Remarkably he starts loading an antenna and then deleting the elements to get a blank builder screen. The 4nec2 cannot start with a "new" file, it must load something from before. Only then I may select NEW. This is a bug. Well, there is no "new" button or choice under "File". Ask Arie Voors for the feature. It seems easy enough to add to the program. I copied the moves from the tutorial on my NEW antenna, and I cannot place a source on the dipole. Does not work. No error message, nothing. So I will load some old antenna, delete everything and try again as shown in the tutorial. Well, I've never had that problem because I don't try to "paint" the antenna using the isometric or 3D views. It's not accurate enough unless you snap to a grid. I create the antenna either externally, with a text editor, or using the spreadsheet style editor. I import that into 4NEC2 and make any necessary changes (and fix any screwups). For geometric shapes, I use the external shape generator, which will do surfaces, parabolic dishes, etc. 4NEC2 is not a drawing program. Within 5 minutes of work I have a list of 5 errors, program errors, repectively bugs, mis-leading the user. Impressive. You might want to search the 4NEC2 forums to see if any of them have been previously reported. http://fornectoo.freeforums.org Note that there is a section specifically for requesting new features. Can't type as fast as the bugs occur, I just described only one. Of course I have no right to complain because it's free. In my limited experience, people complain more about free software than paid software. That's usually because the author(s) encourage feedback in order to improve their product. Yeah. Thanks for ignoring my questions. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
