I am at the first power on test stage of K2 # 6281 and have anomalous readings. Should be INFO 250 or 7100.0 c What I get is ELECrAFT followed a few seconds later by 0 ? 50.0 c (or u,r,etc) Turning VFO dial does not change frequencies as expected but changes to 1 5 15.1 and other strangeness. After that I can hit DISP and read normal voltages. Power display works when power adjusted, keyer speed adjusts ok. RIT/XIT is adjustable but the range is like 23253 +/-. So, many things work correctly for a rig that's only partially built, and other things are incoherent. I can access menus and use edit. Most things are OK but no frequency display that makes sense. Component value and placements checked and rechecked and all solder connections reflowed. MCU chips 1.09 and 2.04 swapped with working K2 and replaced with no indication of fault. Due to all the playing around with the FP and Control Board I am suspicious that the eeprom may have been exposed to some random resetting that is confusing the issues. Does anyone have a 'reset to default' procedure that might take us back to the starting point? Anyone else ever see this kind of behaviour? I have half a dozen highschoolers who are afraid they have broke the pooch but I can find no visible signs of an error. ESD practices were scrupulously adhered to and swapping parts with a working K2 hasn't uncovered anything, so far. 73, Al WA6VNN
