good morning Mr. Franco, I did a calibration with a 97cm antenna and a 25cm connection cable, I now put c13(220pf) and c14(100pf) and c9(450pf) and the output voltage is 0 volts without crystal and the voltage with crystal is 5.04 volts. without crystal and with 20cm antenna closed the voltage is 1.50v, as soon as the antenna is open the voltage drops to 0v .what is the problem? is c9 critical in this problem?
