I'm trying to perfect a 3volt transmitter. I was getting SOO sick of competing with other radio stations, so i tried to modify my receiver to receive below 88-108 MHZ. I did this by connecting a capacitor in parallel with the tuning capacitor. The trouble is, i cannot hear my transmitter below 88 MHZ, in fact, i can't hear anything. I did this same thing with another radio and was able to hear tv stations and other noises, but with this radio, all that i hear is that FM hiss.
My question is this: The receiver consists of three chips and a bunch of components. Is it normal for radio chips to limit how low i can go?
