Greetings, I wonder if you might advise me with an FM transmitter that I'm learning how to design, I hope you can help me , so, I explain the following:
I found a website and magazine which contains description about how to design a power amplifier, so I began to calculate the formulas of the page and the magazine, and I got different values so I decided to build both, but in neither case did well, only get a lot of noise and very little of audio input.
The first tests were done with a piece of wire approximately # 22 to make the antena, then use a coaxial cable 50 ohms, and for forming the dipole use the same cable # 22.
I hope you can help me, I attach my calculations to get an idea of what I'm doing and find my error.
For all thank you very much
