Re: QCX LPF adjustments

As I understand this, pull out the LCD and then power it up. So no menu, and it will operate in default mode/frequency? Sending and receiving? In the QCX units there is a straight key, so I guess that it is used to get power out, and measure the power through the dummy load power pins to do the adjustment? But in the QCX+ version there is no key and the LCD is part of a PCB. So set it up for a straight key, unplug the LCD module, power up and use a straight key to get power output? Maybe it is feasible to do this procedure with the QCX+ version? I will probably have to work around the power button.

Yes, you can remove the LCD and power-up, once you are confident everything is working fine. I do this all the time, for making adjustments to the LPF toroid spacing. QCX works fine without the LCD; it only talks at the LCD, it does not check for any answer back. So if the LCD is not present, the firmware doesn't notice or care.
