Thanks for all the pointers.? I went ahead and added the tantalum capacitor.? More filtering is always good, right?? Also, for some reason my regulator had the center pin clipped.? Since the heatsink tab on the QCX isn't connected to the ground plane I had to create a makeshift extension to the center pin.? Otherwise, all went smoothly, and the radio is operating well.? Now all I have to do is learn CW, lol.?
