This gathering of RF radio engineers provides the most wonderful scholarship on figuring out how to make things happen.
RFB, your idea of feeding my window with a small capacitance worked! Now I have reached my first peak tuning with the AMT5k!
At first I used a 62 pF cap, and that opened the door on C1 actually causing my current readings to change. With the direct 4,000 pF from the window antenna those readings wouldn’t budge from one number. But the 62 pF would not peak.
So I got a 20 pF cap and on S5, tuning for 1550kHz, I knew something was happening because the current numbers started going through more changes in the shortest turns of C1 than they had with any other jumper. It hit a highest number and started to descend and I knew this was the payoff of the week. There was even enough room to turn one full time clockwise to get that special notch.
I’m going to put this on my job resume’.
