Chuck, KI4DGH asked: I have just finished Part I Modify the KX1 PCB section and now I am attempting the steps for Alignment and Test -Part II for receiver alignment to confirm that the modifications have been correctly installed. Obviously I messed something up. Nothing happens during power up. I get power up to the power switch but when I turn on the switch nothing happens, no LED no relays clicking nothing. I had a KXB30 installed and completely removed the KXB30 board and all wires. I would really appreciate some help troubleshooting this problem.
------------------------------------------------------------- Do you have a metal screw holding the final amplifier mounting hardware together, Chuck? If you put a metal screw in the final amp without the heat sink, you're shorting the B+ to ground! Right off hand that's all I can think of at this point. All you've done is remove the KXB30 module and reconfigure the receiver input circuit. That doesn't involve any direct connections to the B+ circuitry. If it's not the 'screw in the final amplifier' bit (which probably half of the KX1 owners have done with the unit open, including me!) I'd look very closely for a solder bridge somewhere around the components you just replaced or the transformer you added.
