Interference on the AM band seems insignificant compared to this if it gets any worsre. This is an interesting article about scientists concern over artificial satellites radio emissions interfering with astronomy exploration.

There's a Giant Problem With SpaceX's Starlink Satellites
Scientists are worried.
..."If you look at the signal strength produced by these unintended emissions, it’s not unusual for them to be comparable to the brightest natural radio sources in the sky," Tingay told New Scientist. "It’s like taking the strongest sources in the sky and putting a bunch more artificial ones in the sky and making them move around a lot — that has a lot of impact, especially on experiments that seek to be ultra-sensitive."
Interestingly, SpaceX is emitting signals at ranges that are protected by the International Telecommunication Union, explicitly for the purpose of radio astronomy. However, whether Musk's space firm is acting illegally remains unclear as the transmissions are likely unintentional.
"No one’s breaking any rules from SpaceX or Starlink — these types of emissions are not regulated," Tingay told New Scientist. "But it is starting to become a discussion in the ITU as to how regulations over this type of emission could be introduced."...
