KSKelvin,
I mistakenly tried to respond to your 2 replies by email but got 2 send errors. So, I’ll thank you again for providing these great detailed responses about extracting S-Parameters in QSpice. I’ve tried both methods and chose the method you and Frank provided with the simple Pi filter. Works like a charm.
I too use SimSmith (now SimNEC) since 2013 and have successfully simulated my same filters.
