Re: QMX+ no power output, low SMPS bias current


 

Richard, I'm glad you found the BS170 problem.? They probably sent you the wrong type of transistor, since all BS170s in those type of packages have the same pinout.?
?
I think the peak-to-peak voltage measurements that you made on the bands with high power (over 6W) probably have some measurement problem, since I don't think those voltages are possible with this design.? If they are real measurements, something is definitely very wrong.
?
Please post the power numbers reported on the Diagnostic screen, so we can compare them to the ones you are computing from the Vpp measurements.
