Just a minor nit-pick: AM radio can be stereo. However its use is almost
nonexistent. See <http://users.hfx.eastlink.ca/~amstereo/amstereo.htm>

Telephone lines (POTS) have a frequency range of 300-3400Hz. That
means 7kHz mono should be enough, although 8kHz is generous towards
the transition bandwidth/roll-off.
