I think it is a minimum of 400KHz, since that is the alternate channel
spacing.  FM channels are 200KHz apart, each 200KHz channel is an adjacent
channel.

Typical selectivity for adjacent channels is only 6-12DB on normal tuners;
while alternate chanel selectivity ranges between 50-75DB.

What is the mimimum spacing required between fm broadcast stations located
in the same geographical area such as a city?

Thanks,

Don
