I have a Z817 tuner, I bought it 2nd hand, it came with the control cable but I do not believe it is the original cable. My FT-818 will not work with the tuner, it does not change mode and power and so the tune cycle fails.? The Baud rate is set correctly. The tuner works fine without the cable I.e. manually sending a carrier to tune. I do not know what is at fault, the cable, the ATU or the FT-818 ? Is there anything special with the original LDG cable? ? Any thoughts? ? Thanks ? Allan G4NNJ
