If you can't make them work then I would forget about computor
programs.
They obviously are not your cup of tea despite how many people use
them with success. You would be better off finding out what you are
doing wrong than sending money at the problem.

Hi Art,
do you mean that NEC-2 works fine even with D1 very close to DE?
Other reasons for buying NEC-4 would be obtaining useful results with wires
near ground and connected wires with different diameters.
Thanks and 73
