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.

When in the Data mode you are using, press the SPOT/Pitch button (lower-left of 
the keypad) and hold. It should show the Mark freq. adjust to suit.

I am running to 2 K3 radios  for SO2R and having an issue with MMTTY Mark 
settings (running the programs with 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).

My setup:

1. I am running 2 external soundcards (Xonar) and have changed them back and 
forth between the 2 radios and get the same problem no matter which soundcard I 
use.
2. Have same problem no matter which filter I use (2.7 – 2.1 – 400)
3. DSP off
4. Filter controls are set identical
5. Data mode on both K3 are set to 45 baud AFSK.
6. MMTTY settings are identical  in their configuration.
7. N1MM+ configured to AFSK when MMTTY are launched.

All works fine in receive and transmitting when making contacts, just have the 
issue with setting the Mark being different on the MMTTYs.

Just wondering if their might be a K3 Config difference between the 2 I might 
be missing.

Any comments as to why I might be having to set the Mark different on MMTTY 
(2125 versus 915) to receive the signal to decode for the 2 K3 radios.

Thanks – David - ND4Y
