I hate to say it because it has very poor performance but a Super-Regenerative FM receiver (one transistor plus an audio amplifier) can pickup local AM or FM signals.
It slope-detects the FM (with lotsa distortion).

Its bandwidth is too narrow (causing distortion) or too wide (causing crosstalk with a few stations). It is overloaded easily by strong local stations so it must have its feedback fiddled with. Because it detects AM and FM at the same time then it picks up static interference noise. It causes interference to other radios.
