Hello this IK1TTD Gianpi and I have build a qcsx 40.... But at the power on I got a loud tone (much higher then 700 hertz described in the trouble shooting. It is impossible to wear the earphone as the tone is incredible loud, and can be heard also without earphone... I try to start the alignement, and the tone is always present, when I exit from the Align process, and I plug the antenna, I cannot listen anything except the continuous loud tone. Can you help me please ? Kind 73.-
