A transmitter transmits an AM signal with a carrier frequency of 1305 kHz. When an inexpensive radio receiver (which has poor selectivity in the RF-stage bandpass filter) is tuned to 1305 kHz the signal is heard loud and clear. The same signal is also heard (not so loud) at another setting. At what frequencies except 1305 KHz you will hear this station. The IF frequency is 455 kHz.
