I got the Mark and Space out of sync with the Flex and WinWarbler

I can no longer work RTTY. I goofed something up and got them out of sync.
They don't seem to match. The mark and space lines will not line up in the center of WinWarbler.
And it seems that everything is outside the receive passband.

I can work PSK, (just made a few qsos), I can work JT65-9. All that works perfectly
It's winwarbler or mmtty that I goofed up something.
Anybody with ideas?
Glad to send you a screen shot if that will explain it better.

You may have accidentally set the transmitted Mark and Space tones to a different value than the Receive Mark and Space.  Check your setup/ Configuration files.I am not an expert in WinWarbler (I don't like the way the interface is laid out.)  Also, look for command buttons to center the display.  Is there a set up screen to set the "sweet spot" frequency?  THis is the center frequency of the signal, half way between the two tones, and is used in other software to help set the RX and TX signal to the center of a narrow filter's passband.  On the Flexes, in DIGIL, the "sweet spot" is 1500 Hz.

BTW.  I use FLDigi here, and have found it much easier to use.  But like many other things in the SDR world, that is all personal preference.

I am away from the rig right now.  But if you need more help later in the evening, I will hook my 6500 up to WinWarbler tonight and "mouse around" with it and see if I can figure something out.

Good Luck,

I hope this picture comes through.
I seem to have been able to get the mark and space lines close to correct.
I dragged the left side of the rtty passband to the left, and then dragged the right marker to the left
Until they were close to being about 220 cycle wide

As I was doing that, the rtty signal slowly moved to the center of the display.
as I was doing that, this little window in the slice kept changing it's numbers.
When I got to about here....

The above got me in the ballpark.
And appears to the eye as pretty close
now the question is...how do I tweak them so they are what they are supposed to be
as when I transmit, I can see that they are slightly off.

IN mmtty / winwarbler    i set  MARK  TO  1415 Hz   shift 170   and tap 512 
ham default  1415    and 170  
in 2T   PART OF WINWARBLER       mark 1415    spaced  1585  
seems   to work for me
