MMTTY issue

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

Re: MMTTY issue

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.

Re: MMTTY issue

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.
