Narrative:

The white county airport (mcx) shares a CTAF/unicom frequency with the starke county airport (oxi). The two airports have identical runway configurations -- a single runway 18/36 -- and are located approximately 37 miles apart; well within radio range for pilots at both airports to hear one another.every time I visit this airport we run into one of three problems on the radio:(1) foreign student pilots who cannot adequately pronounce 'starke' or 'white' with enough clarity to avoid confusion.(2) pilots at either airport believing someone said 'starke' when they actually said 'white;' and beginning a conversation about who said what and where he/she is located.(3) pilots who use city names in their CTAF broadcasts -- monticello for white county; or knox for starke county -- which would be preferable if everyone on the radio were on the same page; which is not the case.the FAA should move either airport to a separate frequency so long as pilots will continue to make position announcements using 'white county' or 'starke county' as their respective airport name.

Title: A pilot reported that because MCX and OXI are in close proximity and share a common CTAF frequency; sometimes an aircraft's location is confused. Reporter stated some pilots do not clearly speak the respective airport names adding to the confusion.
