Are the Relm/BK KNG-800 radios capable of using Motorola ADP encryption? We were told by a representative from a RF consulting firm (who will remain unnamed) that the radios do have that capability. I call BS as I was under the impression that only Motorola radios could do ADP (as it is proprietary to their equipment). On the Relm spec sheets, it states their radios are only capable of AES/DES/OFB.
