Current drain of only 10mA makes operation from 6-V battery feasible. National LM1820N IC serves for oscillator/mixer, two IF stages, and AGC, and LM386N AF chip provides power output of 0.25 W into 8-ohm loudspeaker. D1 is diode detector.-E. S. Papanicolaou and H. H. Mortensen, Low Cost AM Radio Uses Only Two IC's, EDN Magazine, Jan. 20, 1976, p 82 and 84.
