Re: Twin co-ax outlets

[phil.hooker@xxxxxxx]

The socket I was using is a twin outlet from Maplins. If I just connect one
of my cables it works fine. If I bring the other cable near to the
connecting block the interference starts, even though it is not touching.
It seems to be the cable ends being near each other that causes the
problem. I went into B+Q to see what outlets they had and noticed in small
print on the back of the box that they were unsuitable for seperate
sources! Well what is the point of a twin outlet that must have the same
source!
