The General forum is where users can discuss any topic regarding Motorola communications equipment - hardware, software, etc. There are also several focused forums on this board, so please take the time to ensure that your questions doesn't fall into one of those categories before posting here!
The secure board is located under the top cover of the spectra radio (both hi and low power models). It is the shape of an "L". There is NO shield over it. On the bottom side of it (once removed) you will see two sockets for the hybrids to go in.
