I was running the arc from 87w down to 65w and noticed my signal meter jump around halfway through. Maybe 75w? Only data TPs and the signals are strong on a few. Most are intermittent, which further brings me to them being data. Anyone else see these?? It may be 81w. I used to get a CruiseSat mux there but it doesn't work. I never stored 81 into the vbox.
