Hello,
I am trying to simulate a simple transformer in KiCad 8.0.0 release build. I attach the project files for reference. I am using the 'coupled inductor' model with a .SUBCKT but I do not see the expected results in simulation when driving one inductor with a sinusoid. Would greatly appreciate any advice or pointing out any errors in the way I've implemented this.
Thank you.

The problem is your transformer subckt:

.SUBCKT BasicTransformer 1 2 3 4
L1 1 2 10m
L2 2 3 100m ---------> should be L2 3 4 100m
K12 L1 L2 0.99
.ENDS BasicTransformer

The secondary was not connected.
