[TowerTalk] Transition from AO to EZNEC

And just to add to the confusion, there is a shareware Excel front end for NEC-2 or 4 that is written by Dan Maguire, AC6LA (www.qsl.net/ac6la).  It is much easier to use than 4NEC2, though not as powerful.  A full-capability demo is available.  One great strength is that it translates to/from EZNEC file format, and has a tight integration to VOACAP.  No optimizer, but excellent variable handling and a multi-iteration test-case generator.  Uses 4NEC2's visualizer.
