I have a dumb question that has probably been answered before, but here goes:
Why aren’t the major stations like 0.5Mhz or 0.6Mhz apart rather than 0.8Mhz (eg 101.9 Fox and next 102.7 3RRR) if they only need 0.4Mhz (I assume some buffer is necessary), given we keep running out of frequencies for AM conversions? Is it not a better of use of spectrum?
