Re: uBITX v6 Low Audio - Back at it again


 

Hi Topmaz,
?
Based on the lead voltages of Q30 and the fact that minimal current passes through R34, I suspect that Q30 is bad.? I would replace it and then recheck the voltage to see if Q31 and Q32 are OK.
?
Q70 is working, so it is not the problem I first thought it would be.
?
Note: Shorting out a blocking capacitor with the power on is not a good idea (both C50 and C51 are DC-blocking capacitors).? I had stated that I would touch each side of the capacitor, not both simultaneously.
?
Once the receiver is working, you can then do the calibration.
