Enter the schematic in Capture using only components from the PSpice folder.
Create a new simulation profile, and simulate it.
Transmitter:
For the microphone use a Vsin source with f=1kHz, V=1mV. For C1 use a fixed capacitor value, like C1=250pF.
Choose a simulation time of at least 5ms and a timestep<100ns.
After the transmitter works OK in simulation, continue with receiver.
Receiver:
Use the same LC values like in TX and tune a bit the cap for resonance. Link the TX output to the RX input with a high value resistor. At Out, connect a 10k resistor to ground and put a voltage probe.
It wold be simpler to simulate separately the TX and RX, simulation time is shorter. TX simulation is like before, for RX you need to put at the input an AM source made with behavioural components - from ABM library.
