[Elecraft] Your suggestions: side-by-side reciever CW comparison

[Darwin, Keith]

Here's my technique:

1.  Connect both rigs to the same antenna, through some sort of
(jury-rigged) Y arrangement.
2.  Feed the speaker outputs from both rigs into separate inputs on my
Behringer or Mackie mixer.
3.  Set rig's AF gains to about 1/2 way point to improve AF S/N ratio.
4.  Trim the inputs on the mixing board to get both channels to the same
level.
5.  Set both channel EQ control to the same (flat).
5.  Plug headphones into the mixer.
6.  Tune both rigs to the same signal.

Now, to compare the rigs, you adjust the channel volume controls on the
mixer.  Listen to each channel by itself or put one rig in the L ear and
one in the R.

You will definitely hear differences that you wouldn't hear if you
listened to one rig for 30 minutes, then disconnected, hooked up the 2nd
rig and listened for 30 minutes.

Oh, wait, you wanted a suggestion that didn't involve any equipment.

I'm looking for suggestions.
I would like to do a side-by-side comparison of receiver performance
with my second cw rig vs. the k2 without any equipment other than my own
ear.

Got any suggestions for setup etc?

Thanks
