I've just installed an ICOM 802 in my boat and today found that the only way
to get clean noise-free weatherfax reception on my Sony VAIO laptop is to
disconnect the "power brick" and run the laptop on batteries alone.

===================================

Are you running the power brick from a small inverter? If so, that is
more likely to be the noise source in my experience. Try running the
laptop on shore power while at a dock and see if you have the same
problem. If not, consider getting a better inverter. My Xantrex
Prosine generates very little RF noise compared to the small modified
sine wave units.
