I am working with MFJ Amateur radion products. I have the MFJ-564B IambicMFJ-564B iambic paddle that iwhich I need to wire to the MFJ-552MFJ-552 CW interface. theThe paddle is stereo (dits/dahs) and the interface is mono (when connected to paddle, only gives DITS). How can iI make a connector for it without rewiring my paddle? theThe paddle works perfectly with my other radios.
