Hi I'm trying to find data on a Granger 6015-3A/24 NST 23cm rptr. It has a D.O.T (department of transport).. I presume is for OZ certificate on it, but not able to find anything yet.
The sticker on the duplexer body depicts: Granger Associates SANTA CLARA. CA., USA any help appreciated TIA John VK4JKL
