radio shack special
Hello to all,
I need to design FM receiver that is able to tune to commercial FM radio broadcast channels spanning from 87.5 MHz to 108 MHz, and to produce audible demodulated output. Doing some research, I came across radio shack special. I've tried to enter the author's website but it is dead. So I need some guidance from all of you.
1. Instead of using audio jack & headphone, can I change it with speaker? If can, May I know which type of speaker can be used?
2. If I want to design the pcb board using ultiboard , may I know which component in the ultiboard's library should I use to represent the source and drain coil? Another thing, since I just learning ultiboard using e-book, what component should be used to represent antenna in the ultiboard. Sorry for this stupid question but I really need guidance from all of you.
3. For the Drain coil, may I know how to make it has 3 turn tap?
Anybody has the copy of instruction from Mr. Patrick website?
Thank you for all your helps.
