AM-receiver-using-ZN414

Notes.

• Assemble the circuit on a good quality PCB.
• The circuit can be powered from a 1.5V cell.
• Do not give more than 1.8V to the circuit as it will destroy the IC.
• For L1 make 80 turns of 0.3mm enameled copper wire on a 5cm long ferrite rod.
• K1 can be a high impedance crystal earpiece.
