As prescribed by FCC rules, a 2-way radio system licensee must post the current authorization for his system at the site of the principal system control point. Not sure if this regulation is still required but tradition calls for this notice for all base station radio gear made before 1980 (especially tube gear). This was scanned at 150 dpi and size is 8" by 6".
