Re: QCX LPF adjustments
When there is no LCD connected, the QCX/QCX+/QCX-mini doesn't care. It just operates as though the LCD is there. It powers up and provided it is not the first time (when you must choose the band of operation), it will operate at the default VFO frequency etc which you have set up. Then you can tweak LPFs etc.
But I do not understand why you would need to do this on the QCX+ where the LCD is on a separate, perpendicular board, and does not impede access to the LPF toroids?
