A transmitter transmits an AM sinal with a carrier frequncy of 1530kHz. When an inexpensive radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530kHz, the signal is heard loud and clear. This same signal is also heard (not strongly) at another dial setting.State, with reasons, at which frequency you will hear this station. The IF frequency is 455kHz.
