Things are beginning to look a bit more like a LPF with the "ground"
connected! Other suggestions have been made which are right on. Keep us
posted on your progress.

Dave,
Thank you for your reply. Very much appreciated.
In order:
1) Done.
2) Yes, I measured all components with my LCR meter (DE 5000).
3) Correct. 50 ohms confirmed by others for this filter.
4) It's possible that some capacitors aren't right for this frequency
range. I'll look into that.
5) I posted the S21 imaged from the VNA, not the SAVER program. I'll work
on that next.
6) Signal generator does not sweep; that's a good idea and will try to
figure something out.
Thanks for your help. I'll spend most of tomorrow working on this. Best,
Mitch NK3H
