I have some electronics theory questions and some electronics
simulator questions pertaining to an Armstrong oscillator. I have
done some reading and have tried to come up with a design on my own.
Most books just show a general diagram with no specific values. I am
trying to simulate my design in LTSpice:
https://ilocker.bsu.edu/users/jalbers/WORLD_SHARED/Armstrong1.asc
Plotting voltages at points A and B, the circuit will work for up to
13 seconds (.tran 13) but does something strange after 14 seconds? I
speculate that L2 is going to keep adding more and more energy to the
tank circuit until things get out of control. I dont think that this
has happened quite yet though?
What do I need to add to the circuit to build the voltage at point A
to a maximum altitude and keep it there?
Any help would be greatly appreciated. Thanks
