With other radios ( I presume the ubitx is no different ) it is VERY discouraged to directly connect audio ports do to the possibility of a ground loop issue. It is best to use isolating transformers for this. There is one kit I have purchased in the past that was inexpensive. (I cannot find the purchase right now) I would also go so far to say its recommended to have isolation in the usb connection as well.?
I'm not saying this method won't work, it is just risking causing issues with your computer or radio or both. I found a pack of 10 audio xfmrs for ~$11 on amazon so it wouldn't be difficult to create your own.?
