Nothing on this site carries KO4LOJ yet (no repeater, APRS station, feeder, weather station or receiving station).

Only the licensee's name, class, status, dates and city and state are shown, never a street address. License data: FCC public records through Callook.info. QRZ.com opens in a new tab (its own terms and any sign-in apply).
