Can anyone tell why when selecting the DC source this schematic does not work? It works in LTSpice and I want to implement this in real world as well.

You have to stop simulator, then click on switch diverter, click on the selector to change position to the other contact. Now you can click on start simulation. Bye

In other word, you have to start simulation with diverter positioned to the other contact, where is wired potentiometer.

Not potentiometer, sorry, but voltage source

Well I can start it that way indeed. Maybe it does not work initially due to startup conditions? I have built the circuit now and works great. I use it for receiver demonstration for a thesis. Anyway thx for your input @giomix

Yes, I think it depends from initial conditions used in math model. Good project.
