John,
you could use SIMetrix (www.simetrix.co.uk) but it might be a bit overshoot.
Anyway, they have a free (and very useful) demo version.

Onderwerp: LF: Circuit Analysis Programs
I am experimenting with various forms of matching network to go between my
136kHz antenna and the transmitter. It would be very handy if I had a fairly
simple circuit analysis program with which to do the following:
Having measured the input impedance to the combined matching unit and antenna,
then “subtract” the components of the matching network, see what I get and
compare it with what I actually measure. I'm not always convinced that what I
measure is what I think I'm measuring.
Platforms available: XP, Linux and MacOs X.
Yes, I could write something, but somebody must have done this and there is no
point in reinventing the wheel.
Any suggestions, please?
Regards
John F5VLF
