Does anyone know where I can get a copy of the NEC antenna analysis source code? I have a fiche copy of the MININEC Basic code, but that's pretty useless to me. I believe that NEC, from which MININEC was derived, is written in Fortran and is in the public domain. I will post any relevent information I receive, so please no "send me a copy"'s. <<< Len Saaf saaf@joker.optics.rochester.edu >>>

The last time I checked, the NEC was available from the National Technical Information Service (NTIS). While the code available from the NTIS is in the public domain, you cannot distribute what you obtain from them in the form that they supply it. This is a rather strange statement and is subject to some likewise strange interpretation. Rusty's callsign project was an example of this - all of the FCC callsign and address information for amateurs is available from the NTIS. Rusty wanted to create a computer callbook from this information. Before he could distribute his "electronic callbook", he had to extensively massage the data "so it was not in the same form" as it was obtained from the NTIS. I am not sure how this would be handled in the form of programs. You could certainly use the NEC program for personal use, but I do not see how you could distribute it further. BTW, the last time I checked, the NEC was over $1600 to get a machine readable copy from the NTIS (standard 9-track IBM tape). If you re-wrote the program in C, you could probably get away with distributing it. Heck, you could probably sell it! ;-) Don't pass over MININEC so easily. It is quite acceptable for very many applications. Data entry is easier than the NEC and when using compiled BASIC, the speed is not so bad. It is also available from the NTIS in machine readable form - over $400, I think. There are a number of companies that offer programs based on MINENEC that have graphical outputs and easier data entry still. Many of these sell for less than $100; you can often find these advertized for sale in many ham radio magazines (QST, Ham Radio). I hope this information helps. Good luck. 73 de WA4VZQ, Barry ----------------- | ___ ________ | | | / / | | Dr. Barry L.
