WoketWabbit:

Another method that has worked well for me is the use of RG-179 coax. Leave the power and ground wires alone, run the signal only through the '179. As Mike said, in post #2, tie the shield to ground (negative batt lead) only at the rx end.

Advantage is it's lighter than the 3-cond shielded, and you eliminate the possibility of cross talk through the positive lead.

Crosstalk and RFI cause glitches,
. and they're nasty little sons-a-b.........
