I wish I could! My vague memory is that Don Wilhelm pointed me to a couple of mods. A search of my emails didn't find any of Don's advice prior to 2017, and I think that is about 5 years short.
I suggest you google it, and check the Nabble archives. The mods were simple, changing a cap and perhaps a resistor value or something. The K1 is a great little rig. I built the 2- band version, and then the 4-band filter board, with all options. It still works like a champ. 73 Eric WD6DBM On Tue, Nov 30, 2021, 4:10 PM Douglas Hagerman via Elecraft < elecraft@mailman.qth.net> wrote: > Hi Eric. > > Can you be more specific about the mod that improved the KNB1?
