Now lets see if I have the text set like it should . I have a Yaesu YO-100 that I wanted to try receiver monitor on a FT-101E. I have made the RCA cable connection from the FT-101E IF Out to the YO-100 J3 IF but nothing happens. I also see a modification of a small cable run from the FT-101 IF PB-1183. Has any of you ever tried this and does it work ?
