It's quite amazing what you can bend LTspice into doing (microwave stuff? Speaker development?)

It's worth persevering with Martin. There's a bit of a step at the beginning, but from then onward the learning slope is reasonable, and you start to be able to use it to do things. This gives you a firm foundation so you can go further as you wish.

If you learn a lighter simulator, you soon run into its limitations and have to dump it to start again on something more capable. Instead of several dead-ends, just go for one that goes all the way.

Various semi manufacturers have their own sim software available. Some of it a bit crippled, some of it only available in their cloud via alive webpage, and some of it is pretty good. LT pice is one of the best and is a full blooded spice variant into which you can bring other spice models and twiddle them into working. Very much in the spirit of Jim Williams. I suspect he had a hand in it.
