I have a working crystal checker and have entered the circuit in to CM.
The DC analysis is working.
The AC analysis asks for a source.
I can't find a way to tell the program that the crystal is the source.
I just started with the program today.
I'm unhappy with some of the values of the components and also
want to add a buffer circuit at the emitter so as to have an AC out & DC out.
At 'DC Out' I have an LED with no series resistor. None seems to be required.
The switch is only for the simulation circuit.
