I am using Audiobox USB...I am consistently getting cellular interference when my cell phone is anywhere near the interface...if I put my phone in airplane mode it goes away...it doesn't matter if the phone is plugged in or not. I've thrown away so many good podcasts because of this problem. Turning the phone to airplane mode isn't an option as we need cellular signal for stats (sports podcast). I was thinking it was a chord but even when there's no chords in the inputs it still behaves that way. I've used it in many different locations so its not location...
So frustrated and becoming a occupational detriment. If I cant fix it I'm going to have to move on from this unit because its going to cost me sponsors soon.
