Wild Planet Radio DJ transmitter toy (FCC Part 15 AM)

A toy "DJ mixer" that plays cassettes and transmits on 1610 AM. The quality of the signal is actually very good, as it appears to be crystal-controlled. The range of the signal isn't very far, though. One of these would be useful for playing your favorite music on an antique AM radio. It works better than many AM transmitter kits I've seen, from companies like Ramsey. The only limitation is that you can't change the frequency, at least not without opening it up and modifying the circuit.
