Re: Does QCX Mini have DIY emission indication function? #qcxmini


Interesting! Are you sure the diodes are 1N4148? I will experiment with this circuit to find out how the led current is generated. Whatever it is, it is most likely a non-linear circuit and induces harmonics, as every non-linear component does in RF. But not a problem if applied before the LPF. BTW, what band is this QCX Mini?
