This is a\n\tfun and simple project for both beginners and expert builders alike. Everything\n\tneeded to build a fully functional radio is included in the kit. Easy to assemble with no\n\tsoldering required. AM Radio IC Kit 3 is a great project to build with your child or\n\tgrandchild, scout groups and schools.\n\u003c\/p\u003e\n\u003cp\u003e\n\tThe kit contains small parts that may be a choking hazard. Adult supervision is always\n\tadvised while building the radio kit.\n\u003c\/p\u003e\n\u003cp\u003e\n\tThe circuit board is approximately 4 5\/8\" by 5\".\n\u003c\/p\u003e\n\u003cp\u003e\n\tThe Radio IC Kit 3 is a TRF ( Tuned Radio Frequency, Tuned RF ) type receiver. This is the most basic type of radio receiver\n\twith no regeneration or re-genitive feedback. The variable capacitor and antenna coil form a “Tank” circuit that\n\ttunes the radio stations frequency then the TA7642 amplifies the radio stations radio frequency then “Rectifies”\n\t(Converts to Audio) it then amplifies the audio and powers the Earphone.\n\u003c\/p\u003e\n\u003cp\u003e\n\tAM Radio IC Kit 3 includes radio IC TA7642 but the same board and circuit will work with any of the ZN414\n\tfamily of radio IC's. \u003cbr\u003e\n\t\u003ca href=\"\/product-category\/components\/integrated-circuits\/radio\/\"\u003eClick here\u003c\/a\u003e to browse our selection of radio\n\tIC's.\n\u003c\/p\u003e\n\u003cp\u003e\n\tThe TA7642 radio integrated circuit is based off the ZN414 from the 1970s. There have\n\tbeen several manufactures of replacement integrated circuits for the ZN414. The default\n\tradio IC included with the kit is the TA7642. We currently supply several alternate radio\n\tintegrated circuits; CD7642, MK484, TA7642, UTC7642, and YS414. Any of these can be\n\tsubstituted in the circuit for the TA7642. From our testing and customer feedback, the\n\tKM484 (not MK484) has the highest overall gain. However, it tends to fall into oscillation\n\teasily. The CD7642, TA7642, UTC7642, and YS414 have a gain just below the MK484.\n\u003c\/p\u003e\n\u003cp\u003e\n\tThe audio output must be connected to a piezo high impedance earphone or headphone.\n\tThis kit is not designed for use with magnetic earphones or headphones.\n\u003c\/p\u003e\n\u003cp\u003e\n\tRadio IC Kit 3 includes a ceramic earphone with wire ends.
