| Right! And qucsStudio is Windows only, I believe.

| Qucs runs on Linux, MacOS, and Windows.

| Also to be clear, Qucs helped me a lot when I was searching

| As both are good projects, and one is the foundation of the
| other, I think both deserve some credit and support.

| What does this offer over say LT-Spice?

| Good for RF sims. It's free compared to ADS which is NOT.

| You _can_ use LTSPICE for some kinds of e.g. transmission line
| models but it doesn 't have things like the Smith chart built

|
| You also _can_ use Qucs for modeling things you 'd normally use
| SPICE for but the library isn't there, so it's not worth the
| trouble.
|
| Basically, two different tools for completely different sets of
| problems.
