I'm trying to understand how am radios work. But i dont understand the most basic and fundamental parts required for reception of am radio. can some one help me out by telling me how to make the simplest AM receiver and please explain LC circuits.
So basically i need an antenna, a LC circuit that resonates at the required frequency, a diode (can i use any rectifier diode?), a opamp and earphones?
thank you again, i finally understand this. 1 more question please, now i know that LC circuits are used during reception of Am but are they also used to transmit RF? example: if i transmit a blank carrier wave and connect it to a LC circuit?
Crystal sets were old technology when I was a lad.
I used to sell crystal sets to people when I was at school. That is where I came up with the ferrite rod tuning method, it was a cost down on the variable capacitor. I made the boxes out of cardboard and used to sell then for three and six ( 3/6 ) and it cost me about two shillings to make. Not sure what that is in new money.
