Hi Phil,
Could you please share your experience on peaking the BPF on 40m. Your T1 looks neat, did you need to remove turns on the bigger coil? Your C1 looks FB.
Is it a sharp peak? My QCX works but I'm concerned about the BPF in general, I don't get a sharp peak and had to remove 5 turns with C1 fully unmeshed on max....
