[net.micro.cbm] VIV Audio/Video Quality Problems

When I connect my C64 to a TV set via the TV/computer
switch supplied by Commodore, the noise is so great
that is literally no picture at all.
	I have found that by connecting a wire in
the range of 3 to 4 feet in length to the case of
the switch the noise almost goes away.  As far
as I can tell, there is no electrical connection
between the incoming and outgoing leads to the
switch.  Therefore, the wire must be acting as
some form of inductively or capacitively coupled
trap.  That is as far as I've analysed the problem.
	 Experiment with the length of the wire to
optimize the reception.
