Frequency modulator won't oscillate
First of all thanks to @BrianDrummond, @Andyak and @Leoman12 !!

This is my circuit now :



This is my transient :



As you can see it now oscillates. Theres is a DC component on the Vout but it goes away with time. Its hard to simulate because it would take a while with Orcad (my software) and a high resolution (low max step size).

So the key points were to :


Change the DC source to Step
Add RB3
