You can't really fudge the wire used to
connect a tone panel to a repeater. I've
traced a number of noise and glitch problems
directly to standard and junk lead wire
used for tone panel connections.
Throw the junk wire out... go to the
www.radiowrench.com/sonic web page. Download
my msr 2000 to external controller squelch
gate mod. Within that text is the Motorola
Part number for their multi conductor wire
often found used for remotes and desk mics.
This is the black covered remote/mic lead wire,
which has the standard motorla color codes
used for their remote and mic connections.
About $1 /ft and it's the best investment in
wire you'll make for this type of application.
The contact info for motorola parts is also
included.
The key is the brown well shield cross wrapped
wire, which can be used for your low level
audio signal (ie descriminator audio).
You can easily see the difference with your
service monitor. You'd be surprised how much
differenc the type and quality of lead wire
can make.
cheers
