When FM radio first came out (just after the dark ages), many radios offered FM and a FMC setting, IIRC. It may have been FMA? Do any SDopers recall this? what was the purpose of this as both “bands” seemed equivalent. Some said the FMC setting got better reception, but I never noticed.
Bonus: Also, it seemed only portable (transisiter) radios had this setting…not car or stereo radios. Why?
I just want to confirm Jinx’s partial memory with my partial memory. I recall my first transistor had an AM, FM, and FM(something). The FM band was not split up and I never figured out what the FM(something) was for.
I think there was AM, FM, and AFC. AFC wasn’t a separate band, but rather a mode where FM stations “locked in,” instead of needing to be precisely tuned. You used regular FM for more distant stations, where the AFC locking would normally lock in a stronger local station in its place.
I remember that acronym and feature. (Not FMC or the other variants listed in prior posts). AFC was "Automatic Frequency Control’, I think, and our “stereo” (enormous wooden piece of furniture, with AM/FM tuner, amplifier, turntable, reel-to-reel tape, and a pair of speakers embedded in it) had AFC on the settings dial.
