Just out of curiosity and as I did not like the looks of it, I re-did the T2 trifiliar :) Numbers grew a little bit on the Y axis of the graph but almost no change at all on the filter shape I see on RF sweep. As a next step I will probably re-do the LPF's of 20/30m. For getting a decent output I had to squeze them a lot? anyway when I was doing the first tests. Which also tells me something maybe wrong with them. Also when I was winding them I measured them with my cheap Chinese Lcr meter and readings was a little bit off but I decided to stick to the number of windings in manual as I don't trust that lcr meter too much. As I'm pushing my luck and soldering skills a lot on this, I'll probably first wait for the weekend to at least enjoy a few more Qso's with QDX before I probably ruin some pads on the board while experimenting :) I deeply regret that I did not order two QDX's (one for using one for experimenting..)
