AM means amplitude Modulation. there are different frequencies. Public utilities use AM mode in the Megacycle range- such as Departure Control- leave that Sominex alone. sorry. AM has its drawbacks, but covers a lot of ground in commercial and some Ham stations. FM has better sound quality and fidelity- often is broadcast in stereo- for music lovers- but has a limited range- max maybe about 55-l00 miles as the crow flies- better the higher the altitude of the receiving station. By the way Music is absolutely TABOO on all Ham and CB stations by FCC order. I do not know if this extends to what would pass as Ringtones, such as call signs in musical form- common with Cellphones but a very early radio beacon device thought up by Edouard Branly in France around l909. naturally he favored French patriotic themes- ringtones generating the opening bars of the Marseillaise- for example- (keyed) by a constant speed motor tripping pre-tuned tone generators-not too different from Orthographic signs such as the late, lamented H-E-R-M-A-N-S on 43nd st.
