I understand sound cards. For digital modes, we need to know how to set up audio coming in to the soud card and out of the sound card. When there is more than one sound card in the PC, we need to know how to set up digital mode applications for the desired sound card. All relatively easy (except the odd nomenclature in Windows Sound Mixer). A couple of years ago , I was having coffee with a neighbour ham who had a new Flex 100 and he was explaining that digital mode with that radio was a challenge (back then) and that they had to use "Virtual Audio Cable". I remember reading something about it, briefly, and then forgetting about it. There is something about the term "virtual audio cab;le" that causes my mind to melt, I have a hard time grasping what it does. Probably the word "cable" that is throwing my brain off.
The other day, I downloaded Virtual Audio Cable. I took a quick look , got awfully confused, and closed the application. I figure that this weekend, I will open it again and finally try to figure it out. Would I be far off if I guess that VAC essentially creates an audio IN and OUT path similar to having a second sound card? I am not sure that I have any ham radio applications that require VAC, but i figure I better finally learn what it can do. Andy K3UK
