The FM bands are more commercially 'interesting', because they're wider. One traditional FM band can fit tens of digital radio stations in, via DAB or DRM or HD radio etc.
AM bands aren't very useful for modern tech because you need huge antennas, can't do MIMO or squeeze much data in, etc.
- SoftTalker 2y agoYes if you remember back to pre-digital era, there were maybe half a dozen FM stations in most areas. Even without "preset" buttons you could tune them almost by memory by how far you had to spin the dial. Now there are dozens of FM stations, often low power but it seems like almost every 0.2 frequency increment has something.
