Help, I am trying to simulate the circuit in LTspice, but I can't get it to work

 

Hi ren,
Welcome to AAC.
Please post your LTS asc file.

Here is my asc file, I dont know what I am doing wrong

 

you use ideal transistors
10uF takes time to charge up
10V modulation is perhaps too high and it's not decoupled
100nF might be insufficent for reliable coupling
10uH for HF decoupling may be too low
(also the oscillator part looks unknown/exotic to me)
