Building the SNAP circuit AM radio

The final circuit block for the project is SNAP circuit AM radio. As discussed in the UTC 7642 linear IC one-chip AM radio circuit of this chapter, the small 3-pin integrated circuit is the main component of the receiver device. In addition to having a one-radio chip solution, the SNAP circuits make the task of building the receiver easy and fun. The Parts list shown earlier in the chapter provided the name of the complete SNAP circuit kit, which includes the electronic modules to build the AM radio. By placing the electronic modules on a plastic board and snapping the components together, the AM radio can be built in several minutes. The complete electronic SNAP circuit AM radio is shown here:
