Hallo Elecrafters, last afternoon I went through KX1 receiver alignment but the results were disappointing.
Not having a signal generator, I connected the KX1 to my W3DZZ. By turning the capacitance trimmers, I could peak band noise, but could barely hear the strongest signal on the bands, although I could hear several good signals on both 20 and 40m when switching to my K1, which should have about the same sensitivity. Checked L1 and L2 with a DVM: both were < 1ohm; tried to inject a signal into the path from the antenna jack to CA/L6/R1/CB/L7 by touching with a wire and couldn't find any interruption. Voltages on the pins of U4,U5,U6, Q2/Q3 agree with the manual. I measured the voltage on the base of Q7 and found -0.4V, which is funny as R28 is floating (R26 not in place yet) and I can't understand why it should have a negative voltage. Anybody out there who had the same problem or could give me a hint? Any suggestion is welcome. Tnx es 73 de Pier, IK1RDN K2 s/n 4104 K1 s/n 1975 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
