I put together my BITX40 and tried to calibrate the Raduino. While tuning it in calibration mode, it suddenly began to make a loud noise that sounds like the clicking sound when you turn the pot, but it was not clicking but only making a continous sound. I had to remove the battery to get it stopped. After that, the display just gets lit but did not show anything. I tried to reprogram the arduino, but could not get any connection to it. Pressing the reset button does not do anything and nothing could be uploaded any more. Is my arduino dead or is there anything I can do to get it back to life?
