Larry,
Do you have ferite beads at both ends of all your NMEA cables? If so, do
they help?

I tried that, too. They reduce the noise, somewhat, but the open screw
terminals on the Noland multiplexer, the unbalanced lines making all the
unshielded NMEA cables into a giant transmitting antenna just bypass them
beads or clamshell ferrites so much it's nearly useless.....

I bought a new Maxtor 300 GB external portable hard drive for my system,
today, in a moment of weakness at Best Buy ($299). It came with the nicest
WELL SHIELDED USB-2 and Firewire cables with clear plastic coverings so you
can see the braided shield inside....oh, the longing for a whole boat
network like that...(c;
