VarAC Freq busy light never turns off
I am trying to setup up VarAC with a IC-7300, and the Freq busy light is on all the time, and if I try CQ or anything else, it says waiting for freq to clear. I would appreciate some help. Thanks in advance.

I had this same problem with a yaesu FTDX. I was able to solve the constant busy by varying the filter width. There is a sweet spot around 2000 to 2200. But adjust and watch and the busy light will go out and the program works.
