When approaching SGF and attempting to receive their ATIS on 135.125 it is conflicted with MLC ASOS on the same frequency. This does not allow the crew an opportunity to get the SGF ATIS early enough for their arrival planning. SGF ATIS and MLC ASOS are on same frequency and located too close to each other. Change either's frequency; have digital ATIS available at SGF.
Air carrier Captain enroute to SGF reported MLC ATIS interfered with SGF ATIS when approaching from the southwest. The two airports are 183 NM apart.
