EM Scientific MININEC  ^pop - MININEC for Windows is antenna modeling tool for the novice, student and hobbyist.

ASAP - A Free general purpose antenna analysis user-oriented software program for numerical electromagnetic antenna design, antenna modeling and antenna analysis.

4NEC2 antenna modeler  ^pop - 4nec2 is a completely free Nec2, Nec4 and windows based tool for creating, viewing, optimizing and checking 2D and 3D style antenna geometry structures and generate, display and/or compare near/far-field radiation patterns for both the starting and experienced antenna modeler. Can be interfaced to HFwin32 propagation prediction software.

MultiNEC - MultiNEC can automate the repetitive steps of antenna modeling. You can start by building the model from scratch or by importing an existing model in any of several formats. Then you can run multiple test cases while letting the program make small changes to the model between runs. MultiNEC can be used by itself if you like, but it really shines when used in conjunction with your existing antenna modeling program. MultiNEC works with EZNEC Standard, EZNEC-M Pro, EZNEC/4 Pro, NEC-Win Plus+, NEC-Win Pro, GNEC, Antenna Model (Teri Software), and 4nec2

EMMCAP - EMMCAP is a user-oriented 3D Curved MoM software for the modeling of arbitrarily shaped wire structures and the computation of their electromagnetic behavior.

NEC-2 for MMANA - The utility "NEC-2 for MMANA" is intended for calculation of antenna models made and optimized in program MMANA and for construction and simulation of antenna models using input language NEC-2 and based on MMANA models.

MeteorSim - HSCW/WSJT meteorscatter/path simulator a first attempt at trying to model meteorscatter events and simulate their transmission characteristics

RDCP/Mac - RDCP/Mac is a communications software package to interface your Macintosh to models of Kantronics TNCs. RDCP/Mac uses the Kantronics HOST mode allowing simultaneous connections on VHF packet and the HF digital modes when using the KAM.

PPCMorse - PPCMorse and PPCMorse Pro are Morse code traning/sending utilities for PocketPC PDAs (such as the iPAQ, Jordana and Cassiopea).
