Программа Briana K6STI под Windows позволяет рассчитывать ДВ-СДВ катушки из обычного провода и литцендрата, определять добротность, оптимизировать размеры.

I've updated my coil inductance and Q calculator to handle VLF loading
coils. I replaced the HF approximation for skin effect with a
calculation accurate at any frequency. The proximity effect calculation
also now makes sense at low frequencies.
The program calculates inductance and Q for solenoids made of solid or
Litz wire. It handles a number of wire alloys and form dielectrics. It
models dielectric ribs, ridges, or grooves, axial or radial leads,
polygonal coil shapes, and can use U.S. or metric units. The program can
automatically maximize coil Q while keeping inductance constant. It can
provide results as an RLC model for wideband circuit or antenna analysis.
To validate accuracy, the documentation compares calculated values with
hundreds of inductance and Q measurements made on dozens of coils of
widely varying size and shape. For the coils from my own junkbox,
average error magnitude is 2% for inductance and 5% for Q compared with
measurements I made with an HP 4342A Q meter.
The program runs in Windows and is free.
