Crystals are not AM/FM sensitive, so this would work with either. If one assumes a first IF of 10.7 mHz, this crystal would receive 72.49, whatever channel that is; i.e., 61.790 + 10.7 = 72.49. That is making the assumption that the receiver you put it into is double conversion and uses a low side crystal rather than a high side crysta. Confuseing enough????
