BruceD,
Let me start a new thread specifically for ETF.
I don't know if my SBLive value card is full or half duplex. I've looked all over for any booklet that might have come with my computer, but can't find anything on it.

If your sound card is half-duplex, then you can burn the CD image for test signals that ETF also provides on their website and play it through your CD player, recording with the input from your RS SPL meter.
Is it a safe assumption that I could use any test CD if I choose the CD/half-duplex option regardless of the sound card involved? OTOH, no point in turning down free test tones since I've been unable to burn any from NCHtone generator without annoying pops.
I picked up a 50 ft. RCA to RCA speaker cable and a 1/8 to RCA adapter (part # 274-330b) at RS today. This will allow me to set the SPL meter on a tripod in my HT and run the cable back to my PC to record the data.
However, when I ran the setup test: file/new measurement/normal transfer function (with no connection to the sound card .. just the unconnected cable going to line in), I got info that said -1 dB in green... ??? I figured there should be nothing coming in. If I used the Low freq bandwidth test, I get Overload! +5 dB in red. ???
And that's about as far as I've gotten for now.
Do I need to get a 1/8 to stereo RCA so as to try both left and right channels? My 1/8 adapter says shielded audio adapter on the front and monaural on the back of the package.
BTW, I tried to use the ratshack calibration file I got from Terry's site (ratshackcorrection.mic) but it wouldn't load.. even after renaming to rs.cal).
Thanks for the help! Looks like I have lots of work ahead of me. (I still think the manual method will be faster.. just not as cool).
