[VHFcontesting] RF Filter analysis software

[K3SK at buckwalter.co]

Does anyone know of a software package or web site that I can use to do RF
filter analysis?   I am looking for something where I can input values of a
filter and see/analyze the bandpass/cutoff characteristics.   There are
plenty of sites where I can design filters by inputting freq/type, etc and
it will calculate values (markimicrowave.com), but I want to do the
opposite.    I have the values and want to see what it looks like.
