[Using a toroid in a xtal radio]

Hey all,

I am building a Crystal radio with an NPN RF preamp front end. I was wondering if using a toroid in the tuning circuit would work okay in place of the huge coil I need since it is being amplified.

Cool, thanks for responding. Electronics tutorials doesn't go into enough detail for me but I will have to buils an oscillator from the second one and see if my bad luck with building can get it to work. :)

Any good e-books or weblites for oscillator design. I am hoping to learn the theory

Hi all,

Been into electronics for a while and am hoping to soon get into homebrewing. I understand most all of the basic electronic theory mostly self-taught over the years (only in 11th grade this year) and was wondering if anyonw knew any good books of websites or anything on the detailed theory of operation of oscillators.

I kave the ARRL handbook (am also a HAM KD7WNJ) but it just goes on and on about phase noise. I have also tried sites like electronics tutorials but they don't give enough detail for me.

Thanks in advance
