The different AM signals, an 80kHz tone on a 1.3MHz frequency, a 70kHz tone on a 1.5MHz frequency,  and a 60kHz tone on a 1.7MHz frequency. These signals are transmitted onto one wire. The LC tank filters in only the desired frequency and feeds it into an envelope detector, filter, and amplifier. To select which tone is seen at the output, change the LC tank Capacitor to 87.7nF to see the 1.7MHz signal, 112nF to see the 1.5MHz signal, and 150nF to see the 1.3MHz signal. Give the simulation a couple of minutes after tuning to lock on to each signal!
