Re: [amsat-bb] EZNEC model

Bob,

I can do that with Nec4win95.  I have the enhanced virtual memory vers.
that utilizes the HD for expanded memory.  If you want I could take a run
at it.

PS:  I did that for my first tracking buoy: 1/4 wave whip on a 6-in dia by
12-inch long cylinder buoy.  Took a lot of matrix building but ran and did
a fair model of the real thing.  Curent buoy is off-center whip on 18-inch
dia by 8-inch cylinder...antenna match was so easy that I haven't made a
model.  I probably will to get a look at the pattern.
