Hello, I've decided to design myself a AM transmitter circuit. It's operating at around 600 kHz. The main problem is that I don't know how to properly make and connect this Colpitts oscillator to the AM modulator. I have set the Q point of the first transistor in the middle of the load line.. and oscillations are pretty good. But one thing I don't understand is to how properly pick the correct coupling capacitors. This is what I have designed:
Now, in general, what I need to know is this:
I'm aware of the fact that using such transmitters is illegal. I just wanna try it here in my room. I also know it's not recommended building it on the breadboard.
Would you help me, guys?
Thanks in advance!
Now, in general, what I need to know is this:
- How to properly pick C5 and C4
- How should the AM transmitter circuit look like connected to the Colpitts oscillator (ideally using transistors .. if you would be so kind you can also try to calculate it for me and then explain, I'd be much appriciated to you for this)
