Am new to LT Spice and circuit design, however I have a solid grasp of the basics (I think), I've been trying to use ai chatbots to help with debugging but they just confuse me more! What is wrong here? I am trying to create an AM receiver for 900KHz, currently using both transient simulations and AC sweeps to view results and the above circuit design doesn't do anywhere near as intended. I know there's likely alot wrong so where do I start?

Polarity of V2 seems reversed.

 

Indeed, V2 is reversed for a PNP. Make it a NPN.
Additionally: No base bias on either transistor.

 

Before you start building real circuits, you need to compile and understand the inner workings of the building blocks required to meet your objectives.

1. Tuned RF circuit
2. RF amplifier
3. AF amplifier
4. Demodulator

As pointed out, you need to learn how a BJT amplifier works and how to bias the transistor properly.
