/^([A-Z]{1,2}|[0-9][A-Z])([0-9])([A-Z]{1,3})$/
Using preg_match(), this will split a callsign like N8LAI into
array(
0 => 'N8LAI',
1 => 'N',
2 => '8',
3 => 'LAI'
)
and you can use the information however you like (i.e. this is a
standard technician/general class call sign, located in region 8
Michigan/Ohio/Kentucky, etc.)
