Hi, I am trying to do this design, and i am quite a newbie. I have everything hooked except the variable capacitor, my variable capacitor has three legs and I don't know which ones to use, I tried a combination, but nothing worked. Also, does it matter if i used a coil from an old AM radio? As you see, I am just a newbie, please help me though. Schematic: http://www.uoguelph.ca/~antoon/circ/fmt1.htm Thanks in advance, Zaid T.
