Oh yes, I had this question before but I am not at home so I do not have the absolute answer: in Audacity on the left set Windows WASAPI and on the far right the audio path which I presume is Realtek High Definition Audio.
Then set in the second to left box Speakers Realtek High Definition Audio (loopback) and lastly the recording channel which for the life of me I cannot remember. I would try mono and if that fails then it has to stereo.
The key to this is having loopback. In other words it is recording itself. The above is correct I think but if not should get you started.
You can of course record from the VAC TX line instead of the monitor but I presume you believe, and you may be right as I cannot remember, that this path is before EQ.
Not a direct answer but I’ve found the best way for setting up audio is to use a 2nd receiver if you have that option.
I do it a few ways.
One way, take a coax switch, put a dummy load on the COM port, put the Sun on port 1, select port 1 and put your 2nd receiver on port 2. You’ll get a nice solid signal on port 2 to monitor and record with.
I ditched switches for a patch bay so now I transmit to a dummy load that has an RF sampler on the line and I feed the output of that into my 2nd receiver...just be careful with your output power from an RF coupler/sampler. With mine it only takes 20W for an S9+50 signal into the 2nd receiver.
i use an SDR Play RSPdx as my second receiver with SDRConsole for doing the recording and it is the best way I’ve ever set up to do this. Just remember to use a wide enough bandwidth RX and to disable any RX EQ when recording.
