What MMTTY profile are you using when you run the comparison?

Got it figured out thanks to VE3KI.

Here's the trick (only works with N1MM)

Use two DI windows. Make the first one your regular MMTTY window and make 
the
second the 2Tone window. The second DI window is receive only, but that's 
ok.
You get the full benefit of a superior decoder and you can click on call 
signs
etc as always. I have been testing it our this morning and it works very 
well
(an understatement).  2Tone is clearly superior to MMTTY at digging weak 
signals
out of the noise. Try it, you'll like it.

The only drawback so far is the second DI window does not populate the GRAB 
box.
Not really a problem, you just click on the call instead of GRABing.

"OOK" means On Off Keying, i.e. like CW - the keying signal is either there 
or
it's not. Nothing in between.
