Ken,
Are you getting a signal to the soundcard from both the I and Q
channels? What you are seeing is normal of only one channel is fed to
the soundcard.
In other words, check your cables. Plug in the left channel only into
the soundcard and see if you have a signal present, then do the same
with the right channel.
It may be a cabling problem, or your sound adapter may have only mono
input. Many external soundcards have mono input when the mic input is
selected, but may (or may not) when the Line In is selected - I/Q
decoding requires stereo soundcard input - if the input is mono, you
will see exactly the condition you report.

I am trying to get Rocky 3.7 to work with my KX3 similar to the display of the
P3 and my K3. I have Rocky 3.7 running on my laptop computer and Windows 8. Rx
I/Q is turned on in the menu of the KX3 and the cable supplied by Elecraft is
running to my Creative model SB1100 USB sound adapter. My sound adapter is
several years old so may not be the same as the new ones listed on the Internet.

I did not include the OUTPUT data as I am not using the transmit part
My problem is I get two spikes for every signal. One is the correct one but an
equal sized spike is shown on the opposite side of the screen. I do not think
this is normal as I don't think other hams would want a display with that
problem.
I have tried Rocky - View - Settings
Left/Right = I/Q
Left/Right = Q/I
Shift Right Channel Data by
-8,-7,-6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6,+7,+8
I don't know what else to try and I do wonder if the
USB sound card uses stereo for the microphone but I have not been able to find
that information on the Internet.
I would appreciate any help. I feel it is so close to working but not working
right.
