[Elecraft] KX3 and Rocky 3.7

[Mike WA8BXN]

Ken, 
 
Getting the double signals very often is caused by not getting both I and Q
through the sound card into the computer. 
 
Here is a handy sound card oscilloscope program that can be used to see if
you are getting stereo input to a sound card. Get a male to male 1/8 cable.
Plug one end into the sound card. Touch the ring and tip at the other end to
see if you get input on one channel or the other (but not both just touching
ring or tip).

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.

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.
