I would also like to see radar on the pc?

There's only a few ways available to you in getting a full radar display
on your PC, and NMEA ain't it...

1) Koden (resold by Nobeltec, SciTex)
2) Furuno + Maxsea
3) Raytech with HSB-2 interface

You can get MARPA targets and a lollipop transferred thru NMEA, but
that's probably not what you're looking for.

For now, given your self-proclaimed info overload, I would forget about
this.
