So far, I have three cascaded amplifiers (see circuit on one of my previous posts in this thread) ganged together. I managed to pick up some AM stations (with distortion) without an antenna.

Here is what I am trying to do:
I want to make an FM radio that can pick up at least two stations in clearly. with the least about of radio interference.

I am not going to buy a radio kit because a) I can't afford it, b) It is usually more expensive than building your own receiver, c) The kit takes up more room space than if I built my own receiver. d) The only way to customize a number of features in the unit is to desolder components which wastes time. e) The kit may require a special adapter. I dont want to use any special adapters.

Once I get FM working, then I will turn my radio into packet radio and use it as a wireless modem.

I am tempted to use every single transistor I have (about 30) into the receiver alone.

 

Instead of conventional CAR Radio using a long dipole antenna.
This causes a lot of problems whenever when you drive u have to raise the antenna upwards to gain better reception. Else poor reception.

My idea of using a strip antenna can be mounted at the front windscreen making use of the car chasis as ground. How can we get a better reception here.

Please feedback any comments.

Bgrds,
Richard Lim
