starting objective
I,ve been trying to build a decent radio for about 2 years. At first, I just read up on whatever I could about simple crystal radios and started building them, but I am not satisfied with that. I want to learn how to use transistors in my circuits to enhance the operation and power of my recievers. I have checked out almost every book from my local library on the subject,and I have learned alot. However, I am still unclear how the little 3-pronged devils work, how to bias them for the desired result, and all the little nuances of placing the different biasing types in a circuit. I have built about 30 different radios from other people's schematics,all crystal sets and AM band. Some worked,some didn't, and a couple worked great. But it's kinda' like copying a book someone else wrote- it looks good, but it don't make me a writer. I want to learn how to build radios for any frequency range I want to listen to, and that is why I asked the question-"how do you bias a transistor for a given frequency range?" I saw this site and thought I would ask the qustion, and after the responses I've recieved, I feel like an idiot for not coming here 2 years ago.
