I just got all the parts to make a simple AM transmitter from Scitoys. I followed the instructions from different websites and they still don't work. I don't know why it's not working. On my breadboard, the power rail is working. I used a multimeter to test various parts of the circuit. The transformer seems to work. There is some resistance with ohms. I don't hear anything on my AM receiver. Where do I even begin?
I'm not sure how to give proper credit but I figured it out with your help. I'd like to thank all of you for helping me. It really means a lot even though it was a bit rough. Don't push away newcomers. But anyways you've all been a great help! Each one of you gets two brownies.
The issue was the oscillator. Either it was dead on arrival or scitoys misspoke on the proper voltage. The new one megahertz crystal full can oscillator I got off of Amazon requires 5 volts. I put three AA batteries together and my AM receiver went instantly quiet. I knew it was transmitting something and I was so excited. I hooked up my phone to play some music and I was blown away at the quality. It sounded way better than I expected. I'm actually kind of shocked at how good it is.
This is my first step in making a super awesome AM radio. The next steps for me are creating different modules to create the best signal possible for output. The modulator, amplifier, and antenna design.
