I know Eldon Bogart..no it wasnt him..Eldon put the FM on the air..with the help of Dave Hebert Consulting Engineer..back about 1990 something..
The Prosser AM was orginally KACA..it was an old call..that AM eventually became KARY Prosser – Grandview , which it still his now..
They ( Eldon and Dave) resurrected the call sign in honor of the original owner/operator of the AM station back in the 50s I think…and it was his Ham Callsign..W7ACA..I cant remember the guys name now..
