Considering that the radio's boards are pretested and aligned, causing smoke and pops would have to be an accident or intentional. I got my new V6 yesterday at the Post Office (DHL sent the radio from the Cincinnati hub by USPS to my Post Offic) and within an hour of opening the box, it was a working radio on my bench. No Problem. No smoke, no pops. Nor did I expect anything like this when turning on the power. It's a simple plug-n-chug operation to assemble ... as long as the assembler uses a metric scale to make sure to use the proper (short) screws to mount the complete case.
I assembled nearly all the ham radio Heath kits and only had one diode with the cathode band on the wrong end and a screw with no threads. With uBITX, I don't even expect to find this.
