Unless things have changed over the past year or so, Backyard operates two facilities for their Muncie/Anderson stations.
The WLBC and WXFN studios as well as sales and traffic for all of the stations are housed in Muncie.
The other facility is located in Daleville (halfway between Muncie and Anderson) and houses WERK, WHBU, and the Max syncrocast. The market manager oversees both facilities.
In addition, I'm pretty sure they have an auxilary facility at the Mounds Mall in Anderson where the local morning show for WHBU is broadcasted from.
As far as the stations go, WLBC, WXFN, and WERK are licensed to Muncie, WHBU is licensed to Anderson, WMXQ to Hartford City, and WMQX to Alexandria. WLBC is Hot AC, WXFN is ESPN sports, WERK is classic hits, WHBU is talk, and WMXQ/WMQX are classic rock.
