Step 1: Building the circuit
A decoupling capacitor is needed for battery operation =]
Step 2: Tunning the Circuit
Step 3: Specs and Troubleshooting
Freq: 530 kHz - 640 kHz possibly higher
If your tuning it for the first time do not use a portible radio it dosn't work well wit them.
If you know its getting power and you can't tune in try stepping away from it or touching parts of it to act like an antanna (I coulden't get wire to work)
Also it might not be enough amps i never mesured how many it took, but it likes computer power supplies and 9.6V packs.
If you want better audio put an inductor between the IC's output and audio in.
