Does anyone know how to change the distance from the source (R) at which 
far-field calculations are done in EZNEC?  Yes, I know I can scale the results 
by scaling with e^(-jkR)/R, but it’s tedious to calculate each time I want to 
change R.

I have gone through the manual a few times now, and the only values are either 
one mile or one km. The NEC RP card lets you make the change, so I know that 
Roy must be setting the parameter (or maybe not).  

Apparently, Roy isn’t answering questions on his website anymore.

Finally, I know I can export the 1 km numbers to Excel or MATLAB and do the 
calculations, but it’s much easier to do them in EZNEC. I guess I can just run 
NEC5 with cards, too, but again, it’s easy with EZNEC.

Thanks for reading,

73, Jeff
