I have an Atlas DD6 C Digital dial that may be used with the R4C receiver. I do not have instructions for hooking the Digital Dial up to the R4C. Can anyone tell me how to use the DD6 C with my R4C? I know they can be used together, I just don't know where to plug what. If you can assist me with information, it will be appreciated.Thanks and 73, John, K5PGW
