I am at the Alignment and Test - Part I portion of constructing the K1. All of the tests went GREAT up to the part about Band-Pass Filter Alignment (page 40). With the antenna connected, I hear only white noise through the headphones. Adjustment of the slug-tuned inductors does nothing. Connecting and disconnecting my antenna wire doesn't even make a crackle. I ran the checks in the back of the manual with my RF probe under "Receiver and VFO Signal Tracing" (appendix E pages 5-6). My input voltage with the battery pack was about 11.5 volts. Here were the results for the numbered tests under that section: step 5: .02 V - OKstep 6: .222 V - OKstep 7: .025 V - a bit lowstep 8: 0 volts - fail. All steps after #8 that failed, as well. I suppose there is something wrong in the premix band-pass filter, but am not sure where to go from there to narrow the problem. Again, any help is appreciated.
