increase in noise on any band when I connect an antenna. Tracing from the antenna jack toward the mixer, I get a good increase in noise when I touch the antenna to the junction of L6 and the RF gain pot. On the antenna side of L6, there's no increase in noise. Rereading the assembly instructions, the manual says to connect A on the KXB3080 to B on the KX1, and B on the KXB3080 to A on the KX1, because the markings for A and B on the KX1 are incorrect. But if this is the case, why was the KXB30 connected A to A and B to B? I'm wondering if this is my problem... ------------------- No. You have it right. Those marks on the KX1 PCB are correct for the KXB30 and incorrect for the KXB3080. I suspect L6 is open. Have you ohmmed it? You moved L6 to the underside of the KX1 PCB as part of the KXB3080 install. Is it in the right holes on the bottom? You should see about 1 k ohm from L6 to ground with the RF gain at minimum on either end of the inductor. With the RF gain at maximum, it should show about 1 to 2 ohms to ground. The inductor itself has a DC resistance of about 1 ohm so it'll be about 1 ohm higher from one end than the other.
