I was wondering about configuring the active audio filter kit that i demo'ed yesterday.. If I could configure it in such a way that it would amplify the input signal as well... after I did some research I found I was not alone.. This guy took the same Idea a few steps further and built a 40 M Receiver using the HY-Per-Mite Kit as two of the stages in the receiver!   

Check out the link ---really very cool minimalistic receiver design.. would it be cool to make a small transciver out of it!
