I was just experimenting by replacing capacitors and inductors and the frequency continue being the same.

Well one of the reasons i asked was because if you change a 100uH inductor with another 100uH inductor you wont see any change.
Also, if you change them such that the capacitors and the inductor results in the same frequency, you also wont see a change.
That's why it is important to know what components you are changing, and from what values to what other values, and hopefully your measurements too.

 

How did you assemble this mechanically? It's possible you have an unintended feedback path that is bypassing the intended components.

I replaced different capacitors values.

What you mean mechanically ?. I just replace capacitors in the breadboard, I'm the LC tank.

Like one of these?


There is a lot of stray capacitance between columns, and they really become marginal for RF.

Try building it 'Dead Bug' style:

Ok but you still havent said exactly what you did. There is no way to understand what you are seeing without a full description of what you did.
