Re: Dreaded dead transmit from SSB Calibration routine


 

Would it help to feed the QMX under update with a lower voltage, so as to reduce the strain on the BS170's during calibration?? For example, if I feed my 12V QMX with 9V, the power drops by about half.? I assume some of the issues during calibration are due to high transmit duty cycles that occur during the calibration process.??
?
I did successfully run calibration on my knock-around QMX.? Fed it to a 50 Ohm dummy load and didn't encounter any issues.? But when I update my daily-driver QMX, would reducing the supply voltage help to add margin during calibration???
