radio to sort out all
the things that data messaging can't!..

You'd be surprised. Some time ago I made up 100v line XLR cables using
ordinary mains 2 core flex. Cheaper than screened cable. And found
one in use with a dynamic hand mic - because it was a nice shiny
white, rather than the more usual mic cable grey or black. And
apparently worked just fine. In other words it's the balancing that
gives the majority of the rejection of spurious stuff.


I'm told that Cat 5 Ethernet cable also works great for audio if you need
several channels, presumably because the pairs are tightly twisted. The
other advantage is that it is relatively cheap.






Yes it does its also very good for ordinary phone comms..

Open -wires were arranged that way. Two pairs on 4 insulators were rotated
90 degrees every so often forming a quad. But therse all went out of use
years ago, in overhead cables the pairs are twisted inside the cable.
