        It is possible to receive FM with an AM receiver. It is called
        "slope detection". When receiving FM signal turn the VFO slowly
        to the left or right of the signal and the audio will be intelligible.
        The audio quality will not be the best but quite enough considering
        the rare FM signals on HF. FM signals can be heard on 10 meters especially in the repeater section.
