[Elecraft] MMTTY issue

[Bob McGraw K4TAX]

For the radio setting I use AFSK A at 45BPS setting for MMTTY. Only use 
the signle USB cable between the radio and computer.   No other hardware 
or interface.

I don't use N1MM.

On one K3, I have the MMTTY Mark setting for 2125 and in the Engine window I am receiving the signal just fine, but on the 2nd MMTTY, there is so signal on the Engine window when I set the Mark for 2125.  I have to go down to the Mark setting of 915 to receive the signal (as I go down from the Mark settings of 2125 to 915 the signal comes from the left side until centered).
