I have heard USCG wx broadcasts on 8764 from Pt Reyes (NMC).
In the link posted above by "dave3825" you may find the schedules and frequencides for Marine Weather Broadcasts from the USCG.
NMC anymore is a hard station for me to get. I bounce around between NMF, NMG, NOJ, rarely KVM70.
I scan all the frequencies with my Barrett and stop on navtex and wefax.
I get voice sometimes from New Orleans or Honolulu.
