The TC-4000 Radio Training System is a comprehensive and self-contained system suitable for demonstrating AM and FM radio transmission.  The system contains 4 (four) separate modules - the AM/DSB Radio Transmitter and AM Radio  Receiver modules and the FM Radio Transmitter and FM Radio Receiver modules. External Universal Power Supply UPS-2001 are recommended for the power source and Digital Storage Oscilloscope are required for waveform capturing and recording.
